Chapin, Craig & Yumiko

At age 14, Craig was convicted of the Lord’s call to mission. He kept that call before him through his teens and 20s, as the magnitude of the gospel grew in his understanding. At age 26, the Lord led Craig to Japan, and he has served Christ there for the better part of the past 35 years.

Raised in a Buddhist family, Yumiko fell in love with classical music at an early age and studied at Kunitachi College of Music. In her mid-20s she met Christ through a church-run English school. Eight years later, she and Craig had their first date and married in 1999.

The Chapins work with the Christ Bible Institute team in Nagoya, Japan—the third-largest city in the world’s second-largest unreached people group. Craig teaches New Testament at Christ Bible Seminary, serves as the seminary’s academic dean, and manages the seminary library. CBI’s vision is to see the gospel of the glory of Christ cherished and proclaimed throughout Japan. To this end, the seminary equips Christians in Japan for the work of gospel ministry.

Yumiko is involved in Bible studies and employs her musical skills for the seminary and in church ministry, playing piano for worship services, for seminary ceremonies, and for choir rehearsals and concerts. In addition, she helps Craig to express biblical truths with sensitivity to the language and culture of Japan.
