The whole place just oozes cuteness. The entire place is pink, even the chairs, with Hello Kitty images everywhere! The salon mainly caters to little girls with a full selection of cuts and perms, though it can get pretty expensive with "the works" costing over $200!
And no, I've never been to Japan but now I have another reason to want to go
