Originally from Takamatsu, Kagawa, Kumi encountered God and was baptized while studying English in the UK. After returning to Japan, she joined a church planting team in her hometown, mainly serving as a worship leader and a children’s English teacher. From 2018, she served as a worship leader at The Bridge Fellowship in Tokyo for nearly six years. She married in May 2021. Starting in April 2021, she studied and completed a two-year internship with Samurai Projects. While continually being renewed and growing through the gospel herself, she hopes to see the gospel reach people in Japan through worship, the Word, and the many ways God works.
