Shibu Onsen, located in Nagano Prefecture, is a hot spring resort that has a history as long as 1,300 years. Cobblestone lanes are surrounded by traditional wooden ryokan inns, which makes this quaint old town attractive to many visitors. You will feel the atmosphere of a Japanese onsen village while strolling on these streets in your yukata (light cotton kimono) and bathing in the 9 natural onsens that run through the town.
The area is most famous for Jigokudani monkey park where wild macaques bathe in the hot springs during the winter months to avoid the cold
The best time of year to visit Shibu Onsen is December to March.
