Why go
- Rotenburo over Sagami Bay
- Hilltop among mandarin groves
- Drinkable spring water
Tiered open-air baths above Sagami Bay — 430,000 litres a day of free-flowing private spring
Yutoro Sagasawa-no-yu is a day spa on the hill at Yoshihama in southern Yugawara, near the plum-blossom mecca of Makuyama Park, proud of its private source pumped from 1,100 m below ground at 430,000 litres a day and run undiluted. Two bath halls that exploit the slope, “Otaki-no-yu” and “Kawaburo”, alternate daily between men and women; each climbs from an indoor bath and sauna through tiered open-air pools where water tumbles like a waterfall, and the top tier overlooks Sagami Bay and the Manazuru peninsula — a “sea-view onsen” quite unlike Yugawara’s valley spa street. The water is an alkaline simple spring, pH 8.4 and 44.8 °C, clear and soft in the “beauty bath” tradition, with temperature set purely by flow rather than dilution. The building, nearly 30 years old, is dated and reviewers grumble about restaurant and entry prices, yet the water and views still score highly. Closed Thursdays (open daily in plum season, February–March, and in August); recent reviews say cash only, so come prepared.
Tips & cautions
- Closed Thursdays (open on holidays and in February, March and August) and on 31 Dec–1 Jan. Last entry one hour before closing.
- Recent reviews say cash only — don’t rely on cards or QR; no ATM nearby.
- About one bus an hour — check the return timetable first.
- Tiered rotenburo means stairs — slippery; take care with elderly bathers.
- Halls alternate daily; many say “Otaki-no-yu” has the better view — ask which is men’s/women’s.
- Bring the 10 % coupon from the official site.
- Tattoo policy unconfirmed — phone ahead (0465-63-5111).
