June 2025 Update
  • Pray that more non-Christian Japanese people would hear the gospel message and come to accept Jesus as their savior. Pray that Grace Harbor Church would have some more capacity to share the gospel more effectively.
  • Pray for the transition that Grace Harbor is going through from 3 staff to 0 staff. From staff-lead church to volunteer-led church. Praise the Lord that God uses this transition to make GHC to learn more about priesthood of all believers.
  • Pray Seima and Noako's parents to accept Christ even in their mental weakness and challenges.
  • Pray for Seima and Naoko as we go through Mentored-Sonship program. Pray that we become more humble and Christ-like in our walk with the Lord.
  • Praise God for the salvation of Mr. T using various christian contacts from his time in Australia, and his friendship with Christian friends in Japan, and the faithful work of JCFN's returnees ministry. God uses various contacts to bring salvation. Pray for his growth as Christian and his preparation to get baptism in a near future.
January 2025 Update
Seima and Naoka are involved in a church planting ministry in downtown Tokyo, Japan, that is affiliated with Mission to the World (MTW), Presbyterian Mission International (PMI). This is not just a single church plant—their desire is to see a city-center church-planting movement take root throughout Tokyo. Through this they hope to see Tokyo, the biggest city and the most lost city in the world with only 0.23% of the population professing Christ, transformed by the gospel. Grace Harbor Church in Toyosu (a city-center area of Tokyo with 200,000 people without any church) was planted in 2015. They intentionally target non-Christians, building relationships and sharing the gospel with people who have never heard the gospel before. They have about eighty adults and thirty children gathering each Sunday.
