Kamasaki Onsen is a historic hot spring resort in Shiroishi, Miyagi Prefecture, in the Tohoku region of northern Japan. With a history dating back more than 600 years to 1428, it is considered one of the region’s long-established hot spring destinations.
For centuries, Kamasaki Onsen has been known as a traditional healing hot spring, or toji resort, where people visited for extended stays to relax and recover through bathing. It was traditionally nicknamed “Kamasaki for wounds”, reflecting the belief that its mineral-rich waters were beneficial for wounds and burns.
According to local legend, the hot spring was discovered by a farmer who was cutting grass. When he dug into the ground with the tip of his sickle, hot water reportedly sprang from the earth. This story is said to be the origin of the name “Kamasaki,” which literally refers to the tip of a sickle.
Kamasaki Onsen has long been valued for its therapeutic bathing tradition. The waters were traditionally believed to be helpful for wounds and burns, as well as conditions such as nerve pain, rheumatism, digestive problems and other ailments.
Because of its reputation as a healing hot spring, Kamasaki Onsen is said to have attracted historical figures including Date Masamune and Katakura Kagetsuna. During its long history, the area became a popular destination for people seeking the restorative benefits of hot-spring bathing.
Today, Kamasaki Onsen continues to preserve this traditional atmosphere while welcoming visitors looking for a peaceful escape in the mountains of Miyagi.
The hot spring water at Kamasaki Onsen is classified as a sodium-chloride-sulfate spring containing iron. The source temperatures are approximately 39°C to 47°C, providing a relatively mild and comfortable bathing experience.
The water is known for its smooth texture and gently warming sensation. Historically referred to as a “medicinal hot spring”, Kamasaki Onsen has been appreciated for relaxation and recovery from fatigue. Visitors can enjoy a traditional Japanese bathing experience while surrounded by the quiet atmosphere of the hot spring town.
Kamasaki Onsen once had numerous traditional inns that accommodated visitors staying for toji, the Japanese custom of spending several days or longer at a hot spring for rest and recovery. Today, the compact hot spring town is home to five atmospheric traditional inns, each offering its own character and hospitality.
The buildings and streets retain traces of an earlier era, creating a calm atmosphere that is quite different from large modern hot spring resorts. Staying overnight allows visitors to experience not only the hot spring itself but also the traditional rhythm of a Japanese onsen town.
Yushua Ichijo is regarded as the oldest long-established inn in Kamasaki Onsen. Its wooden buildings, including architecture dating from the Taisho era, preserve the atmosphere of traditional Japan.
For international visitors interested in Japanese architecture, history and traditional hospitality, the inn provides an opportunity to experience the atmosphere of a historic ryokan while enjoying the hot springs.
Mogamiya Ryokan was established during the Edo period and occupies a central place in the history and atmosphere of Kamasaki Onsen.
Suzukiya Ryokan is known for its distinctive bathing facilities, including a golden-colored bath, as well as meals traditionally served in guests’ rooms.
Kimuraya Ryokan has been known for its cloudy hot spring water and its distinctive “Tengu Bath.” The inn is currently closed, so visitors should check its latest operating status before planning a visit.
Tokine no Yado Yushua Ichijo is the oldest traditional inn in the hot spring town and is particularly notable for its historic wooden architecture.
Shiki no Yado Michinoku-an offers an atmosphere closely connected with the surrounding natural environment. Its open-air bath is one of the highlights for guests who want to enjoy hot-spring bathing surrounded by greenery.

A shared parking area is also available near the hot spring town, making it convenient for visitors traveling by car.
The surrounding area is blessed with the natural beauty of the Southern Zao Mountains. Fresh green foliage can be enjoyed in spring, colorful leaves create beautiful scenery in autumn, and snow-covered landscapes give the area a quiet winter atmosphere.
These seasonal changes make Kamasaki Onsen an attractive destination throughout the year. Visitors can combine a relaxing bath with walks through the surrounding natural landscape and sightseeing in the wider Shiroishi and Zao areas.
From Shiroishi-Zao Station on the Tohoku Shinkansen, Kamasaki Onsen can be reached by bus in approximately 20 minutes. This makes the hot spring town relatively convenient for travelers arriving from Sendai, Tokyo and other major cities by high-speed train.
