[Saitama Prefecture] The home of the Koropokkuru!? The ancient burial mound "Yoshimi Hyakuana"

Yoshimi Hyakuana is a mountain full of holes in Yoshimi Town, Saitama Prefecture. These holes were once the home of Koropokkuru, but after investigation, it was discovered that they were actually a group of cave tombs from the Kofun period over 1,400 years ago. They are now designated as a national historic site. Saitama is actually a kingdom of ancient tombs, but these cave tombs are rare and are said to be one of the largest in the country. The "100 holes" in Yoshimi Hyakuana means "that many," and there are actually 219 holes. During the Meiji period, a researcher from the University of Tokyo came to investigate and took home a large number of excavated items, including grave goods, which have not been returned since. The few grave goods that remain are currently on display at Osawa Shoten on the premises. It is also a place where an underground munitions factory was built during World War II. Until a few years ago, it was possible to visit inside, but a collapse was discovered in part of the passageway, and since then, it has been off-limits. The Yoshimi Hyakuana is actually privately owned, and the owner of the mountain is Mr. Osawa, the owner of Osawa Shoten. He is appealing to the national and local governments to close off only the collapsed part of the passageway and open the rest, but it is a nationally designated historic site, and due to the complicated procedures, it will take time. The underground factory is a natural air conditioner, and when you stand in front of the entrance, a cool breeze blows gently from underground. From the top of the burial mound, there is an observation deck where you can see the whole of Yoshimi Town. #Domestic travel record #Saitama Prefecture #Amazing view #B-class spot
