1- Misasa Onsen (三朝温泉), Tottori

The name "Misasa" (literally "three mornings") originates from the belief that one who stays to enjoy three mornings in the town's famous hot springs will find all of their illnesses cured. Misasa Onsen is a great place to rest after an intense day of hiking Mt.Mitoku nearby. While Mt.Mitoku is a difficult climb and as such doesn't allow solo hikers for safety reasons, Kurayoshi city on the other side with its rows of Shirakabe Warehouses may be more preferable for someone looking for a more relaxed day.
There are many ryokans, most of them located next to the river passing through town. Izanro Iwasaki is the most popular one, I'm guessing because of its big nice garden, but they also claim to have hosted the royal family.
How to get there: Take a bus from Kurayoshi Station (倉吉駅) until Misasa Onsen Tourism Information Center (三朝温泉観光商工センター前). It takes about 20 minutes. Here's a timetable for weekdays and weekends. If you're staying in a ryokan of the area, some may offer free shuttle service.
2- Yunokawa Onsen (湯の川温泉), Shimane
I chose Yunokawa Onsen because it's very easy to get to and has an interesting legend behind it. Yakami Hime was a beautiful princess in the land of Inaba, now western Tottori. Okuninushi and his 80 brothers were all travelling together from their home country of Izumo to court her, Okuninushi was in charge of carrying all of their luggage. On a beach they discover a hurt rabbit, and the brothers are cruel to it. When Okuninushi arrives, lagging far behind, he helps the rabbit and, seeing his kindness, Yakami Hime falls in love with him and they get married. His brothers were all furious and later got him killed, Okuninushi fell in love with the daughter of Susanoo in the underworld and went through many difficult trials to finally be together, but that's a different story! It's said that Yakami Hime bathed at this onsen, it's also one of the "Three onsens of beauty" so it's popular among women.
How to get there: walkable from Shobara Station on the Sanin Line, between Izumo and Matsue.
3- Yuki Onsen (湯来温泉), Hiroshima

4- Yubara Onsen (湯原温泉), Okayama
