Church Plant Japan Mission

(Oikos Missional Community in Japan)

We are Jack and Megumi Adams along with our children Chloe and Ethan, called to reach the people of Japan through outreach, discipleship and launching missional communities where less than roughly .05% make up evangelical Christians making Japan the 2nd largest unreach people group globally.

Our mission is three-fold:

1. Make and multiply disciples.

Relationships built on trust and a safe place to openly share are foundational for discipleship to take root in Japan. A home as a place to gather to grow life-on-life relationships has proven effective as Japanese people as a whole will not show up to a church building even when invited.

Our vision is to multiply making disciples through using homes turning them into houses for God’s mission or Mission Houses much like the start of the early Church.

2. Encourage and support Japanese church workers.

Many Japanese church leaders we have built relationships with are over 65 years of age with no next in line leader. Many pastors are preaching at 2 or 3 churches due to pastors aging out or dying. This is leaving most with no capacity for reaching others to multiply the church body. We have much respect for Japanese pastors and their perseverance in leading church congregations for decades, most with less than 20 congregants.

We come alongside church leaders and participate in their local church services and invite them into outreach activities OR help them launch and sustain their own.

3. Fight for the broken and forgotten.

Japan is rooted in an honor-shame culture. Maintaining harmony in the group is crucial by fulfilling social expectations and obligations established in the culture or by society/family/group. The burden of avoiding embarrassment and concern for how others perceive an individual puts a lot of pressure on that individual starting at a young age. Those that can not live up to this standard often are looked down upon, talked about or being shunned by family/group OR one accpets their shame and decides to leave the group altogether resulting in loneliness, isolation and even suicide.

We launched an initiative - Not Alone. Our aim is to reverse the trend of isolation through public awareness and active engagement with those that are broken and forgotten with hopes of multiplying our efforts through other local churches.

Brief History to Present Day

In 2018, we started our mission at the southern tip of Japan, on the island of Kyushu in the city of Kagoshima. We have been connecting with locals, growing relationships at our weekly gatherings in our Kagoshima Mission House and building bridges with existing Japanese church leaders and fellow missionaries in Kyushu and throughout Japan. We have experienced God working through the ministries and outreach activities we have established. We have made Jesus known to many throughout our local community and have witnessed lives transformed by the love of Jesus as well as spiritual growth in the lives of those that God has given us to disciple.

In June 2026, we were approved as a registered non-profit organization by the Japanese Government as Oikos Missional Community giving us the ability to freely multiply our efforts in cities and regions where we are led to GO. July 2026, we secured our Tokyo Mission House where we will launch our 2nd missional community fall of 2026.

Our mission in reaching the Japanese is by the grace of God, fueled by prayer and sustained by the generosity of our financial partners.
