Oku-Mino / Gujo Hachiman奥美濃・郡上八幡

Amazing stalactites that turn red and pink. Gujo-odori, a dance that continues for 32 nights in summer.

Located almost right in the central part of Gifu, Oku-Mino's center is Gujo Hachiman, where the upper stream of the Nagara-gawa River and its branch, the Yoshida-gawa River, meet. Oku-Mino prospered as a castle town during the 16th century and even today preserves old streets defined by special lattice, "Bengara-goshi." The current castle was rebuilt in the early 20th century and in the donjon are many weapons and armor that were used in the old days.

Soso-sui Spring, or the precious water that springs out, at the foot of Shimizu-bashi Bridge over the Odara-gawa River, found near the center of town, is known as one of the best waters in Japan. On the southern side of the central district is Otaki Stalactite Cavern, about 700 meters long and 100 meters high. Inside the cavern is a big 30-meter waterfall that is said to be the largest underground waterfall in Japan. Must-see attractions here include the rare stalactites that turn red and pink, which you cannot see anywhere else.

In summer, people enjoy Gujo-odori, a dance that continues for 32 nights. The four days of the climax are called the All-Night Dance, and tourists join in the dancing from 8 p.m. to 4 a.m. the next morning.
