SIM is a century old catalyst for global mission with more than 4,000 workers serving across six continents. Dedicated to prayer and care, we bring good news to hard places because there are people living and dying without the gospel.


A3 (formerly Asian Access) began in Japan by coming alongside visionary pastors and leaders to partner in new ways to grow the church. Now with a network across Japan and a strong history of partnership, together we work toward a movement of Christ-like leaders and disciple-making churches.


SIM and A3 have embarked on a new award-winning strategic partnership. Recognized for its innovation, this partnership is truly a new way of doing mission together, each bringing their own strengths and committing to a common kingdom vision. All A3.Missional Partners workers serving in Japan come through an SIM sending office and are members of both organizations.

Together, SIM and A3 send global workers to Japan to partner with local churches in holistic outreach to make disciples and develop leaders and churches, catalyzing innovation for reaching Japan for Christ. Each Missional Partner benefits from the strength of their SIM sending office and the strategic work of A3 in Japan.
