Hyotan Onsen

**Bath circuit strategy:** Start with the falls bath (taki-yu) while your body is fresh — the waterfall pressure is intense and requires stamina. Progress to regular hot bath, then lukewarm bath, then finish with steam sauna or sand bath. The sequence prevents overheating. **Sand bath indoor version:** Hyotan's sand bath is indoors (unlike Shoningahama beach version) and smaller — only 4 people at a time. Less atmospheric than beach sand baths but more private. Book sand bath time at front desk on entry; popular times (11:00–14:00) may have 30-minute waits. **Repeat bathing:** The ¥800 entry allows unlimited re-entry on the same day if you keep your wristband. Some visitors do morning bath, leave for sightseeing, return for evening bath — maximizing the single admission price.
