Am in Japan on assignment for a couple of weeks and am looking for things to fill my weekend with. So far I have climbed Mt. Fuji and visited Kyoto and strolled through Edo Palace in Tokyo. Now I am looking other fun things to do and sights to see, but also I am looking for good places/stores/recommendations for: Buying authentic Japanese stuff, either cultural or unique to Japan. Good places for Anime/Manga stuff, beyond the touristy stuff. I am looking especially for places that sell cells and other collectibles. Other sights worthy of visiting on the weekend. Also I would like to experience Tokyo's nightlife, anybody can recommend a good club that will not turn a westerner away? I am into Techno, Trance and other electro type music. Thx for any tips.
