Onigiri Asakusa Yadoroku

This family has been serving onigiri in Asakusa for three generations. Ingredients are arrayed inside a glass case, as at a sushi shop, to be formed into onigiri on the spot. Offerings range from salmon and dried plum to rarer items such as herring roe pickled in sake lees and opossum shrimp preserved and simmered in sweetened soy sauce. Offering a wide range of ingredients allows customers to choose based on their physical condition; the area was once home to numerous bars and pubs, so customers would drop in for morsels to soothe constitutions punished by a night on the town.
