Visitors are encouraged to pet, play with and feed the dozen or so rabbits "on staff" at this small backstreet cafe. Several different breeds are represented, and most of them seem to be quite lively (especially compared to typical residents of a cat cafe).
The cafe's interior space is relatively small - just three tiny tables, with floor seating for visitors. The rabbits take turns scampering about and spending time in their cages, with only a few running loose at any given time, although you can play with the ones in their cages too.
A dish of greens and shredded carrots for feeding the rabbits is Y150, and coffee and soft drinks are included in the cover charge, which is Y700 for the first thirty minutes or Y1100 for the first hour, plus Y550 for each additional thirty minutes.
There is a wide variety of breeds at this venue including Holland Lop, French Lop, Netherland Dwarf, American Fuzzy Lop, Jersey Wooly, and Lionhead and Angora mixes. If you're in the mood for a rabbit cafe tour of Tokyo, Ra.a.g.f also has a somewhat larger branch in Jiyugaoka, with around two dozen rabbits. The shop's initials stand for "rabbit and grow fat," in case you were wondering.
