A 42-year-old inmate at Nagano Prison has asked the Nagano District Court for a provisional injunction ordering authorities to provide the nutrition he needs, saying a severe eating disorder has left his life at risk, Kyodo News reported.
The prison is in Suzaka, Nagano Prefecture. The man argues that withholding adequate substitute nutrition violates Article 25 of the Constitution, which guarantees the right to life, and the Act on Penal Detention Facilities and the Treatment of Inmates.
According to the petition, the man developed an eating disorder with a psychological cause while in custody around summer 2025. He weighed 60 kilograms when he entered the facility and fell to 49 kilograms.
He was then prescribed six nutritional supplement drinks a day, each containing 375 kilocalories. The petition was filed on Tuesday.
