Shionoe Onsen: Hot Spring Guide & Visitor Access

At the southernmost edge of Takamatsu, this mountain hot spring bubbles up in a valley of the Sanuki range. Said to have been opened by the Nara-period monk Gyoki and later visited by Kobo Daishi, it has long been cherished as a place of healing waters. Its soft, sulfur-bearing water is a defining trait.

Highlights

Wooden bridges and footbaths dot the banks of a clear stream, framed by gentle countryside scenery. Wrapped in valley breezes and the murmur of the river, its quiet lets visitors forget the bustle of the city. Beside Gyoki Bridge stands a day-trip bath named Gyoki no Yu.

Enjoying the Seasons

Spring brings fresh greenery and mountain cherry blossoms, summer offers fireflies, autumn colors the valley in red and gold, and winter dusts the hamlet in snow. Riverside walks pair naturally with a round of the baths.

Access and Basic Information

It lies about forty minutes by car south of central Takamatsu along Route 193, and about ten minutes by car from Takamatsu Airport. Kotoden buses also serve the area, and the Shionoe roadside station makes a handy base for sightseeing.

Practical Travel Notes

The resort holds several inns as well as a day-trip bath, Gyoki no Yu, near the Shionoe roadside station, so you can enjoy it on a stay or as a stopover. Day-trip bathing fees start from the few-hundred-yen range as a guide, and hours and closing days differ by facility. There is also a free footbath to drop by during a stroll. The water is described as a soft, sulfur-bearing spring that warms the body from within. Fees and hours at each facility can change, so confirm before visiting to be sure.

A Quick Tip

Mornings and evenings turn chilly in the mountains, so bring an extra layer and enjoy a stroll after your bath. With a free footbath on hand, pair it with a riverside walk if you have time.
