Bio: Jeffery & Akiko Sonnenberg

Background Info:

Jeffery & Akiko are a Canadian and Japanese missionary couple with tremendous missions experience. Jeffery went to Japan twice with Asian Access as a short-termer. Upon completion of his seminary studies, he returned to spend 3 years heading up the English Ministries of Soka Evangelical Free Church in Saitama.

During this time, he met Akiko, a fourth generation Japanese Christian (which is a rarity). Akiko was a university student actively involved in campus ministry as well as a member of the English Board at Soka Church. They worked together at the church in English and Japanese.

They were married in Canada in 1998. They spent a year doing post-graduate studies at Gordon-Conwell Theological Seminary in preparation for further mission work in Japan.
