Shokei Matsui (松井 章奎 Matsui Shokei [Akiyoshi], born January 15, 1963), also known by his Korean name of Moon Jang-gyu (Hangul: 문장규; Hanja: 文章圭), is a master of Kyokushin karate and current Kancho (Director) of the International Karate Organization Kyokushin-kaikan, one faction of the International Karate Organization (IKO) founded by Mas Oyama (1923–1994).
Matsui was born in 1963 and started training in Kyokushin karate at age 13. In 1976, he joined the Kita Nagare-Yama Dojo in Chiba Prefecture and attained the rank of 1st dan black belt in a little over one year.
Near the end of his life, some say that Oyama named Matsui (then ranked 5th dan, and clearly junior in rank to several senior instructors) to succeed him in leading the IKO. However this has been disputed with his family and Matsui. Reportedly, a letter by senior Kyokushin instructor Peter Chong noted that Matsui was surprised to hear that he had been appointed to succeed Oyama, but also that Oyama had earlier named Matsui before several other people as the leading candidate to succeed him. Matsui then became Kancho (Director). Following a dispute over the veracity of Oyama's will, Kyokushin karate as an organization divided into three main groups, led by Matsui, Kenji Midori, and Yoshikazu Matsushima.
Matsui is currently ranked 8th dan, and leads one of the IKO groups, supported by Yuzo Goda,Bijan Fard, Bobby Lowe, Peter Chong, and Seiji Isobe. Loek Hollander had previously supported Matsui, but withdrew his support in August 2010.
