As the 1990’s appeared. LT. Duplessis had now returned to Japan as a navy Commander and received instructions from the Lord to continue building the ministry once organized as a home fellowship. Commander Duplessis had clearly received divine orders from the Lord to transition the military fellowship to an off-base location, in order that more Japanese would be reached with the gospel and in 1991, established the first off-base Full Gospel church in Yokosuka City, under the name of Full Gospel Christian Church. A Board of Directors was established and full-scale Christian ministry service programs went forth. The new church began to draw both Japanese and non-military base worshippers, which included Japanese university students, foreign embassy workers and English teachers, throughout the Kanagawa and Tokyo areas.
Throughout the remaining decade, under the missionary leadership of Pastor and Missionary Duplessis the ICM would see tremendous change as many foreigners began to worship within its ministry doors. Now operating as an officially registered foreign missions organization, ICM was received into the Japan Evangelical Missionary Association (JEMA), where it holds a long-standing membership of many years. Outreach into the local Japanese and international community took place which included: feeding the homeless, visiting hospitals, prisons and shelters for battered women and holding dozens of Christian retreats and evangelism outreach activities. In 2005, upon receiving his ministry appointment as Bishop Duplessis, led the ICM to expand its missionary borders and church-planted into nations outside Japan in fulfillment of its vision requirements to send those forth with ministry callings - into the uttermost parts of the world. Thus, from 2006-2010, ICM mission branches were established in the countries of Cameroon, Ghana, Nigeria and Philippines and pastors were appointed over each branch. A ministry headquarters was officially set up in Japan at the ICM ministry location in Ebina City, Kanagawa. A ministry book store was established to supply the ICM branches and a ministry gospel choir program was established as a pre-evangelism outreach program to reach Japanese people.
In 2010, the ICM officially launched its vision-based missions bible school and partnered with Good Shepherd Ministries International, by facilitating programs through its International School of Ministry (ISOM) under license, to educate believers in basic foundations of the bible. The ISOM program, which now outreaches to local Christian communities throughout Japan, now functions as an independent learning institution, established and operated under the name of International – Schools and Learning Academics (ISLA). To date, the ISLA ISOM School has held seven academic/education recognition and graduate ceremonies and continues to graduate dozens of students. The number of student enrollment continues to increase as more nations flow into the ministry vision and work. In 2014, the ICM transitioned into a fully Japan registered independent Church ministry and Christian business organization as it prepared to integrate completely within the Japanese Christian and general civic societies within Japanese.
The ministry continued to strengthen its ties with local, governmental and civic groups. In October, 2016, ICM celebrated its 35th year of ministry work in Japan. Anniversary programs were held and were highlighted by the return of Reverend Paul Arrington, a founding ministry elder and keynote speaker for the 35th Anniversary Worship Service.
In 2018, ICM ministry leaders saw the need to emphasize hearing from the Lord on the next steps for His guidance concerning the direction of the ministry and its vision. Ministry prayer coordinator, Minister Mera Tilos, took charge and led a 9-member missions team to Seoul, Korea from Tokyo, Japan for a combined 4-day church growth conference and prayer summit. The results of the 4-day mission ignited spiritual transformation throughout the ministry and led to an all-ministry focus on living a more empowered life through the presence of the indwelling of the Holy Spirit and an uncompromising prayer life.
To highlight a few, in December, 2018 the ICM expanded its evangelism effort to include a deeper penetration into the harvest of souls, by expanding its global presence through the introduction of online line ministries in 2019. It was truly a God-directed move as both ICM and the world had no idea that the devastating presence of the global Coronavirus Pandemic would strike all nations and severely cripple the mission of the church to provide in house places of worship and Christian programs. ICM was ahead of the Christian communities as it already had ministry in place and smoothly continued its mission from the Lord.
As the year waned, there was concern by leadership for whether to remain in the current church worship facility, Apollo Building, Ebina City, Kanagawa Prefecture, due to continued long-term building lease requirements. Both ICM Overseer and Pastor Enomoto discussed this concern and sought what would be God’s next instruction for a physical place to worship. Pastor Enomoto emphasized the need for the ministry to acquire land in order to be more deeply rooted and organizationally registered in the nation of Japan. After fervently seeking the Lord and hearing from Him, Pastor Enomoto transitioned the ICM in Japan from a church-building based organization to that of a home church fellowship and online worship service ministry. This was done in order to begin preparing the church to purchase and own land and a building for the future. By doing so, the ministry would be meeting one of the major requirements to be legally registered in Japan as a religious organization. The full start of the "Nehemiah Building Plan", led by Pastor Enomoto began. This plan serves as the main ministry vehicle to provide future funds, through seed faith, to purchase and build ICM facilities in Japan.
In 2020, a new Pastor by the name of Reverend Kenneth Evaurherhe joined in pastoral ministries in the ICM, who received confirmation from the Lord to both enter into holy matrimony with ICM Pastor Enomoto and work alongside her in the ICM Vision. Reverend Evuarherhe was welcomely received in to ICM and consecrated into the ministry pastoral ship in May, 2021, where he received the laying on of hands, by a 12-clergy, multi-nation presbytery, during his installation service, led by Bishop Duplessis who appointed Reverend Evuarherhe to lead the team of ICM pastors and serve as the ministry spokesperson for the ministry founders and overseer. Through the direct combined efforts of Pastors Evuarherhe, outreach and ministry expansion continued and in mid-2021, the planting of a ministry branch was established in the Tokyo, Japan district of Shinjuku. ICM graciously enjoys the benefit of having all its currently serving pastors, being fully trained seminarians, who hold ministry degrees from Covenant Theological Seminary, USA.
