Water and bathing details for Hakone Onsen
Facility-level figures; blank town-wide averages are not inferred.
Named facility records for Hakone Onsen. Figures marked “Not published” are not treated as town-wide averages.
| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Hakone Ginyu | Sodium chloride spring, low in dissolved solids, mildly alkaline, and high-temperature, according to the official site. Source: Miyanoshita Onsen at Hakone Ginyu. Access differs between guest-room open-air baths, the public baths, and the spa. | Source temperature: Not published pH: Not published | Guest-room open-air baths and the public baths are available to guests. The private spring bath at Ginyu Spa is limited to guests booking the relevant spa treatment; it is not included with every stay. | Ryokan. Worth comparing if the valley view is a priority. If consistent cleanliness and well-maintained facilities matter most, read recent reviews for the same room type before deciding. |
| Hakone Yuryo | Alkaline simple hot spring (low-salinity, high-temperature spring). Source: Tonosawa Onsen, a blend of Yumoto sources No. 58, 75 and 87. | Source temperature: 43.5°C for the blended spring; this is source temperature. pH: pH 9.0. | The operator describes a combination of source flow and circulation. Water may be added when visitor numbers or an urgent pool refill leave insufficient supply. Circulation maintains bathing temperature, and filtration with chlorine-based disinfection is used for hygiene. Bath additives are not used. | Day-use bath. A convenient all-in-one stop near Hakone-Yumoto for a bath, sauna, meal, rest area and private open-air bath. Its spring management combines source flow with circulation, unlike Tenzan's approach. |
| Tenzan at Tenzan Toji-kyo | A mix of alkaline simple spring and sodium chloride spring; the pools vary by source. Source: Seven nearby sources: blended sources No. 92, 93, 101, 102 and 114, plus Yumoto sources No. 74 and 115. | Source temperature: All seven sources are hot; the hottest is about 83°C. This is the highest source temperature, not a bath temperature. pH: Varies by source. Yumoto source No. 74 is pH 9.3; that value does not represent every spring or pool. | Pipelines carry water directly from the seven source locations to the baths. The operator says the high-temperature water is cooled with a heat-exchange system rather than by adding water. Flow and delivery temperature are adjusted seasonally. Every bath is drained nightly, cleaned and refilled with fresh water by morning. | Day-use bath. For visitors willing to travel a little farther from Hakone-Yumoto for the volume of the springs, water cooled without dilution, nightly bath changes and a quieter setting. The focus is on the water itself, not station convenience or private family baths. |
