Happy Science Ginza Book & Cafe is a two-floor book cafe in Ginza, Tokyo, where you can read and buy Japanese-language books. It sells yakusen curry, pasta, sandwiches, matcha, and iced lattes, and you order and pay on the first floor before going up. There are five seats on the first floor and additional seating on the second floor, with Wi-Fi and power outlets at some seats. The seats are close together, which is uncomfortable when the cafe is crowded.
