Sodium Chloride spring

A blend of four Shirahama wells (Tsubaki-no-yu, Kakitani No.1, Kakitani No.3, and Kanro-no-yu) yielding a hypertonic sodium chloride spring at 55.5 °C. Richly mineralized at 13.08 g/kg total dissolved solids — leaves a fine salt film on the skin after bathing. Neutral pH with a salty taste and a very faint rotten-egg note at the source; metasilicic acid is also generous at 102.6 mg/kg, lending a noticeably smooth feel.

666. Yukai Resort Shirahama Gyoen, Shirahama, Wakayama ★ Visited for higaeri on the tegate pass. Higaeri hours are 07:00-10:00 and 15:00-24:00 (last entry 22:00). Included in the Shirahama tegate (2 stickers). There is a gender rotation for baths at each higaeri time slot. There's a large lounge with lying-down areas, a minibar, and manga. Lots of people and noisy - typical Ooedo. 1. Red plum (紅梅) bath set. Available for men in the evening. Photos of baths from the internet match. A fairly weak and uninteresting set. 1.1. Outdoor bath. Half of the bath is enclosed by the building, the other half by a rock. But this doesn't create the intended atmosphere as it might look on paper - instead it feels unfinished. Clear water, temperature around 40. 1.2. Indoor area. A bit stuffy inside. 1.2.1. Bath with clear water, slight smell from the water. Temperature around 40.5. 1.2.2. Sauna. 1.2.3. Cold bath. 2. Hakubai (白梅) bath set. Available for men in the morning. A strong and interesting set. 2.1. Semi-open outdoor bath, format seems similar to Red plum, but this one turned out great. Close-up view of a huge rock with bamboo on top. The overall atmosphere is also pleasant. Clear water, temperature around 41. 2.2. Indoor area. Breathing inside is good. Photos of the bath from the internet match. 2.2.1. Bath with clear water, temperature around 42.5. 2.2.2. Sauna. 2.2.3. Cold bath. Very unbalanced bath sets: Red plum (紅梅) is forgettable, while Hakubai (白梅) is excellent and recommended. 07.11.2025 08.11.2025
