Effective spring types for peripheral circulation

Peripheral circulation disorders carry a bathing indication across all 10 spring types, with those offering strong thermal and vasodilatory effects being especially suitable.

Specifically indicated for peripheral circulation; absorbed H₂S promotes vascular dilation

CO₂ absorbed through skin dilates capillaries; bubbles envelop the skin during bathing

Salt film maintains warmth after bathing, preventing post-bath chill

See the full 10-spring-type guide

Onsen minerals involved in peripheral circulation

Free carbon dioxideRead the mineral guide

Carbon dioxide absorbed through the skin widens the capillaries, promoting blood flow to the hands and feet.

Sulfide ionRead the mineral guide

Hydrogen sulfide dilates peripheral vessels and boosts circulation — the core of sulfur springs.

How 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.

Bathing tips for peripheral circulation

  1. Aim for 40–41°C for 10–15 minutes; avoid long soaks above 42°C
  2. Submerge the hands and feet fully, gently massaging or moving them while bathing
  3. Stay warm after bathing to avoid post-bath chill, and rehydrate regularly
  4. Choosing vasodilatory springs such as carbon dioxide or sulfur springs is even more effective

Gunma Kusatsu· 万代鉱1Kusatsu Onsen
The Strongest Spring from the Mine

The Bandaiko source, which unexpectedly erupted from within the Bandai Sulfur Mine in 1970, now stands as Kusatsu's primary hot spring, boasting the largest output and supporting the town. Named with the wish for 'eternal prosperity' (万代), this powerful source was born in the mountains, far from the Yubatake (Kusatsu's central hot-water field). Its colorless, transparent waters deliver a stimulating tingle that awakens both mind and body, while its robust warmth permeates to the very core. This energetic spring is a perfect companion for those seeking liberation from daily routines and a crisp mental and physical rejuvenation.
