Why Japan
The Japanese people are the second-largest unreached people group in the world. Yet while being highly unreached, it is also largely accessible, leading to great opportunity for gospel proclamation and response.
- <1%of Japan is Christian
- 85%don’t know a Christian
- 95%have never heard the gospel
- 16,700people per church
- 37Mpeople in Greater Tokyo
A network of church-planting churches in Japan
Mustard Seed Network exists to glorify God by making disciples through planting gospel-centered churches in Japan.
Through planting churches across Japan, we seek to create hubs for future church planting, create resources for equipping believers in and outside of our churches, and pursue the lost through proclaiming the gospel to the 99% of Japan that doesn’t follow Jesus.

Romans 10:14–15 (ESV)How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!”
Join our support team
We can’t do this without the global church. God calls some of his people to go cross-culturally and others to send them by praying, giving, and equipping.
Would you prayerfully consider partnering with us through prayer and regular giving, to see gospel-centered churches planted in Japan and disciples who love Jesus and his word?
