History of Daizen.大善の歴史

Edo 江戸

The latest Uogashi (fish market) in Toysu started from early Edo era. The fishermen of Tsukuda village in Settsu moved to Edo to supply fishes for the shogun when Ieyasu Tokugawa entered Edo. The fishermen asked the Shogun to sell the remaining fishes to the people, which started Uogashi(fish market). Three fishermen who asked for permission from the Shogun were Hirayoshi Oguroya , Sonroku in Tsukuda and the founder of Daizen. The history of Daizen begun with the establishment of Uogashi.

Nihonbashi 日本橋

Uogashi in Nihonbashi was located in current Nihonbashi Honcho 1 chome. In these days, wholesalers, brokerages and retailers were trading fishes from Boushu(Chiba), Soushu(Kanagawa), Enshu (Shizuoka) and so forth. At that time, white fish such as red snapper were considered high quality while red fish were less preferred, due to storage technology. In the late 1800s, the 16th head of Daizen, Zenjiro Takarai, started to specialize in Tuna.
At that time, Tokyoite preferred light tasting red meat and were not interested in fatty tuna. In Taisho era (1912-1926), young people working at Uogashi(fish market) realized how delicious fatty tuna was. In 1922, Daizen, with a mission to promote fatty tuna, opened a tuna restaurant “Daizen Maguro(Tuna) Sushi” in Asakusa that gained in popularity.

Tsukiji 築地

Uogashi(fish market) in Nihonbashi, which continued for over 300 years, was decided to move to Tsukiji after the great Kanto earthquake in 1923. As Tsukiiji opened in 1935 to start its new chapter, Daizen also commanded popularity as a traditional Tuna merchant.

Toyosu 豊洲

Tsukiji fish market has relocated to Toyosu and so has Daizen. Daizen secures approximately 30 Tuna every day. There are 50t Tuna in its freezer at all time to respond to customers’ request anytime.
