Heda Stone Quarry 戸田石丁場

The Heda Stone Quarry was the third such stone quarry I visited in the Izu area. It is located on the Western side of Izu, so you would think that the stone would have been used for the building of Sunpu Castle, but it was actually a quarry for Edo Castle. The boats carrying stone had to travel all the way around the Izu Peninsula to get up to Tokyo. Some of the Heda specific kokuin carvings (such as a square with a circle containing the number 7) have been found at the Sakurada and Shimizu Gates of Edo Castle. Also, the family crest of Hosokawa can be spotted around the Hirakawa and Shimizu Gates. From the writing and family crests that were found carved into stones at this site, we know that at least three daimyo, Hosokawa, Nabeshima, and Matsuura, quarried stone here. In particular the Hosokawa and Nabeshima were charged with supplying stone for the walls of Edo Castle in 1606 and 1614

Like the others, the Heda stone quarry is not on any map, nor are there any materials available to guide you around the ruins. The mountain is quite steep, a bit treacherous, and there are no trails so I would not recommend someone who is not familiar with the area to go without a guide. Heda was by far the most fascinating stone quarry I've seen so far. The kokuin and writings carved in stone are more varied and the scale of untouched ruins scattered around the mountain is impressive. There are areas where the stone has been mostly cut away making some relatively even open spaces. There are paths where dozens, if not hundreds, of stones were transported along them cutting ridges into the ground. There are also areas of steep valleys where many many stones are piled on top of each other. It looks like a dumping ground or a place where the smaller stones were piled up to be transported away. This is a really interesting area so I hope the town will develop it a little to make it at least a little bit more accessible to the average castle fanatic.
