The very beginning of a Tokyo Market dates back to the days of Tokugawa Ieyasu when heopened Edo government; he brought in the fishermen from Tsukuda, Osaka City to Edo to let them purvey seafood's to Edo castle, and at the same time gave them permission to sell the remains near the Nihonbashi bridge. The vegetable and fruit markets also developed spontaneously around the same period. After the Meiji Restoration. These markets dwindled under drastic social changes, and under the new Tokyo City Government, private markets were permitted to open, which contributed to the stable supply of daily food necessary for the residents.
However, through the experiences of Rice Riots attributable to rice shortage in social unrest in 1918, the “Central Wholesale Market Law”was enacted in March 1923, which became the governing law for the opening of the public markets nationwide. While the construction plan of the Central Wholesale Markets in Tokyo was under consideration, the Great Kanto Earthquake occurred in September of the same year, and the private markets then operating suffered devastating damages. The implementation of the construction plan was accelerated, and three Central Wholesale Markets Tsukiji, Kanda and Koto were established in 1935, and then Ebara, Toshima, Adachi, and Shokuniku market were opened one by one in succession.
After WWII. The great changes in environment surrounding the markets with the high growth of the Japanese economy, and concentration of urban population in Tokyo in the late 1960s and 70s, resulted the revision of the Law into the current Wholesale Market Law, in April 1971. Under this new law, Tokyo Metropolitan Government opened markets, Itabashi, Setagaya, Kita-Adachi, Tama New Town, Kasai, Ohta. For opening of Flower markets, the flower market section was opened in 1988 at Kita-Adachi market for the first time, and then opened in Ohta, Itabashi, Kasai Markets.
Tokyo Metropolitan Government will move forward the market administration policy from the point of view of the citizens as consumers with an aim to realize comfortable Metropolitan life.
