Essential Steps Before Bathing

  1. Hydrate (one glass of water)

    Drink a glass of water (approx. 200 ml) before entering. Avoid alcohol or caffeinated beverages beforehand.

  2. Rinse with a ladle (kakeyuu) — feet first

    Pour hot spring water over your feet, then knees, hips, and shoulders to gradually acclimate your body and prevent sudden blood pressure changes.

  3. Check your physical condition

    If you have a fever, feel unwell, or have consumed alcohol, skip the bath and rest instead.

  4. Secure your valuables

    Store wallets, phones, and jewellery in a locker before entering the bathing area.

When to Skip Bathing Altogether

  • Fever or acute illness
  • Immediately after eating (wait at least 30 minutes)
  • Right after intense exercise
  • Early or late pregnancy
  • Known contraindications for the spring type
