The Japanese version of Walmart with the exception of a floor selling luxury goods under lock and key...even then, I wouldn't purchase anything designer here because I have heard that they are sometimes fake. It is a loud place, very busy, and dirty. If you don't want to make the trek to Tokyu Hands, then you may chose to settle for D.Q.
A large store that has products ranging from sporting goods to bathroom toiletries. If you have looked everywhere for something in particular then this should be your final destination. It is always extremely crowded here so either be prepared to walk up and down the many sets of stairs or wait in line for the next available elevator. Also, don't forget to receive your customer point card on the main floor. Happy shopping!
