In March 2014, Seita & Emma and their 4 kids moved to Tokyo, Japan to serve together with a team of missionaries in a church planting effort in Toyosu in the Tokyo Waterfront area. After serving on staff at Grace Harbor Church for three years, they started a new church, Toyosu Community Church, in 2017 in partnership with Grace Harbor Church.

About Japan

Of the 126 million people in Japan, with 35 million in the Tokyo metro area alone, only less than a half of one percent are evangelical Christians. Japan is one of the leading nations in the world in technology, finance, and many other ways. But underneath the façade of prosperity, Japan’s spiritual poverty runs deep. In a culture where reputation and success is idolized, many people constantly live under tremendous pressure, and many have struggled to find their identity and purpose in life. It is estimated that more than 700,000 young people have withdrawn from society altogether and live in voluntary confinement in their homes. For over a decade, more than 30,000 people each year have committed suicide in Japan. The Japanese people need the gospel of Jesus Christ, the only message that can set them free from their fear of failure and burden of shame.


Toyosu is an area on a man-made island, about half a square mile in size, located in the recently re-developed Tokyo Waterfront area. The population of Toyosu is more than 35,000 residents and counting. Toyosu and the surrounding area’s population is expected to rise above 200,000 by 2020, and there are many young married couples with young children moving into this area. Jesus said, “The harvest is plentiful,” and Toyosu is one of those ripe harvest fields, into which Jesus is sending laborers to start a church called Toyosu Community Church.
