Immigration authorities on Sept. 7 banned a Japanese language school in Fukuoka from accepting new foreign enrollees after a Vietnamese student who wanted to quit was locked in room and monitored to prevent his escape. The Immigration Services Agency of Japan said the 630 or so current students at the Nishinihon International Education Institute in Fukuoka will be encouraged to transfer to other Japanese language schools. According to the agency, the trouble started after a Vietnamese student in his 20s expressed his desire to quit the school in October 2021. On Oct. 25 that year, staff members asked the student about his wishes in a faculty room. But when the student tried to leave, staff members detained the student for few hours in the room by using a metal chain and a padlock. Other school workers were in the room, but nobody tried to free the student. After the student returned to a dormitory room in the evening, staff monitored him from outside the room to ensure he would not run away, according to the agency.
