Missional Church in Japan (English)

Missional church is an ecclesiological concept which is grounded in the doctrine of the Trinity and finds its identity in the missio Dei—God’s mission. The church will re-discover its missional identity in God himself. The Missional church concept is derived from the biblical account and theological tradition of the church, and will provide a model that the church can use to be deep and total.[1] Particularly, for evangelical churches that are struggling in the post-modern situation, this model will be core in the re-evangelization of the West. If the missional church concept is grounded in the Bible, in theological tradition, and the doctrine of the Trinity, the concept could apply not only to Western churches, but also to churches across different cultural backgrounds globally. My fundamental question of this paper is, “How can the missional church concept be applied to Japanese churches for the evangelization of Japan?” I will argue that evangelical churches in Japan can rediscover their missional identity through retrieving and living into inter-relational participation in the Triune God. In this paper, I will present an overview of the situation and challenges of evangelical churches in Japan. This will be followed by some implications and applications of the missional church within the Japanese context.
             
The challenges of the Protestant church in Japan
Japan is known as the least Christian country in East Asia. Compared to Korea’s high Christian population ratio through the revival movement or to the massive growth of house churches in China, Japan seems to be unsuccessful in evangelization despite Protestant missionaries’ efforts for one hundred fifty years. In 2013, the number of Japanese Christians (comprised of Protestants, Roman Catholic, and Greek Orthodox) were reported to be approximately one million—just less than one percent of the total population. Statistics suggest that Christian populations of both Catholic and Protestants are decreasing. The Church Information Service reported that the membership of the Protestant Japanese Church started to decline from 2008.[2] Evidence of the downsizing of the Protestant church can be seen most clearly in the largest Protestant group in Japan, the United Church of Christ, whose members have gone from 201,468 in 1990 to 178,676 in 2013.[3] But the notable situation is that evangelical churches also seem to be stagnant or starting to decrease in membership. Table 1 suggests that six out of ten main denominations in Japan decreased in membership.

There may be some reasons for this downward trend. The most remarkable reason would be the decrease of the number of baptisms. After it had reached its peak (10,507) in 2002, the number of baptisms have been reducing year by year.[5] In 2012, the number of baptisms was 7,257; it declined about thirty percentage as of 2002.[6] Although the dwindling of birth rates may contribute to the decline of baptisms of Christian children within the last two decades, the rate of decreasing baptisms seem faster than the decrease in the overall Japanese population. Japanese Christianity needs a certain number of baptisms to grow just as the growth of population needs a certain birth rate. The downward trend of baptisms in the past decade suggests a difficult situation of Japanese churches. Despite evangelization efforts by the local churches and missionaries, Japanese churches are dwindling. Why is Japan such a tough place in the world to evangelize? What stand as obstructions to Christianity in Japan? We will find some reasons within the socio-cultural dynamics of Japanese society and people.
Most missionaries may consider why Japanese people find it difficult to accept the gospel and believe in Jesus. There are three main features that are serious obstacles to evangelizing in Japan: Japanese religious philosophy, the dominance of major religions that bind people by the family system, and the influence of modernity and post-modernity.
First, Japanese religious philosophy stands in stark contrast from the Judeo-Christian tradition. For example, Japanese people think humanity is not created by deities, but is descended from them.[7] The descendent of god is directly connected to the Japanese emperor’s family line, and this thought became a foundation of Shintoism. God cannot be separated from natural phenomena and human communities because of cosmological monism, and there is a lack of ethical concern for well-being by salvation.[8] For Japanese people, a basic teaching of Christianity such as “sin” is also difficult to understand.[9] Therefore, for Japanese people, a monotheistic God, the Fall, and salvation from sin seem hard to accept from the background of their religious philosophy.
Second, dominant religious systems which bind people in their family system keep people from Christianity. A Japanese indigenous religion, Shintoism embraced Buddhism and these religions became syncretic and co-existed in history. Under the advocacy of politics, especially the Edo period (1603-1868), Buddhism flourished and bound the Japanese family by its customs such as ancestor worship. In that period, all families were required to be a parishioner of a certain Buddhist temple. After World War II, the trends in nuclear families defused in part those religious relationships and customs, but the family system remained Japanese, particularly in rural regions. Dagfinn Solheim explains the pressure from the “family-system” on a Japanese who wants to be a Christian,
The main locus for the ancestor cult is the household, particularly the extended household. Usually, it is a family affair with no continuous link to the temple or shrine. The father has the main responsibility for the duties in regard to the ancestor altar, still found in most Japanese homes. The eldest son will eventually take over these duties or, lacking a son, the eldest daughter. When this son or daughter becomes a Christian, their relationship to the family will usually cause special difficulties as they are expected to be responsible to maintaining the ancestor veneration.[10]
For Japanese people, becoming Christian implies not only individual conversion but also the cutting off of all religious customs strongly connected to family and relatives. In recent years, Japanese people seem to be more released from the pressures of the family system. Nevertheless, “the family-system” is still strong at work within the Japanese mindset at the moment of one’s decision to become Christian.[11]
Third, the influence of modernity and post-modernity discourage many from becoming Christians. Japanese society is highly westernized, and the people have embraced modernity in their hearts. A rational mindset and reliance on science make it difficult to believe the existence of an invisible God and the miracles in the biblical narratives. In addition to modern ways of thinking, the deconstructing skepticism of post-modernity has penetrated people’s hearts and minds. Thomas Smail says, “The beginning of the twenty-first century does not have much faith or hope left in human goodness, political utopianism, or psychiatric salvation and indeed, in its more sophisticated post-modern expressions, has little faith that there is any possibility of knowing any universally binding truth about objective reality.”[12] Living in a fragmented post-modern society, people tend to keep a balanced plurality of faith rather than committing to one particular religion.
In addition to this situation, the massive economic development after World War II strengthened materialism and consumerism into the Japanese mindset. Japanese people tend to be absorbed in activities directly benefitting themselves such as working or leisure. Even though most Japanese people go to pray in temples or shrines, the purpose of religious activities tend to focus on happiness—material blessings—and their good health. This religious posture seems different from evangelical Christian beliefs, personal salvation from the Fall and service to one God who created heaven and earth. For Japanese people, becoming Christian and committing to the attendance of weekly Sunday services looks unprofitable for their lives.[13] In such a context, Japanese polytheistic culture—embracing any religions generously—keeps many in favor of a pluralistic religious attitude; New Year worship in Shintoism, funeral ceremony in Buddhism, and marriage ceremony in Christianity represents Japanese religious behavior.
In sum, these three socio-cultural aspects serve as barriers for Japanese people to receive the gospel and become Christians who commit to the church community. The Post-modern situation, in particular, makes evangelism difficult. The question may come up in our mind, “What effort did the Japanese church make in these tough socio-cultural situations?” Before I start the discussion of the missional identity for Japanese Christians, I will review the historical aspect of evangelism in Japan.
              Historically, Japan experienced three major evangelistic movements: 1) Catholic missionaries in the sixteenth century, 2) Protestant missionaries in the nineteenth century, and 3) evangelical missionaries post World War II.[14] The last movements were supported by the International Committee for the Christian Work in Japan, established by the North American Protestant denominations, which sent many missionaries into Japan and engaged with evangelism.[15] The growth of Protestants in Japan from 1948 to 1958 was notable—approximately one hundred-fifty percent.[16] Many evangelical churches in Japan received support from this movement and took over the planted churches those missionaries had founded. The pastors who had converted through the missionaries inherited characteristics of the Western churches. For them, evangelism meant inviting people to listen to evangelical preaching which emerged from the tradition of The Great Awakening. The evangelical programs were centered on the churches’ ministry. For example, four evangelizing crusades by Billy Graham in 1956, 1967, 1980, and 1994 were successful evangelizing events for evangelical churches in Japan. However, this conversion-preaching style of evangelism did not seem to lead to sustained growth. In the last two decades, new church movements, such as the cell-church movement or the Purpose-Driven Church concept, were brought to Japan and many evangelical churches in Japan tried to apply this kind of evangelism. Of course, some churches achieved notable growth by these concepts. Mainly, though, the decreasing or stagnant situation of Protestant churches suggests a limited influence of these movements upon the evangelical churches in Japan.

Rediscovering the missional identity of the evangelical churches
Most evangelical Christians in Japan may equate ‘mission’ to ‘evangelism’. Evangelism means bringing people into the church through church programs designed for outreach. However, we need to rediscover that the word of “mission” was from God’s nature, that is, the concept of the “missio Dei.” David Bosch says:
Mission was understood as being derived from the very nature of God. It was thus put in the context of the doctrine of the Trinity, not of ecclesiology or soteriology. The classical doctrine on the missio Dei as God the Father sending the Son, and God the Father and the Son sending the Spirit was expanded to include yet another “movement”: Father, Son, and Holy Spirit sending the church into the world.[17]
In this context, the doctrine of the Trinity should be the foundation of Christian mission and therefore, ecclesiology. The proper understanding of God’s mission will lead us to a hopeful engagement in his mission through our union with the triune God in Christ by the Spirit.[18] Bosch also explains the need to distinguish between God’s mission (singular) and our missions (plural)—our missions are particular forms of participation in the missio Dei.[19] The subject of mission is God himself, and we Christians participate in his mission through our missions. Ross Hastings describes our participation in God’s mission as our identity rather than an imperative:
Because by participation our being and doing as sent people will be ensconced and directed and empowered in his being as the missionary God, in the sent Son by the sent and sending Spirit. Our being and our practice as the missional church gathered in union with him, and our being as the sent people of God engaged with him in his mission will enable us to be Christ to the world and to do and teach as he did (Acts 1:1).[20]
Thus, the missional church should be the church that is sent by the triune God and participates in God’s mission—being and doing as the triune God is and does. Within this framework, the missional church’s acts cannot be separated from its being—being and acting will be kept together.[21] Of course, evangelism is one of the essential dimensions of mission. Nevertheless, the missional church must prioritize seeking God’s mission into the world more than implementing evangelism programs of the church. Ross Hastings explains, “We offer the church hope for carrying out its mission in the twenty-first century by moving beyond technique and even ecclesiology into theology proper—the triune God.”[22] This concept should be a significant paradigm shift for evangelical churches in Japan because this missional church framework is about identity first, and the church life that may include programs that are true to this identity.[23]
The doctrine of the Trinity should be central in the church’s being and its missions including evangelization. There are three features of the missional church that are grounded in the Trinity: (1) the church is the inter-relational community of the triune missional God, (2) the church is the Christocentric community seeking the mission of the incarnation and resurrection of Christ, and (3) the church is the pneumatic community invoking the work of the Spirit.
(1) First, the church is the inter-relational community of the triune missional God. The Christian gospel is the story of the Trinity, which is open for human relations.[24] The relationship within the triune God (perichoresis) –the mutual love of divine persons—will become the identity of the missional church. Miroslav Volf says, “The relation between the many in the church must reflect the mutual love of the divine persons.”[25] Human love without the Spirit  cannot correspond to the mutual love of the divine persons. The Spirit indwells in our hearts and invites us into the inter-relational community within the triune God. Volf quotes Moltmann who is a German reformed theologian, saying, “The Spirit dwelling through faith in the hearts of human beings ‘himself issues from his fellowship with the Father and the Son, and the fellowship into which he enters with believers corresponds to his fellowship with the Father and the Son and is therefore a trinitarian fellowship’.”[26] The perichoretic love in the inter-relational community proceeds to the mutual giving and receiving—we gives ourselves to others and we take up others into ourselves in a unique way.[27] The mutual love is not limited in the relationship in a particular church community, but it will be directed from the church to the world. Darrell Johnson reflects, “We are co-lovers with God of God; we are co-lovers with God of one another; we are co-lovers with God of the world.[28] The sentness of Jesus by the Father and founded in love and the sentness of the church by the Spirit help comprise the indispensable identity of the church.[29] The missional church never remains in a self-contained community. Moreover, the missional church has the dynamism of bidirectional sending and gathering—for sending and gathering is both incarnational and pneumatic.[30] Pneumatic gathering means that the missional church draws people to the faith and into the life of the church through the work of the Spirit. Through understanding and experiencing the doctrine of the Trinity, the church can stand on its missional identity and become a community which represents the mission of the triune God.
(2) Second, the missional church is the Christocentric community seeking the mission of the incarnation and resurrection of Christ. ‘Christocentric’ does not mean solely emphasizing Christ within the Trinity, nor looking only at Jesus’ salvation on the cross. The doctrine of the Trinity lets us focus on the heart of the Christian gospel that stands on the sentness of the Son by the Father—Christ’s incarnation and resurrection. The triune God’s self-revelation in Christ and Christ’s redemptive work for new creation are the essential parts of God’s mission. Hastings says, “[T]his incarnation-resurrection dynamic shapes mission to be a participation in God’s work, which has as its goal the forming of human persons ‘fully alive’.”[31] The concept of “fully alive” includes the broad perspective of true humanity. Our relationality, identity, gender, and work are restored in relation with God through Christ.[32] Thus, the missional church is a community which seeks the life that will be reformed into the fullness of the image of God (imago Dei) in Christ.[33]
The Christocentric community also represents Christ’s crucified presence. Christ’s crucifixion and his wounds and scars were the revelation of the triune God.[34] The missional church seeks the worship and communion that reveal Christ’s crucified presence. Christ’s crucified presence also reflects the biblical koinonia—cruciform self-sacrificing is the evidence in the church community life.[35] Preaching within a missional church will lead to proclamation of the truly good news that the triune God is for humanity and his love to the world is revealed in reconciliation by Christ on the Cross.[36]
(3) Third, the missional church is the pneumatic community invoking the work of the Spirit. The church started at the event of Pentecost (Acts 2:1), and through the empowerment and guidance of the Spirit, this first century church spread across the world. A sole focus on the evangelization programs and the seeking of efficiency by management impede the empowerment of the Spirit to the church in mission. Lesslie Newbigin says:
Mission is not simply the self-propagation of the church by putting forth of the power that inheres in its life. To accept that picture would be to sanction an appalling distortion of mission. On the contrary, the active agent of mission is a power that rules, guides, and goes before the church: the free, sovereign, living power of the Spirit of God.[37]
To invoke the work of the Spirit, the church depends more upon listening to the voice of the Spirit. How can we think about the work of the Spirit in the context of the missional church? Ross Hastings suggests, “Most critical to the effectiveness of the church on mission by the Spirit is that it stays true to its nature as the community of the Spirit, with all of the charismata at work in every member ministry, in a community that is organism first and organization second.”[38]
The missional church also seeks to be a polycentric community in which all persons can express their priesthood, inside and outside of the church, through the charismata of the Spirit.[39]
Moreover, as the prescription toward the evangelical church which emphasizes the role of teaching and pastoring for church leaders, seeking the gift of apostle, prophet, and evangelist should be a space where the Spirit works.[40] As a practical way to listen for the Spirit, the missional church can allow the Holy Spirit to work though group processes such as in ecclesial decisions by open conversation in communal dialogue.[41] Seeking the guidance of the Spirit and invoking empowering are indispensable aspects for the living church. When we offer an authentic and powerful spirituality of the Spirit such as in the church in Acts, the proclamation of the gospel will become easy because of the erupting power of the Spirit.[42]

The key concepts of re-evangelizing the evangelical church in Japan
There are four key concepts of the missional church identity for evangelizing Japan: (1) rediscovering the doctrine of the Trinity, (2) becoming an inter-relational community of the Triune God that penetrates Japanese society, (3) penetrating Japanese religious sensibility by the gospel of the triune God, and (4) overcoming modern and post-modern worldviews through embodying the Christian story in better ways.
(1) First, the doctrine of the Trinity should be rediscovered in the Japanese Church. Historically, the doctrine of the Trinity has received little emphasis within Japanese Christianity. Because of its polytheistic religious philosophy, Japanese Christianity focused on Christology to distinguish it from other indigenous religions. Tomoaki Fukai says, “In Japan, at any rate, the Christian concept of God was not that of the triune God, and the experience of worship in Japan was not worship of the triune God. We can say that the theological efforts in this period of the young church in Japan were to develop Christology from early monotheism.”[43] The style of faith also reflects the non-Trinitarian thought of Japanese Christianity. “The Common Doxology” by Thomas Ken provides an example of the involuntary elimination of the Trinity in Japanese Christianity. In the Japanese translation of the last phrase of this doxology, the Trinitarian idea of Father, Son, and Spirit is expressed as only “the great God”[44] Fukai points out that Japanese Christians have deemphasized the Trinity and cites James Torrance’s three views of worship (the Unitarian model, the existential-experience model, and the Trinitarian-incarnational model) to say Japanese Christians have possibly only practiced the first two types of views.[45]
Most evangelical Christians in Japan would be categorized within the existential-experience model that is preoccupied with individual religious experience. James Torrance points out the tendency of this model: “It emphasizes our faith, our decision, our response in an event theology which short-circuits the vicarious humanity of Christ and belittles union with Christ.”[46] It is surprising that the individual-centered belief model was imported into Japanese society which is both relational and communal. To retrieving the doctrine of the Trinity, the Eastern way of thinking about the Trinity—the social or communion model of the Trinity—will provide a consonant image and relationship of the Trinity to Japanese Christians rather than the Augustinian oneness analogy of the Trinity.[47] Tomoaki Fukai suggests a keen insight, “And now a community produced from the Trinitarian God (not an exclusive and individualistic community) will (stand in contrast to and) confront a community based on the Japanese value system.”[48] Rediscovering the doctrine of Trinity to retrieve the triune God’s mission is required. However, the missional church community should be a community which penetrates or coexists with Japanese communities.
              (2) Second, to successfully penetrate Japanese society, the missional church as an inter-relational community must cultivate a community focused in faith and mutual love. The doctrine of the Trinity teaches us that Christians participate in the life of a relational God.[49] Ross Hastings explains the consequence of this participation, “When we learn to love God and be known deeply by God, we will begin to know and love ourselves properly. Furthermore, ironically, it is as we give ourselves away to our fellow humans that we will discover ourselves.”[50] Miroslav Volf also explains the persons in the community of the Spirit, “The Spirit present in all Christians ‘opens’ each of them to all others. It starts them on the way to creative mutual giving and receiving, in which each grows in his or her own unique way and all have joy in one another.”[51] Relationships within the Christian community that are living in mutual love—that mutually give, receive, and grow one other—should be unsurpassed in Japanese society. This creative mutual giving and receiving can take many shapes in Christians’ lives. For example, sharing meals and breaking bread together once a week will be a significant way to cultivate God’s community in the Spirit.[52] In particular, such a mutual community can redeem an isolated nuclear family or single people who seek genuine community to support their lives.
Second, this inter-relational community should seek to engage Japanese society and culture in a proactive way. As Fukai points out, it is possible that a Christian community which has strong mutual relationship will confront to existing Japanese communities. Lesslie Newbigin explains the failure and stopping of growth of a “mission station” strategy that separates converts from their own culture and thus leads to them no longer having any influence on their non-Christian relatives and neighbors.[53] Rather, the cultural mandate is the goal of the Christian mission.[54] The missional church community must seriously undertake contextualization by becoming a community which embraces Japanese culture in an in-culturational way. For example, developing contextualized styles in funeral or memorial of the deceased rituals will help Christian communities to form an acceptable explanation within the strong Buddhist background Japanese society is located in. For the missional church, contextualization will be a more effective tool than evangelism.[55] By reinforcing the good in Japanese culture and forming a new culture, the missional church can show a significant presence in Japanese society rather than being an isolated countercultural community.
Third, to penetrate Japanese society, the missional church community must take advantage of various opportunities to invite people into this triune God’s community. For instance, the missional church will be open to those who recognize the church as a second community to support or encourage their daily lives. The community needs to embrace those who cannot fully commit to participate in church community because of their family situation or work style. Having openness to these kinds of people will expand the mission of God and his kingdom. Since Japanese society is a stressful society, Japanese people seek a place where they can release their stress and feel relief. Many Japanese people are wanting to receive the message of Matthew 11:28 more so than John 3:16.[56] Thus, a community that affords rest is significant in a highly stressful society.
 (3) Third, the missional church can most successfully penetrate Japanese religious sensibilities by emphasizing the gospel of the triune God that is dependent on the Spirit. Christian teaching can often seem forceful, manipulative, and even oppressive to Japanese people. Foundational Christian terminologies of sinning against God and incurring penalties for crimes against God can feel especially forceful.[57] The doctrine of double predestination seems to no longer be good news for non-believers because the majority of Japanese are expected to go to heaven after death in Buddhist teachings. The gospel—proclaiming the fullness of the image of God through the Trinity—is much less oppressing. Karl Barth’s theology of election that is recast in a trinitarian way is understandable.[58] The awareness of imago Dei will avoid the coercion or manipulative techniques in evangelism, and the dialogue which is led by the Spirit should be important.[59] This Spirit-led dialogue waits for the Spirit to do his work in his own time, affording Christian conversions more time. The missional church will consider conversion not just a crisis of belief but a process of belonging.[60] Evangelism in Japan, based on such a Spirit-led timetable, adequately prepares the soil rather than attempting to cultivate hearts through a slash and burn technique.
In successfully penetrating traditional Japanese religious sensibilities, emphasis on the Trinity reminds Christians that just as each person of the Trinity is constantly submitting to one another in humility, Japanese Christians need to approach non-Christians from a similar position of humility. Christians need to respect Japan’s traditional high virtue culture that is founded by historical religions. This culture stresses humble and harmonious cooperation. As Christians dialogue with non-believers, the aspect of coming humbly from the bottom is important. Lesslie Newbigin says, “Christians also have to come down to the bottom of their stairway to meet the adherents of another faith. There has to be a kenosis, a ‘self-emptying’.”[61] Japanese theologian Kosuke Koyama’s “Neighbourology” will help Christians to think about how to see and treat non-believers. He says:
We must discipline ourselves to see our neighbor immediately and straightforwardly. If we have some artificial cushions — and one of them can be our own ‘neighbourology’ –– between us and our neighbor, we fall into a dangerous pit of legalism. We must know the difference between the legalistic I and the missionary I. The former is the I who does not want to accept the real claim which his neighbor makes on him. The latter is the I who is sent to live in the midst of the reality of his neighbor, and his Christian existence hangs on the claim his neighbor makes on him.[62]
Most Japanese non-believers are from a Buddhist background. From his missionary experience in Thailand, Koyama’s neighbourology teaches us how we might become a neighbor for those who believe in Buddhism or other religions. In the dialogue with people who believe in Buddhism or Shintoism, becoming a neighbor, rather than presenting manipulative technics of evangelism, is crucial. For example, we build a relationship to neighbors first, and start to talk the story of gospel where the neighbors are interested or feel empathy on.
(4) Fourth, the missional church overcomes modern and post-modern worldviews by better representing the Christian story, maintaining our openness. We can offer humble and honest “faith-seeking-understanding” apologetics to non-Christians.[63] In such apologetics, God’s revelation in the Trinity is the matter of testimony and a personal reality.[64] Moreover, it is important to represent Christianity as a non-oppressive metanarrative.[65] The preaching of the missional church should be the gospel which seeks the end—our being “humans fully alive” rather than merely pursuing conversions for eternal life. We need to present the Christian story in embodied practice as a better story in the modern and post-modern world.[66]

A model of the missional church in Japan
The missional church concept can penetrate Japanese society and culture, and it has the potential for re-evangelizing Protestant churches in Japan. This missional church concept will encourage the church to become wide and deep. I will now present a model of the missional church in Japan as the implications of this research. The missional church in Japan will be marked by three key features. First, the missional church need rediscover its identity in the doctrine of the Trinity, and it will become deep and wide through its inter-relational community.[67] The community will stand on the love of the triune God and penetrate Japanese society through embracing people. Second, the missional church in Japan will seek to be both Christocentric and pneumatic. Both incarnational and pneumatic dynamics will direct the church as both sent and gathering, which are the bidirectional features of the missional church.[68] Third, the missional church will present the gospel through its being: the recovery of the person in the fullness of their personhood.[69] Following these features of the missional church, the evangelical churches in Japan can successfully disseminate the missional identity into its practices—worship, preaching, fellowship, and church structure.
The worship of the missional church will focus on the presence of the triune God. We need to remember that Jesus Christ is our great high priest and the church’s primary worship leader.[70] James Torrance explains that true worship reposes on and participates in the self-offering of Jesus Christ who alone can lead us into the “the Holy of Holies”. False worship, on the other hand, follows our own devices and traditions, falling back on “our religion.”[71] In this context, Sunday services are no longer mere preaching sessions, but opportunities to sense the presence of God through considered worship (such as prolonged sessions of musical worship which blend contemporary style music with hymns)—which enables the whole of the congregation to participate as priests.[72] In this Trinitarian form of worship, we participate through the Spirit in the Son’s communion with the Father.[73] The Lord’s Supper has also a significant role in worship. Communion will be held by the missional context that invites people to receive forgiveness.
The preaching within a missional church will understand the cross as a critical piece of the kerygma. Christ’s suffering on the cross presents the hope for a justified humanity and a reconciled universe.[74] The manner of preaching should consider Japanese culture and values. Paul’s inculturated and contextualized preaching in Acts 17 will be appropriated as a style of preaching.[75] The contents of preaching will truly be good news that justifies all humanity in Christ. Ross Hastings says, “The truly good news, the evangelion, that God has justified all in Christ, is liberating to preach in that it moves away from the selection model of election and enables the proclaimer to proclaim the good news to every human being that God is for them and that he loves them.”[76]
The fellowship of the missional church consists of diverse communities which invite people to the church community (“koinonia”) and cultivate God’s community through mutual giving and receiving. Sharing meals, doing hobbies together, and exercising for health by sports are a part of God’s mission to be “fully alive” as humans. Japanese evangelical churches tend to separate “biblical” things and “unbiblical” things, focusing solely on spiritual activities such as group bible studies or prayer meetings. However, the missional church cares for all aspects of our lives, and it retrieves everything through the inter-relational community within the triune God. This fellowship never forces members to be involved in activities. Rather, the church can unite the gospel and Christian interpretations of daily activities—relating food, health, arts, and work—to seek the model of inculturation within Japanese society. The missional church is a community that retrieves Christians’ vocations in the New Testament: all are called for the totality of everyday life.[77] Since Japanese society places a high emphasis on work, engaging with vocations and work is important for the church community. The trinitarian perspective of work shapes distinctiveness to each person—workers are not interchangeable cogs in human corporations.[78] This is the gospel for Japanese workers oppressed by high pressure and stress from overtime working.
The structure of the missional church should be considered within the Japanese context. Typically, Japanese churches have a membership system which separates Christians and non-Christians, for members of evangelical churches are highly committed congregants. This is evidenced by attendance every Sunday, tithe offerings and volunteer participation for church activities. However, to embrace less committed people and non-Christians, the missional church community needs to consider having a two-track structure. The missional church model may incorporate both the covenant community as bounded set and the congregation as centered set.[79] Through this structure, the missional church makes many different types of approaches toward the congregation and toward the covenant community.
Finally, The missional church needs to be aware of the needs of its margins, neighborhood, marketplace, and world.[80] Seriously undertaking a missional identity means that the church should care for difficulties and injustices in society with great compassion. In this context, the missional church has a mission for humanity to be “fully alive” not only for its own congregation but also for the margins and neighborhood, through caring for the poor and seeking justice for oppressed people. When the missional church can live in the mission of the triune God, and reinforce the good in the neighborhood through its community, the church will surely develop its width in Japanese society.
In conclusion, through rediscovering their missional identity and retrieving inter-relational participation in the Triune God, evangelical churches in Japan can penetrate Japanese culture and society and evangelize Japanese people successfully. The triune God’s missional community will be a hope for evangelizing in Japan, and it will disseminate a genuine Gospel in which Japanese people can experience being “fully alive” in Christ.

[2] This estimation is from All Japan Statistics by Year by the Church Information Service. The Church Information Service was founded in 1980 by an evangelical Christians in Japan. It provides many researches for the purpose to support evangelism in Japan. I used the data sheet which I received from Rev. Fukusaku (Vancouver Japanese Gospel Church) on January 25, 2014. The Church Information Service sent a short summary of the number of Protestant Christian to many Japanese churches each year.

[11] This finding is from the conversation with Rev. Tetsuya Fukusaku (Senior Pastor of Vancouver Japanese Gospel Church) on December 27, 2013. He said that many young Japanese people believed in Jesus during their long or short term stay in Vancouver, but some of them—especially young single ladies who lived with their parents—could not decide to be baptized because they were afraid of the negative reactions of their family members.

[13] Commitment of attending every Sunday service is not compulsion in Christian doctrine. However, before the baptizing, usually, an evangelical church in Japan let converts to make an oath to attend every Sunday service by very best they can.

[44] “The Common Doxology” by Thomas Ken mentions each persons of the Trinity in the last phrase. However, in the Japanese translation only translates the first two lines and refers to the great God “Ohmi-Kami.” This must be from the limitation of translating from Japanese to English. However, the fact that the phrase of the Trinity was eliminated in the process of the translation is significant.

[56] Japanese churches like to put Matthew 11:28 on their sign board. In my home church (Ibaraki Bible Church in Osaka), I heard a story of a single mother who saw the verse on the board of the entrance of the church in passing. The verse stuck in her heart and was the reason she decided to come to church.
[57] “Sin” is translated into a Japanese word “tsumi.” However, a primal meaning of “tsumi” is “crime.” Particularly, non-Christians who do not know the meaning of sin seem to be offended or confused by this terminology.
