If you're in town as a tourist, chances are you're not really looking to burden yourself with furniture (for great souvenir ideas, see the MUJI Xmas collection of suitcase-friendly items). But the thing with the best interior shops — especially in Tokyo — is that they pretty much double as sleek design museums, with all the latest and greatest in the world of Japanese (and international) interior design on display, and with free "admission" to boot. Do make a point of checking the sleek stylings of the Maruse store, located midway between the Shibuya and Daikanyama stations (2-12-205 Sarugaku-cho, 03-3461-7330). Designed by Makoto Koizumi, expect an interior that matches the items on sale. Keep in mind that interior also covers glasses and tableware, so you may in fact be able to find a souvenir that matches the size of your luggage after all.
