Omusubi Kororin, a shop devoted to omusubi (rice balls), opened on Friday, November 13, 2026, along Shiomi Nawate — the street that runs beside the moat of Matsue Castle — about ten minutes on foot from the castle, a National Treasure. The shop is takeout only.
The rice is 100 percent Nita rice, a brand rice grown in Okuizumo. It is cooked in a gas-fired pot, polished only just before use, and every drop of water that touches the rice is purified, the shop says. The opening fell right in the new-rice season, so the natural sweetness of the rice itself should be at its best.
Among the rice balls on offer are a grilled rice ball flavored with shijimi clam soy sauce from Igeta Shoyu, and a dashi-chazuke rice ball — a rice ball served in dashi broth — made with Uffurui nori, a rare seaweed harvested locally in Lake Shinji, available in limited quantities. The shijimi soy sauce is also sold in the shop.
Hours are 10:00 a.m. to 4:00 p.m., or until the rice balls sell out. The shop closes on Wednesdays, and because it is run by a small team, there may be occasional extra closures. Free parking is available behind the shop. For the latest hours, check the official Instagram (@omusubi._cororin). Shiomi Nawate, with the moat alongside, is a castle-town stroll in itself — now with a freshly made rice ball in hand.
