2. Otaku shop Mandarake, Tokyo, Japan Want to fan your interest in Japanese manga and become an obsessive collector? Created by Masuzo Furakawa (also the CEO) who said, “Our mission is to take over the world using manga and otaku things”, Mandarake is Japan's No 1 chain of secondhand anime and manga superstores. Although it has several locations across the country, the 16 original stores—each specialising in a different otaku (a Japanese term describing for people with obsessive interests, commonly the anime and manga fandom)—are in the Nakano Broadway shopping mall, and are still the best. Over a million items line the shelves, and some 45,000 manga titles, anime DVDs and toys are bought and sold each week. Be sure to check out the surreal spectacle of the buy/sell counter, where people line-up to trade in treasures for cash, only to go right back into Mandarake's black-lined corridors to re-invest.
