Cat Café

You'll be able to find cat cafes in a lot of areas of Tokyo especially near large stations. For example, Shibuya, Shinjuku, Asakusa, Ikebukuro, Akihabara, etc. The price depends on the store and how long you spend there, but usually you're expected to order some kind of beverage and if you stay for 1 - 2 hours, it'll be about 1,500 - 2,500 yen.
