On May 24, I visited the stone quarry in Usami, Ito City again. I had the opportunity to talk with the guides of the Ito City Tourism Association and obtained new information. I would like to report on this in the near future. This time, I checked where the stone walls that had been transported to Edo by Ishifune were taken in and how they were transported to Edo Castle, so I would like to explain. This is a sequel to the previously reported “Ito City Nakoyama Stone Cut Field Visit”.

The current Yaesu-dori is filled with the Momiji River dug in the east-west direction in the form of going straight to Sotobori-dori St. (river), and the intersection of Chuo-dori (Ginza-dori) and the Momiji River is Bridgestone Building and Chushoyu Building. In the Edo period, there was Nakahashi, and after reclamation, Kabuki hut was opened as Nakahashi Hirokoji Temple. There were as many as 10 Funairi moats between Kaedegawa and the outer moat, but they were made to unload the megaliths for the construction of Edo Castle. At the time of the opening of Tokugawa, this area was the sea, and if there was high-quality civil engineering technology, a pier would have been built from the coast to the shallow offshore, but in order to unload the megaliths, we had to deal with such boat excavation. There was no crane truck, so the stone with a hundred people had to be moved horizontally from the deck of the ship, so Funairi moat was built to Edo Castle.

Most Funairi moats were dug up to outer moat like the Momiji River, but it is presumed that some of them were connected to Marunouchi. This Funairi moat was issued by the Tokugawa Shogunate in 1604 (Keicho 9), and the following orders were issued to the daimyo of Nishikuni.

①Construction of 3,000 Stone and Steel Ships

②The size of the ship is large enough to carry one hundred stones from the east coast of Izu Peninsula.

③Transport operations include two round trips a month.

It was like that.
