The Legend of Hayataro
The Sacred Dog Behind the Name
The name Hayataro Onsen comes from the famous legend of Hayataro, the sacred dog, associated with the historic Kozenji Temple in Komagane.
According to the legend, a mysterious monster was terrorizing the people of Mitsuke in Totomi Province, in what is now Iwata City, Shizuoka Prefecture. Hayataro, a dog kept at Kozenji Temple, is said to have confronted and defeated the monster, protecting the local people.
Hayataro has continued to be remembered as a symbol of courage and loyalty, and Kozenji Temple has a grave dedicated to the legendary sacred dog.
The hot spring itself has no direct connection with the sacred dog. Rather, the name was chosen to reflect Hayataro’s importance as a symbol of Komagane’s local culture and traditional legends.

Hayataro Onsen is conveniently located for travelers arriving by car. It takes approximately 5 minutes by car from the Komagane Interchange on the Chuo Expressway, making the resort particularly accessible from other parts of Japan.
By public transportation, take the Ina Bus Komagatake Ropeway Line from either JR Komagane Station or the Komagane Bus Terminal. Get off at Suganodai, from where the hot spring area is easily reached.
