The Japanese convenience store chain Poplar has announced its newest store opening in none other than Tachikawa Detention Center. As in the clink, the joint, the hoosegow: jail.

The store is not open to the general public, big surprise. The store carries personal care goods as well as snacks and refreshments for inmates, and aims to cater to staff by selling rice balls, box lunches, candy, and even some clothing items and toiletries.

Customers will be able to pay with PASMO cards (the re-chargeable train passes that you can use to pay at an increasing number of other stores set up with the card reader). Not that the inmates will have any use for the train fare. Or complain about any inconvenience for that matter…
