While popcorn may be one of the hottest snack trends in Japan right now, it's still unexpected that Cinnabon, of all places, started selling its own gourmet version this month. The popcorn comes packaged in small (¥380) and medium (¥750) sizes and can be found at the chain's Roppongi branch (Roppongi Center Bldg., 6-5-18 Roppongi, Minato-ku, Tokyo; 03-3470-4780; www.cinnabon-jp.com) and some others. The popcorn is coated with a generous amount of cinnamon and brown sugar and, strangely enough, tastes quite a bit like a bowl of Cinnamon Toast Crunch.
