Jozankei Dam is a great sightseeing spot. Completed in 1989 and measuring at 117 metres, it offers fantastic views over Lake Sapporo and  down the river in which it feeds into. Not only does Jozankei Dam have great views, but it also has  a museum that is free to enter. The museum displays diorama models of the dams construction, has historical pictures and panels of the local area, and videos and exhibits detailing the electricity system. You will need access to your own transport to get there, though if you are a bit more adventurous, its a good walk from the central onsen district of Jozankei.

There is plenty of parking at the dam if you are driving. There is a trail that leads down to the bottom of the dam which makes for a pleasant walk through the trees and park areas. It makes for a great spot for a picnic, a spot of lunch or to view the autumn leaves in season. The trail to Mt. Kotengu can also be found here. The whole area of Jozankei is nice spot to drive or walk around. While in the area, there is not only Jozankei dam, but also the  Ainu Culture Museum, Hakkenzan Winery, Nishiki bridge, as well as all the Onsens!
