<h2>Dorm Supervisor X Indicted for Assaulting Three Students</h2>
An assault incident occurred at Oki Gakuen High School, a prestigious sports school in Fukuoka Prefecture. Police have sent documents to prosecutors charging former dorm supervisor Mr. X, in his 30s, on suspicion of assaulting three students.
The dormitory, which serves as the students’ living base, should be like another family. Yet within that inescapable world, violent assaults took place.

Students A and B, both members of the baseball team, were grabbed by the head by Mr. X and forced to slam their heads together, then beaten and kicked all over their bodies. Another student, C, a member of the golf team, was struck near his right eye by a tumbler thrown at close range. Blood poured out, and it was said that if it had been just a few millimeters off, he might have lost his sight.
There were also other dorm students who suffered verbal and physical abuse. Mr. X, who ruled the dormitory through fear, had another side — that of a professional dancer.
An entertainment industry insider familiar with Hakata’s music scene said:
“The band Mr. X performs with is active mainly around Hakata, but this year they’ve toured 12 locations across Kyushu, the Chugoku region, and even abroad. They’re quite popular among reggae and funk fans. Many admired Mr. X’s aggressive performances, so it’s actually more surprising that he was a dorm supervisor at Oki Gakuen.”
Indeed, the band’s official website shows Mr. X delivering sharp, high-energy dance performances.
At Oki Gakuen, he also taught dance to the school’s dance club, and some students were aware that he was a dancer. Records indicate that Mr. X was involved in the choreography of the dance performed by the dance club at a dance festival held in Fukuoka Prefecture in August of last year.

<h2>Why Okinawa Gakuen Hired Mr. X</h2>
Mr. X, who had earned a reputation in Fukuoka’s local music scene as a respected reggae dancer, was reportedly seen hosting drinking parties inside the school dormitory.
“I think it was around last fall,” said the parent of student A. “Dorm supervisor X held a party inside the dorm. People with tattoos and flashy hairstyles came — they looked intimidating. When my son peeked in and made eye contact with Mr. X, he glared at him with a look that said, ‘You know what’ll happen if you talk.’ It was terrifying.”
But why would the school hire someone like him as a dorm supervisor in the first place?
In response to this site’s inquiry, Okinawa Gakuen said it was unaware that Mr. X was active in a reggae band and explained the hiring process as follows:
“Around July 2023, the coach of the dance club resigned to work at another school. Mr. X, the husband of that coach’s senior, was introduced to us because he could provide dance instruction. Beginning August 2023, he was contracted to teach two to three times a week for two to three hours each session. During his instruction, he never raised his voice.”
According to the school, in April 2024, Mr. X’s wife — who holds a teaching license — was hired as a temporary staff member in the admissions department. When the previous dorm supervisor, a man in his 70s, retired, the couple volunteered to take over the dormitory, officially becoming live-in dorm supervisors on July 1 of that year.
Regarding reports that Mr. X hosted drinking parties inside the dorm, the school stated:
“The school prohibited Mr. X from drinking alcohol in student areas of the dorm, but did not ban him from drinking privately in his own quarters after dinner service. Until the victim’s parent reported it, we had never received any complaints or confirmed that he was holding parties in the dining area. Such gatherings in shared student spaces are inappropriate and not permitted.”
As for Mr. X being sent to prosecutors, the school added:
“Although Mr. X has been referred to prosecutors, our school believes he must face the appropriate criminal consequences for his actions. We intend to continue cooperating fully with the investigation.”
However, Mr. X has yet to apologize to the victims or their parents. One parent expressed anger and fear at his lack of remorse:
“X has many intimidating friends, and since he hasn’t been arrested, he’s still free. We’re genuinely afraid he or his associates might retaliate against us. But I think my son is even more terrified than we are.”
The violent incident left not only physical injuries but also deep emotional scars. The question remains — does Mr. X truly grasp the gravity of what he has done?
