I stopped by the new Muji flagship store on a mini Japanese retail pilgramage to Times Square. The New York branch of Kinokuniya moved to 40th & 6th from Rockafeller Center a few months ago, and I also visited their new store.
Both stores were great, but the Muji store, despight the great light, open plan, and glass shelving, still seemed too small for the range of their products. The flagship Muji store in Tokyo is enormous, and even includes a grocery section. If they opened a store like that in Brooklyn I might never shop anywhere else.
