Jay & Caitlin Greer

Tokyo, Japan

The Greers work with Mustard Seed Network to plant churches in unreached areas. In 2011, they planted their first church in Osaka, Japan, and in 2020, they planted a church in Tokyo, the core of the world’s largest urban area by both population (37 million people) and economy ($2 trillion). This church continues to grow and is part of a larger church-planting movement to reach Japan with the hope of Christ.
