A hot spring facility standing on the highlands of Kuroshio Town in the Hata area, rich with the bounty of the Kuroshio Current. Located overlooking the sea of Saga, known for pole-and-line bonito fishing, it is cherished as a locally loved day bath. Famous as one of Shikoku's most strongly alkaline springs, it draws visitors from afar in search of its silky "beauty bath."

Highlights

From the scenic bath, you can gaze over the Pacific spreading blue and the sun setting in the distance. The open bath, soaked in while watching the horizon, is exceptional, letting you spend a relaxing moment unique to the tropics with the sea breeze on your skin. The simple sulfur spring, one of Shikoku's most strongly alkaline at pH 9.4, has a silky feel that leaves the skin smooth, and the moisturized skin after a bath is well regarded.

Seasonal Enjoyment

From spring into summer, the shining sea and rich seafood; in autumn and winter, the sunset viewed under clear air are the charms. Being able to savor the local seared bonito is also a way to enjoy this area unique to it. At dusk especially, the moment of watching the sun set over the Pacific from the bath is a spectacle carved deep into the memory of the trip.

Access & Basic Information

It is located in Kobushinokawa, Kuroshio Town, Hata District, Kochi Prefecture. It is a few minutes by car from Tosa-Saga Station on the Tosa Kuroshio Railway, or about two hours by car from central Kochi City. It operates mainly for day bathing and has an attached dining area. As services may change with renovation, confirming before your visit is reassuring.

One Piece of Advice

A trip that makes the most of the Kuroshio sea, combined with the nearby Sunabi Museum of Sand and whale watching, is recommended. Bonito dishes are a must-eat.

Tosasaga Onsen Kobushinosato introduced in this article, its hilltop location in Kuroshio Town overlooking the sea of Saga known for pole-and-line bonito fishing, and the nearby Sand Beach Museum and whale watching are organized based on tourism information published by Kuroshio Town and the town tourism association, and information from the facility. The spring quality, such as a strongly alkaline simple sulfur spring of pH 9.4 ranking among the top in Shikoku, and the guideline day-use fees and reception hours draw on public information. Because operations may change with renewal, please confirm the facility official information before you visit.

Visitor Checklist

  • Time estimate: A short time for a bath alone, or about half a day combined with nearby sightseeing.
  • What to prepare: Bring a towel for day-use bathing. If aiming for the sunset, look up the sunset time in advance for peace of mind.
  • Best timing: A shining sea and sea fare from spring to summer, and a sunset view under clear air in autumn and winter. Dusk, gazing at the sun setting into the Pacific from the bath, is exquisite.
