Welcome to Fudoson-no-Yu Oyado Kotobuki

Kotobuki is a Japanese inn at Kanbayashi Hot Spring, which was selected as one of Japan's top 100 hot springs. At Kotobuki, you can enjoy hot spring water flowing freely direct from the source. Surrounded by a garden tended by the proprietor, you can experience a rich, green environment at Kotobuki. Situated in a secluded location, Kotobuki combines the merits of convenient access with a quiet environment. Jigokudani Monkey Park is also located nearby, making Kotobuki the perfect place to tour Nagano's famous snow monkeys. The name "Fudoson-no-Yu" is derived from the Mitakara Fudoson temple located next to the inn, where the Buddhist guardian deity Acala (known as Fudoson or Fudomyo'o in Japanese), is enshrined at the temple. "Yu" means hot water, bath, or hot spring in Japanese, and thus Fudoson-no-Yu translates roughly to "Acala's bath." Since ancient times it has been passed down that those who visit and worship Acala will be blessed with children. The name which follows, "Kotobuki," is an extremely auspicious word in Japanese, and our predecessors who established this inn chose it in the hopes that everyone who visited would become happy.
