Michael and Chris Mason

Izumiotsu, Osaka, Japan

(1997 - present)

Michael and Chris Mason
The Mason's Ministry

Michael and Chris are career missionaries serving in the southern Osaka area.

The Masons arrived in Japan in 1997, and began serving at Sakai International Bible Church. In 2001, they were installed as the head pastors of SIBC and functioned in that role until 2012 when the church transitioned to a simple-style house church. At this point the church changed it's name to Oasis Church. Michael still provides leadership to the church, especially in the areas of teaching and leading worship. To learn more about Oasis Church, please check out the video below or visit the church homepage at

After serving 8 years at Kansai Christian School in Nara, Chris now feels lead to work in the area of member care. This will include providing support and encouragement to the many JEMS missionaries serving in Japan. Together with Michael, they will serve in this capacity while still ministering at Oasis Church.

Michael and Chris have one son, Luke, who graduated from Westmont College in Santa Barbara, CA in 2023.

Partnering with the Masons

While the Masons trust in the Lord to supply all of their ministry needs, they understand that the Lord uses the generosity of churches and individuals like you to enable them to serve in Japan. To this end, we ask that you might consider partnering with the Masons through the giving of your financial gift to the ministry of JEMS. Doing so will allow them to continue to share the Gospel of Jesus and build the Kingdom of God in the Kansai area.

You can also partner with the Masons through prayer. The forces against the Gospel in Japan are strong, but with your prayer support, the Lord can bring about much fruit. If you would like to pray for the Masons, their prayer letters can be found on their homepage at

Give online here or if you prefer to give by check, make the check out to “JEMS” and write our name on the memo line. Mail the check to P.O. Box 86047, Los Angeles, CA 90086-0047.

If you have any questions please call the JEMS office at 213-613-0022 or email Michael and Chris.

Thank you for your support.
