Items made by inmates at the nation's prisons and correctional facilities went on sale Friday at Tokyo's Science and Technology Museum to promote understanding of such institutions.
At the two-day event, sponsored by the Justice Ministry and other groups, about 89,800 products presented by the Correctional Association Prison Industry Cooperation are on sale.
The products range from cupboards, chests, sofas and dining sets to shoes, accessories, soy sauce, noodles and memo pads.
About 43,000 inmates at 74 prisons and correctional facilities across the country are involved in making such products, according to the ministry.
This type of labor is a condition of all prison sentences. It serves as a rehabilitation measure so that inmates may brush up on or learn new skills in preparation for returning to society, the ministry said.
