John and Tomoko serve with the Japan Baptist Union (JBU) churches in the Kansai (western) area of Japan. They preach, teach, and lead Bible studies for congregations and groups across the area. Currently, youth, children and families are the focus of their work as they seek to promote children and youth ministries in individual churches and area wide. Youth provide the hope of the future of the church in Japan. However because Japan is a hi-tech modern nation, the children and youth are under tremendous pressure to succeed.  This pressure has led to depression, suicide and other domestic and societal problems.  

Tomoko has provided leadership for workshops, counseling and finding resources for parents, groups and churches looking for help to face the issues of modern society. Additionally, Tomoko has been active in the leadership of the Japan Baptist Women's ministries.

John regularly provides pulpit supply, especially for churches that are without a pastor. In addition he serves on the boards of various Baptist related bodies doing education and community service.

The Armagosts hope to see families strengthened, children and youth encouraged and lives changed as people discover the love of God shown through Jesus Christ.
