Chojukan Inn is the only Japanese-style ryokan at Hoshi Onsen. It was built 140 years ago and has been designated as national tangible cultural asset. Its huge bath shows the sign of an elaborate western-style mansion in the Meiji Era (1868-1912) called Rokumeikan Palace.
At the ryokan, there are few different types of onsen. One is where natural spring water wells up from the cobbled bottom of a huge bathtub. Many recognized writers and artists loved Hoshi Onsen. Among the most well-known were Yosano Tekkan (1873-1935) and his wife Akiko (1878-1942), Naoki Sanjugo (1891-1934), and a laureate of the Nobel Prize for Literature, Kawabata Yasunari (1899-1972).
A Japanese film director used this place for his movie, *Thermae Romae, which became a blockbuster hit. As a result, Hoshi Onsen became nationally famous.
*An ancient Roman bathhouse architect ended up in present-day Japan. He was ordered by the Emperor to build one-of-a-kind bathhouse for him. He learned state-of-the-art Japanese technology and successfully completed his project. The movie is based on a popular Japanese comic.
It's a simple hot spring of colorless and transparent calcium, sodium, and hydrosulfates (weak alkaline hypotonicity). The water temperature of the onsen is between 27 and 43 degrees C. It is said to help alleviate symptoms of Neuralgia, muscle pain, gastrointestinal disease, burns, arteriosclerosis, etc.
