Whimsical onigiri dealers Risaku take their rice balls seriously: they have 30-odd filling options to choose from and bring in only the highest-quality ingredients from all over Japan. The shop uses Koshihikari rice from Gunma prefecture for its onigiri and miso from Kagoshima and Gunma for its soups. Other ingredients for fillings and sides are also carefully selected and brought in directly from trusted suppliers, including cod roe from Fukuoka and ume plums from Tanabe, Wakayama prefecture.
Popular flavours include salted pork with pickled radish, cream cheese with cod roe, conger eel, and grilled miso. Rice balls can be enjoyed in the store or ordered for takeaway, but we suggest securing a spot at the counter to have either a morning or lunch set. The former is the best deal here, coming with an onigiri or two, plus miso soup and/or side dishes – all for ¥600.
