Everwhere in Fukagawa area
Fukagawadon is a bowl of rice topped with a miso-based stew of asari clams and green onions. During the Edo-era, asari (clam) gathering was very active in the Fukagawa area near the mouth of the Sumida River (part of present Koto-ku) and the dish originally was like a fast food eaten by busy fishermen during the fishing. Fukagawa-meshi, on the other hand, is rice cooked together with asari clams. Seasonings and serving styles of Fukagawadon or -meshi vary today and their names are often confused with one another these days.
