After Ieyasu Tokugawa's entry into the prefecture, the flow from Hirakawa was changed, the Hibiya inlet was reclaimed, and the Dosan moat was drilled to create the Nihonbashi River.
The riverbank that was built on both banks of the Nihonbashi River is the prototype of the fish market.
Yokkaichi, which was located at the mouth of the former Hirakawa River, will also be moved here.

After that, this market prospered, and at that time, the people who contributed greatly were fishermen from the former Tsukuda Village in Osaka.
Along with entering Edo, Ieyasu will invite 30 fishermen from Settsu Tsukuda Village, who had been friends for a long time, Magoemon Mori, to catch fish in Edo Bay and give it to the castle.
In Osaka, the technology to catch fish was excellent, and fishermen in Tsukuda were able to catch a large amount of fish at Edo Bay at once.
The remaining fish will be sold to townspeople in Odawara-cho, the north side of the Nihonbashi River, in 1613 (1613).
After that, residents of Osaka moved one after another, and in 1641 (1641), there were 14 fish wholesalers.
From the castle, sometimes there are orders for 5,000 sea breams a day, but at that time, the fish caught are watered on a large ship, put in a cage to meet the demand from the castle.
After that, stick gestures (Note 1) came to buy the fish and others and sold them in the town.
The stick gesture and a kind of doorboard that runs between the wholesaler were placed on the banks, fish were placed on the banks, and they were sold in a stick gesture, but the doorboard was called a board boat, and the right to use It will be traded as board boat right (very expensive).
Even now, many of the companies on the riverbank named "Tsukuda Whats" are from Tsukuda Island.
In addition, some Tsukiji contractors protect curtains for more than 400 years.
Note: Stick-handling to sell a balance stick. Stand between a fish wholesaler and a restaurant to do business.
I'll continue next week.
