Komazawa University Tomakomai High School has announced that the 27-year-old teacher overseeing its national champion baseball team will be suspended for striking a player in June and August, dislocating the boy's jaw on one occasion.
Komadai Tomakomai officials made the announcement just two days after becoming the first school in 57 years and the sixth ever to win consecutive titles at the national high school baseball championship.
The school canceled celebrations that were to have been held Tuesday at the Hokkaido Prefectural Government in Sapporo and the Tomakomai municipal gymnasium.
At a news conference Monday evening, Principal Katsumasa Shinohara apologized for the violence and said the school will accept any disciplinary action, including losing the championship flag.
