Nekobukuro

Nekobukuro, Cat City... The name really speaks for itself, I think. It's located on the 8th floor of a department store in Ikebukuro called Tokyu Hands. The store has some crafty things, and a whole floor dedicated to stationary and another to bags and travel supplies, but noting too interesting to report short of the pet shop on the top.

Sorry about the lack of photos of the actual building, but my camera was not cooperating with me and did not want to focus on anything out of arms reach. 

Basically the whole place is two rooms that have ramps, stairs, and walkways all over the walls and ceilings for the 15 or so cats that live there. You pay 600 yen and go in for an unlimited amount of time. I got there just at the end of nap time, I think because the cats all started to wake up a few minutes after we got there.

Keep in mind this is a busy shopping district in Tokyo, so if you want to come visit the cats, try to go during school hours. That seriously decreases the chance that the place will be filled with 5-10 year olds chasing the cats with strings tied to sticks; or all the benches being full of high schoolers trying to keep the hair off their uniforms. All in all it was a fun place to go, and the cats were great, though they do make me lonely for my cat back home.
