SOURCE
Sodium bicarbonate springs are known for softening the skin and leaving it smooth — a quality especially noticeable in the high-altitude, often foggy air of Sengokuhara.
All three baths at Sanrakuso draw from the same source. The outdoor bath faces the pampas; the indoor bath is sheltered and warm; the private bath is yours alone. Same water, different moods.
