SPA & Sauna

Hachikan is a private sanctuary welcoming only one party per day.
At Hachikan SPA within the accommodation wing, experience true "totonoi" (deep wellness) with world-class facilities including a Japanese cypress bath, open-air bath, dry sauna, and thermarium.

By sharpening your five senses and creating a state of stress-free, deep relaxation, it is said that constitution improvement and natural immunity reach their highest potential.

The Sovereign Experience

Faithfully recreating the ancient Roman bath tradition, Hachikan SPA effectively balances the three principles of thermal dynamics—convection, radiation, and conduction—to create an optimal environment for physical comfort and therapeutic efficacy.
By minimizing physical stress, we provide the ultimate sanctuary for your body and mind to restore their peak vitality.

Thermarium

Within Hachikan’s thermarium, three distinct thermal states are created, allowing you to experience the authentic Roman-Irish bath ritual.

Tepidarium

A gentle heat chamber kept around 38–39°C, with radiant floor, wall, and bench surfaces heated to approximately 60°C.

Caldarium

A 100% humid steam bath maintained at approximately 45°C with soothing botanical vapor.

Laconium

Intensified radiant heat on floors, walls, and benches to encourage deep, purifying perspiration.

Therapeutic Benefits

Relief for Respiratory Health

Natural deep breathing in the steam chamber helps soothe respiratory discomfort.
Moisture nourishes mucous membranes, enhanced by refreshing natural aromas.

Mind-Calming & Stress Relief

In the caldarium environment, cortisol release is suppressed in the brain, encouraging profound stress reduction and inner calm.

Skin Radiance & Clarification

Cutaneous blood vessels dilate and pores open naturally.
Perspiration aids in purifying the skin for a clear, healthy complexion.

Enhanced Natural Healing

Resting in an environment close to core body temperature reduces physical strain and maximizes innate restorative powers. Moist heat penetrates deeply to relieve muscular tension.

* When pouring aroma water for löyly, please pour from the back of the sauna stones toward the front to prevent steam burns.

* Before performing löyly, ensure the stones are sufficiently hot by testing a small amount of water to hear an active sizzle.

* Please be cautious as doors and wooden walls may become hot.

* Please refrain from excessively prolonged sauna sessions.
