At Tochigi Prison, Japan’s largest women’s correctional facility located north of Tokyo, a notable shift in the inmate population highlights broader demographic trends affecting the country’s penal system. The medium-security prison, which houses around 400 inmates ranging in age from 19 to 91, is witnessing an increasing number of elderly prisoners, many of whom have been repeatedly incarcerated.
Among those detained is Kyoko, a woman in her late seventies serving time for involvement in a cryptocurrency scam. She represents a segment of older inmates who sometimes return to prison multiple times, often due to non-violent offenses linked to social isolation and economic hardship. “When you have money, that sort of thing happens,” Kyoko said, acknowledging her role and expressing remorse.
Human Rights Watch highlighted in a 2023 report that Japan’s prison population is aging, with many older prisoners committing petty crimes such as shoplifting. According to Hirotsugu Hori, director of Tochigi Prison’s general affairs division, about one-third of the inmates are aged 60 or older, and some suffer from dementia or require assistance with daily tasks such as bathing. The prison adjusts to these needs by providing meals that are easy to eat and offering appropriate care.
The inmate demographic also reflects Japan’s growing international ties, with roughly one-third of prisoners being foreign nationals, primarily from Thailand, China, Mexico, and Vietnam. Despite a minority of inmates convicted for violent offenses including homicide and robbery, prison officials report that serious conflicts are rare, typically limited to verbal disputes.
The facility, surrounded by rose bushes and characterized by lavender dormitories, a library, and a cafeteria, employs inmates in compulsory labor, producing goods like flags, key chains, and origami ornaments. The prison pays them about 56 yen (26 pence) per hour for their work. Kyoko described the tasks as manageable and even enjoyable, attributing her positive attitude toward detailed work.
A typical day at Tochigi begins at 6:30 a.m. with roll call and breakfast in the cells, followed by two sessions of work lasting a total of nine hours, separated by a lunch break. The daily schedule also includes exercise, further roll calls, dinner, and four hours of free time before lights out at 9 p.m. Rehabilitation efforts include the use of “reflecting rooms,” where inmates meet with staff to discuss their progress, as well as access to vocational courses in fields such as hairdressing, beauty, nursing, and business.
Japan’s reliance on incarceration is notable given the relatively low daily cost to taxpayers—approximately 2,400 yen (£11.48) per prisoner—compared with other countries. Takayoshi Yamamoto from the Justice Ministry’s correction bureau pointed out this cost difference, citing the average daily expense in England and Wales at £147.
The growing elderly inmate population at Tochigi underscores challenges facing Japan’s prison and social care systems amid demographic changes, highlighting the need for policies addressing recidivism, aging prisoners, and rehabilitation.
