Japan, home to the world’s oldest population, has been dealing with a challenge it didn’t foresee: senior crime. Complaints and arrests involving seniors, and women, in particular, are taking place at rates above those of any other demographic group. Almost one in five women in Japanese prisons is a senior. Most are in jail for shoplifting; some because they had no other option for survival, and some took the opportunity to go to prison—for a room, warm meals, and company. Loneliness drives many of these women to find stability and a community, which prison can provide them.
