An Indian man died Friday at a Japanese immigration detention center in an apparent suicide, the latest death in a system widely criticized over medical standards, monitoring of detainees and mental health care.

Immigration is a sensitive subject in Japan, where many pride themselves on cultural and ethnic homogeneity even amid a shrinking population and the worst labor shortages since the 1970s.

Guards at the facility found the man, who was in his 30s, in a shower room with a towel wrapped around his neck, the East Japan Immigration Center said in a statement.
