In 2024, at a vocational high school run by Musashino Higashi Gakuen in Musashino City, a male board chairman was sent for indictment on suspicion of coercion for forcing a female student, then in her third year, to write an apology letter. On the 2nd, the Tachikawa branch of the Tokyo District Public Prosecutors Office announced that he would not be prosecuted. The decision is effective as of March 31, and no reasons have been disclosed.
