A great place to get your electronics and appliances. You get great discounts when you use your point card. However, don't expect anyone to be able to serve you in English (even if they claim to have English speaking staff, your novice Japanese will be much easier to understand). They have 5 or 6 floors. The top floor consists of restaurants and luxury items such as bags and pens. The Thai restaurant is actually quite good, suprisingly enough.
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.
