関金温泉 せきがね湯命館
A day bathing facility at Sekigane Onsen, a 1,300-year-old spa in the hills of Kurayoshi near the Tottori–Okayama border. Once known as the 'platinum bath', its clear radium (radioactive) spring is said to be among the richest in Japan and leaves skin soft. Men's and women's indoor and open-air areas offer eight kinds of tubs, and the outdoor bath looks across ridges running toward Mt. Daisen. Adults pay ¥820, elementary pupils ¥410 and small children enter free. Open 10:00–21:00 (last entry 20:30), closed Mondays (next day if a holiday). On site are the Shirogane dining room using local produce, a free tatami hall, paid private rooms (¥1,580 for two hours), massage and beauty treatments, and free parking for 100 cars. From JR Kurayoshi Station take the Sekigane-bound bus about 35 minutes to Sekigane Onsen and walk 5 minutes, or drive about 40 minutes from Yubara IC on the Yonago Expressway via Route 313. Pair it with the cliff temple Nageiredō on Mt. Mitoku, Kurayoshi's white-walled storehouses or the Hiruzen highlands.

A 1,300-year-old radium spring across eight tubs
Sekigane Yūmeikan is a day-use bathing facility in Sekigane, Kurayoshi, Tottori, standing in a mountain hollow of the Chūgoku range near the border with Okayama. Sekigane Onsen is a spa said to have been opened 1,300 years ago, and its colourless, transparent water earned it the name 'the platinum bath' long ago. The water is a simple radioactive spring (hypotonic, weakly alkaline) — a radium spring — held to have one of the highest radon contents in Japan, and people come for the way the skin turns moist and the body feels light afterwards, some for gout, arteriosclerosis or high blood pressure. The baths come in two kinds, a rock-bath type and a wood-bath type, and they swap between men and women each week, so seeing one side does not reveal the whole facility. Between them there are eight kinds of tub — a pounding-water bath, a bubble bath, a lukewarm tub, a lying-down tub, a plunge, a sauna and a large rotenburo — and the calm, wood-scented bathhouse and the dramatic rock bathhouse are clearly different in atmosphere, so many people visit twice. From the rotenburo you look over ranges running toward Mt. Daisen, and in winter the snow-covered Chūgoku mountains are especially fine. The side facilities are substantial too: a free large hall for resting, paid private rooms (¥1,580 for two hours, ¥530 per extra hour) that suit families and groups, and recovery equipment such as bodywork, esthetic, a hyperbaric oxygen capsule and an organic germanium bath. The restaurant 'Shirogane Shokudō' serves dishes of local ingredients, so bathing and eating can be done in one place. Rates are ¥820 for adults and ¥410 for elementary pupils (¥510/¥260 for Kurayoshi residents), hours 10 a.m. to 9 p.m. (last entry 8:30 p.m.), closed Mondays (the next day if a holiday). With Mitokusan's Nageire-dō, the white-walled storehouse streets of Kurayoshi and the Hiruzen highlands nearby, it is a convenient base for touring San'in and the Chūgoku mountains.
Circuiting two bathhouses, with meals and rest
Enter from the free car park (100 spaces) and pay (¥820). Shampoo and body soap are free and lockers with keys are free; face towels cost ¥160 to buy and bath towels ¥200 to rent. A recommended circuit: wash and soak 10 minutes in the main tub; take the lukewarm tub at length — with a radium spring it is better to stay in gently and long; let the pounding water work on your shoulders; 15 minutes in the bubble bath and the lying-down tub; 8–10 minutes in the sauna and a minute in the plunge; then 15 minutes in the large rotenburo looking at the ranges. The heart of this facility is its two bathhouses: the rock-bath type and the wood-bath type swap between men and women each week, so if the rock bath is your side today it will be the wood bath next time. The atmospheres are utterly different, which is why many come twice; on a first visit ask at the desk which side is the men's today. Afterwards rest in the free large hall, or, for families and groups, hire a private room (¥1,580 for two hours) and lie down. On days when the body feels heavy add bodywork, esthetic or the hyperbaric oxygen capsule, and eat a meal of local ingredients in 'Shirogane Shokudō' to fill the day. Notes: closed Mondays (the next day if a holiday); last entry 20:30; towels charged separately; weekend afternoons are crowded; bring cash. Note that Tottori's official tourism site lists 10:00–22:00 (until 21:00 in winter from 7 January to 28 February) and closures on the second and fourth Mondays, so if you plan a late visit or one around a Monday, confirming by phone is the safe move.
