During the Edo period, Nihonbashi had a place called Hon-Odawara-cho. It's near the current Muromachi Sanchome. Why was a town named Odawara in Edo built? Tsukiji still has a place name called "Tsukiji Police Station Odawaracho Koban". When I looked up with the question, "Why is there without Odawara-cho?", I arrived at the Izu stone quarry. I write it as a series of 2 times.

There is a theory that the name of "Odawara-cho" in Nihonbashi Kitazume originated from the fact that the town's name was Odawara's mason Zenzaemon worshiped the area as a stone Ageba (a place where the stones transported by boat were unloaded). There is a moat, but I don't think there was enough space to unload large stones. Probably, it is expected that the actual unloading the stone was "Kamakura Riverside" or the Funairi Canal of Kaedegawa. The Momiji River, which was a moat between outer moat and Kaede River, now a highway, was filled for use several decades after its opening.
A fish market (Nihonbashi Fish Bank) was opened in Odawara-cho, and masonry moved to Tsukiji and called Minami-Odawara-cho? Tsukiji is certainly located south of Nihonbashi. As a result, "Odawara-cho" in Nihonbashi Kitazume was renamed "Honodawara-cho".
The stone wall of Edo Castle has an inscription equivalent to the crests of various daimyo, but where was the stone mined and where was the engraved?
In Keicho 8 (1603), Ieyasu Tokugawa opened the Shogunate in Edo and performed a large-scale renovation of "Edo Castle". This construction was ordered by the daimyo of the nations, and was continued for about 30 years from Keicho 9 (1604) to Kanei 13 (1636), Ieyasu, Hidetada, and Iemitsu. At this time, the stone used for the stone wall was cut out from Izu Peninsula. We mined andesite stone from the vicinity of Manazuru and Nebukawa. It is hard to weather and excels in fire resistance. From the mountains on the Izu Peninsula, which leads from Atami to Izuinatori, tuff-based stones were mined. Tuff-based stones were not only fire-resistant, but also had the advantage of being easy to process and carry.
The trace that cut out the stone wall is called the "Edo Castle Ishichoba Site", and the Ishichoba of Odawara City, Atami City and Ito City is recognized as a "nationally designated historic site". The ruins are hidden in the woods. There is "Usami Edo Castle Ishichoba Ruins" in the mountains of Usami Gakuen, Chuo Ward, which accepts dozens of elementary school students in Chuo-ku every year. In this archeological site, there are countless "Edo Castle Tsukiishi", which was processed for use in stone walls. There are many engraved "engravings" such as the daimyo's family crest, and they have just been transported to Edo. The castle stones cut out and processed in the mountains are placed on a sled called "Shura" (pictured below), and are pulled by many hands to the coast. It is boarded from the coast to "Ishifune" and transported through Sagami Bay to Edo, but when there were many, 3,000 stone boats came and went between Edo and Izu a month.
The ruins of Ishichoba by the daimyo Tadaoki Hosokawa of Kyushu are located on Mt. Nako in Usami. It is said that the name of Mt. Nako comes from the fact that the environment of the masonry is very bad and the mason "cry". I crossed (I was weak, not a tread, but a guide from the Ito City Tourism Association pulled downhill. Finally, I will show you a photo taken in the mountains next time, but since it is an unimaginable environment such as a convenience store or a downtown area, I can imagine "crying" = Nakou . Some of the castle stones that were transported to the coast could not be loaded on stone boats for some reason and could not be transported to Edo. On the entire coast of Usami, many stones with "Yaanaishi" and "engraving" are soaked in water or buried in sand.
According to the "Todaiki" (Kanei era (1624-44)), the price of stone is equivalent to "20 silver stones with 100 people", so the early Keicho era silver (161g) is almost 1 gold If you assume one car, one stone will be less than 2 million yen. It was a great burden for the daimyo.
It's not easy to carry stone-cut stones.
I came down the mountain path as shown in the photo below. Even in a mountain of about 350m, it was difficult to go on the "road without roads" where stones rolled and pieces of wood rolled. Please look forward to it.
After mid-October, we are planning to challenge the "Edo Castle Ishigaki Ishichoba Ruins (Usami, Ito City)" again.
