Shibuya 109 mall is the flagship of Tokyo kawaii – nine floors of the cutest of the cute – bunnies, kittens, layers of ruffles, tons of pink. It is the quintessence of Tokyo teen style. Target audience of most stores is school girls and students, so prices are not that high. The stores are densely packed in a narrow building, so it will take you about three hours to see them all. By the way, they sell girls stuff only. 109 men is located closer to Shibuya Station.
