This chain electronics store has about 40 shops in Japan, including its main shop in Ikebukuro, several locations in Shinjuku, Akihabara, and Shibuya. But this eight-floor store in Yurakucho is the largest, offering not only single-lens reflex, large and medium format, and digital cameras (plus all the accessories, including that all-important selfie extender), but also computers, cellphones, camcorders, watches, eyeglasses, luggage, toys, home appliances, sporting goods, and much more. Note, however, that it caters primarily to Japanese; English-speaking sales clerks are scarce, and export models are limited. Ask for the English-language brochure, and, if you’re buying sensitive equipment, make sure it will work outside Japan and comes with English-language instructions.
