Choju Onsen is a relatively small facility, but it has been around for a long time, so I get the impression that most of its customers are elderly people. As a result, it has a homely atmosphere, and you can enjoy interacting with the locals. This hot spring is perfect for those who want to spend a relaxing time.
Although the price is low and it is popular, there are no facilities such as soap, shampoo, and hair dryers, so you will need to bring your own.
It's about a 5-minute drive from Watausagi, making it an easy hot spring to stop by.
