Kaike Onsen for ¥450 — the everybody’s bathhouse at the entrance to the seaside spa town
Kaike Onsen, on the coast of Yonago in Tottori, is one of the San’in region’s largest spa towns, born in 1900 when fishermen found hot water bubbling up in the sea — a seaside resort with a white-sand beach and views of Mt Daisen. At the entrance to its strip of big hotels, O-yu Land is a municipal-style day bath attached to the O-yu Hotel, where locals enjoy Kaike’s source water for an everyday ¥450. Two bathhouses — the round-tub “O-buro” and the U-shaped “Yu-buro” — alternate weekly between men and women, each with a rotenburo, jets and a carbonated tub; the far-infrared and mist saunas cost ¥230 extra (¥680 including admission). The water is a sodium-calcium chloride spring, salty as befits a shore-side source, with excellent heat retention that keeps you warm long afterwards, and a reputation for helping cuts and poor circulation. Wheelchair loans, a private care bathroom and a private open-air bath make it accessible for seniors, disabled visitors and families. It is right by the “Kaike Kanko Center” bus stop, 20 minutes from Yonago Station, and 10 minutes from Yonago IC — easy to reach, and a good “one more bath” for travellers staying in Kaike as a base for Yonago Kitaro Airport (25 min), the Mizuki Shigeru Road in Sakaiminato, hiking or driving on Mt Daisen, or the Adachi Museum of Art (40 min by car). Open 10:00–23:00 (from 12:00 on the third Monday), daily apart from a few maintenance days around June. Kaike beach is the birthplace of Japanese triathlon (1981), and in summer the bath is loved for rinsing off the salt after a swim.
Tips & cautions
- 10:00–23:00 (last entry 22:30); from 12:00 on the third Monday. A few maintenance days around June — check the site.
- Sauna is +¥230 (¥680 total) — choose at reception.
- The two bathhouses alternate weekly and differ in rotenburo size, so a second visit is a different experience.
- Chloride water stings cuts and tarnishes silver; skip rinsing to stay warm longer.
- Tattoos: municipal-style facility with no confirmed policy — ask at the desk.
- Evenings are busy with locals — daytime is quieter.
- After a summer swim, shake the sand off outside before entering.
- A good post-hike soak after Mt Daisen — 10 min from Yonago IC.
