Luke Kenichi Muto (Japanese: ルカ 武藤 謙一, Ruka Muto Kenichi) is a Japanese Anglican bishop. Since 2013, he has been bishop of Kyushu, and from 2020 to 2024, he was the 19th primate of the Nippon Sei Ko Kai, the province of the Anglican Communion in Japan.
Muto was elected as primate during an online synod due to COVID-19 restrictions in October 2020 and installed during a small service on November 5, 2020.[1]
During his tenure, in 2022, Muto consecrated Maria Grace Tazu Sasamori as bishop of Hokkaido. Sasamori was the first female Anglican bishop in east Asia.[2]
