Keiunkan lies at the foot of the
Akaishi Mountains. Since its founding, the
onsen has had all its hot water sourced directly from the local Hakuho Springs. The onsen was created by Fujiwara no Mahito, son of an aide to the
38th Emperor of Japan,
Emperor Tenji. The springs gained popularity and attracted bathers from various parts of Japan. The onsen's guests included
Takeda Shingen,
Tokugawa Ieyasu, and the reigning
Emperor of Japan,
Naruhito. In 2017, no family members were willing to take over the business. Keiunkan's general manager, Kenjiro Kawano, was selected as the new president. Because Kawano was unrelated to the owner he was unable to inherit Yushima, the holding company. Ownership of Keiunkan was transferred to a new holding company, Nishiyama Onsen Keiunkan Limited, and Yushima was dissolved. == Description ==
