Shikabe Onsen Shika no Yu

Analysis Unverified
鹿部温泉 鹿の湯
The Deer-Found Seaside Spring

The Shika no Yu source of Shikabe Onsen is said to have been discovered in the Kanbun era, when Ito Gengoro, who came from Tsugaru to harvest kelp, spotted a deer healing its wounds in the water. Once welling up naturally on the beach, this source still gushes at 77.5°C from beneath the fishing port. Its soft water, carrying a faint saltiness and a hint of the sea, wraps the skin and warms the body to the core, suiting travelers who wish to unwind slowly by Uchiura Bay.

BATHING TIPS
AI Generated

With a neutral pH of 6.9 the water is gentle on the skin, yet as a chloride spring it heats the body well, so begin with about five minutes and take breaks between soaks. Avoid rinsing too thoroughly afterward to keep the warming saline film.

EFFECT STORY
AI Generated

With 740.0 mg/kg of chloride forming a saline film on the skin, this spring offers restorative warmth long after bathing. Its 642.0 mg/kg of sulfate is traditionally associated with helping relieve pain, suiting days of chill or stiffness and bodies tired from long journeys.

CAUTIONS
AI Generated

Mind the bath temperature and avoid lightheadedness from long soaks; those with heart or blood-pressure concerns should keep baths short.
