Onigiri, also known as musubi, has its origin back to the Yayoi Period from 300 BC to 400 AD, which was a time of Japan's warring states. Onigiri was an invaluable meal for soldiers and later became the iconic school lunch during the Meiji era. Today, onigiri is a common and popular staple in Japan, liked by the young and old, and are a convenient choice for work, picnics, school, sporting events, breakfast, lunch, dinner, and at gatherings. They are very affordable and can be bought at restaurants, supermarkets, convenience stores, and in food markets within department stores. Onigiri was introduced into Hawaii by Japanese immigrants in the late 19th century.
Why call it either onigiri or musubi? Both are the same thing, and it appears to be more of a regional term. Japan mostly uses the term "onigiri," with the exception of the older residents in Yamaguchi and Hiroshima prefectures, who call it "musubi." As most of Hawaii's immigrants came from these areas, the term "musubi" became the preferred name.
Located behind the Senso-ji Temple in one of the back streets of old Asakura in Japan, Yadoroku Restaurant is the oldest onigiri restaurant in Tokyo that is considered old-school and had started serving onigiri since 1954 when white rice was a luxury item. It is a family-owned restaurant and is operated by third generation Yosuke Miura during the lunch hours, and his mother operates it during the evenings; his grandmother initially started the business.
The onigiri is made into a triangular shape with selected seasonal white rice from across Japan, filled with carefully selected ingredients, and wrapped with crunchy Edomae seaweed, which is known for its rich flavor. Its fillings are carefully chosen from all over the country. Choice of fillings include: ume from Wakayama, kelp, salted fish, chili pepper leaves, red pickled ginger, salmon, ikura, salmon roe, shirasu (young sardines) from Hyogo, cod roe from Hokkaido, and kasuzuke. The owners are always on the lookout for ingredients that meet their standards. The amounts of rice and filling depend on the specific filling, and there is a balance between the amount of rice and the amount of filling. Only white rice is used, with the yellow parts removed. The rice is choice koshihikari, which is made in a cooking pot for rice called hagama. It is still warm, as each onigiri is made to order. Miso soup toppings include Nameko mushrooms, Shijimi clams, or wakame seaweed.
We were there during the lunch hours, which is 11:30a to 5:00p, Mon to Sat. For 690 yen, I got two different onigiri of my choice (wakame and pickled ginger), tofu miso soup, and takuan. The onigiri was partially wrapped with the nori to keep the nori crisp, and served on a bamboo basket server. The rice was "oishi" (delicious), as it was sweet and fluffy; the fillings were freshly made with the right seasoning and texture. The hot miso soup was savory and perfectly done; and the takuan had the right sweetness and crunchiness. Perfect in every way! And not your everyday onigiri, but a heavenly one that I could tell the difference. Wow!
Dinner hours are from 6:00p Mon., Thurs., Fri., and Sat. (closed Tues/Wed for dinner). Closing hours may vary, as they close sooner if they run out of rice. The serve alcohol during the evenings only, but you are limited to only one cup.
The small restaurant has eight ¸counter seats, and two tables with four seats each, for a total of 16 seats. It has a friendly, casual atmosphere, with the restaurant name meaning good-for-nothing husband. The owner is very attentive to your needs.
Get off at the Asakura Station. Restaurant is on Kotonoi St., between Senzoku St. and Kaminari 5656 Building. A cute onigiri shop - a hidden gem in the backstreets of Tokyo.
