Calvary Chapel Iwakuni is a church plant out of Calvary Chapel Okinawa. It is located about 40 km southwest of Hiroshima, in Iwakuni city, just outside Marine Corps Air Station Iwakuni. Sensing God’s call to Iwakuni, Mike Silva, a former U.S. Marine Officer, and his family left military life and moved to Iwakuni in September 2005. They started a Bible study in the living room of their home on November 13, 2005. God, by His Grace, established a church out of that Bible study.  In September of 2013 Pastor Mike and his family were called to Orlando, Florida and Pastor Glenn Phipps and his family from Calvary Chapel Okinawa moved to Iwakuni to continue the work began through the Silvas.
The Phipps family moved to Okinawa Japan in 2003 to serve alongside Pastor Rick Barnett at Calvary Chapel Okinawa, sent out of Calvary Chapel Living Water in Corona, CA. In 2013, they moved from Okinawa to Iwakuni, Japan, to serve at Calvary Chapel Iwakuni. Calvary Chapel Iwakuni is an English speaking church ministering primarily to military and government employees at Marine Corps Air Station Iwakuni. Currently the church has two people on staff- Glenn and Keegan Davis, who recently came up from Calvary Chapel Okinawa with his wife to help the ministry in Iwakuni. Up until July, Roy and Nancy Toma, a missionary couple with the Japanese Evangelical Missionary Society, had been serving alongside the church as unpaid full-time staff.  They have since felt God calling them back to the states and have returned to California.  The rest of the leadership within the church is comprised of volunteers from within the body.  As it is a military base, families typically live there for three years before moving to their next assignment, so the turnover rate is very high, which provides a unique challenge to maintaining leadership within the ministries of the church. Adding to this challenge, many of the service members are gone for several months out of the year for military exercises and deployments, sometimes with little advance notice.
