Bousingot is a used bookstore, cafe, and bar in Sendagi, Bunkyo City, Tokyo, where you can buy and read used books in Japanese and French. It serves coffee, tea, chocolate drinks, and cake, with quiet music playing. On weekdays it opens in the evening and you can stay reading until 9 p.m., when regulars who like books talk with each other. There are not many seats, so you have to pick a time when it is empty.
