Kawatsura Lacquerware has been made since the 17th century using lacquer to coat bowls that had been used to coat weapons. As the industry grew, other utensils, food items, and household goods were also made as lacquerware and sold. A museum on the second floor has exhibits about the local Kawatsura Lacquerware. The first floor is a shop and showcase where you can purchase your own. They also offer lacquerware painting classes (reservations required).

川原毛地獄
Named as one of Japan's "hells" (jigoku) for its stark-white volcanic rocks and sulfide gases seeping from vents in the rocks, it was a place of ascetic worship long ago. Sanzensoji Temple was built here to worship, and like many places of ancient mountain worship, women were forbidden. Later it became a sulfur mine. Today there are walkways that allow visitors to explore the hell safely. The main walkway leads to the Jizo statue and Oyutaki Waterfall.
秋乃宮博物館
This fascinating museum is essentially a collection of historical objects. There are few explanations of what you're seeing, but most of it is rather obvious -- old records, comic books, toys, TVs, pachinko machines, etc. The museum building is an old house, and the owner often serves tea and snacks at no extra charge. There is bath in the basement, right next to the river, which also may be used at no extra charge.
