An astonishing collection of tunnel tombs carved into a hillside and designated a National Historic Site.
Yoshimi Hyakuana is a group of tunnel tombs built during the late Kofun period, from the late 6th to the late 7th century. The site was designated a National Historic Site in 1923.
A total of 219 tunnel tombs have been identified. These tombs were excavated into the slopes of hills and plateaus, and their burial chambers are structured much like the corridor-style stone chambers found in burial mounds from the late Kofun period.
The area around Yoshimi Hyakuana lies on a bedrock formation known as tuffaceous sandstone. It is believed that people at the time chose this location because the rock was suitable for excavating tunnel tombs.
Another highlight is the luminous moss. This moss appears to give off an ethereal green glow and is generally found in mountainous areas. Its presence on the Kanto Plain is extremely valuable in terms of plant distribution. The habitat was also designated a National Natural Monument in 1928.
The Yoshimi Town Archaeological Center on the grounds displays valuable cultural artifacts found within the town. Visitors can also try making magatama beads and haniwa clay figures.
Yoshimi is also known for its udon and has many udon restaurants, so consider stopping by one before or after visiting Yoshimi Hyakuana.
Spring is recommended, when the cherry blossoms are at their best.
