Amazing holes dug into a mountain! A national historical site with tunnel tombs.
Yoshimi Hyakuana is a tunnel tomb created in the late Tumulus period (late 6th century - late 7th century). In 1923, it was designated as a national historical site.
The current count of confirmed tunnels is 219. These tunnel tombs were made by digging slopes of hills and plateaus. The structure of the main part where the dead was laid is almost the same with the tunnel stone rooms in the late Tumulus period. The whole area of Hyakuana stands on the bedrock called tuffaceous sandstone. It is said that people back then must have looked for spots suited for digging.
Another attraction is Hikarigoke (Glowing Moss). The fantastical green moss is often found in mountains. The kind that grows in Kanto Valley is an extremely valuable plant and designated as a national natural treasure in 1928.
On the premises, you can view the town’s valuable national treasures displayed at Yoshimi Town Buried Cultural Property. You can have a hands-on experience, making beads and clay dolls.
Yoshimi Town is famous for Udon noodles. After touring Yoshimi Hyakuana, stop by one of the many noodle shops.
