This long-standing store has been plying its trade for around 140 years, selling seafood-paste products such as kamaboko (steamed and seasoned fish paste), hanpen (a pounded fish cake) and date-maki (a rolled omelette mixed with fish paste) from two Tsukiji locations. Find its first store, Tsukugon Ichiba-bashi, facing Shin-Ohashi-dori, while its second, the Tsukugon Monzeki-bashi shop, looks out over Higashi-dori.
UPDATE: Tsukugon closed permanently at the end of June 2017.
