Takanoyu Onsen

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.

This natural outdoor hot spring is a short walk from the road parking lot and Jizo Statue below Kawarage Jigoku. Bring a swimsuit.

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.

A scenic gorge with a walking path that winds past 98 °C hot spring waters emitting steam. There is a red bridge overlooking offering a view from above. It's particularly popular in the fall when the autumn foliage is in full effect.

The museum outlines the history of the Innai Silver Mines, which was the top producer of silver in its heyday, with videos, pictures, and artifacts from the mines and miners. They also have a small collection of ancient pottery excavated from around the area. The building is a German-style brick building. The other part of the building is used as Innai Station.

A castle ruled by the Onodera Clan until the area was overtaken by the Mogami Clan. The castle has exhibits about the local history and culture.Unique among Japanese castles, you can ride a slopecar to reach the castle. Alternatively there is a walking path.
