Peripheral Circulation Disorders & Onsen | All 10 Spring Types Indicated

Published May 6, 2026·1min read

Peripheral circulation disorders — poor blood flow to the extremities — carry a general bathing indication across all 10 Japanese spring types recognised by the Ministry of the Environment. Thermal dilation of peripheral blood vessels is the core mechanism, with sulfur springs (hydrogen sulfide type) additionally holding a specific type indication.

Why onsen bathing improves peripheral circulation

Peripheral circulation disorder occurs when capillary blood flow to the hands and feet is reduced. The thermal effect of onsen bathing dilates peripheral blood vessels through the skin, improving blood flow. This effect is common to all spring types and is included in the general indications recognised by Japan's Ministry of the Environment.

Particularly effective spring types

  • Sulfur springs (H₂S type): Specifically indicated for peripheral circulation; absorbed H₂S promotes vascular dilation
  • Carbon dioxide springs: CO₂ absorbed through skin dilates capillaries; bubbles envelop the skin during bathing
  • Chloride springs: Salt film maintains warmth after bathing, preventing post-bath chill

Hot Springs for Cold Sensitivity | 4 Spring Types Explained

Discover which hot spring types are officially indicated for cold sensitivity and peripheral circulatory disorders, based on Japan's Ministry of the Environment guidelines. Chloride springs form a heat-retaining salt film on the skin, while carbon dioxide springs dilate blood vessels directly through the skin without stressing the heart.

Sulphur Springs: Milky White Waters with Powerful Skin Benefits

Sulphur springs contain total sulphur at 2 mg/kg or more. Their signature milky-white color and boiled-egg aroma (hydrogen sulphide) are icons of Japanese onsen culture. Indicated for atopic dermatitis, plaque psoriasis, and chronic eczema. The hydrogen sulphide type also helps peripheral circulatory failure.
