The Onsen Guide
What is an Onsen?
An onsen is a natural hot spring bath, central to Japanese culture for over a thousand years. Fed by geothermally heated water from volcanic activity, each onsen has unique mineral compositions offering different health benefits. The experience is about more than bathing — it's a ritual of purification, relaxation, and connection.
Types of Baths
Public Bath (Daiyokujou)
Shared bathing areas separated by gender. The traditional onsen experience where locals and guests bathe together.
Private Bath (Kashikiri)
Reserved for individuals, couples, or families. Available by reservation at most ryokans, often with stunning views.
In-Room Onsen (Rotenburo-tsuki)
Private outdoor bath attached to your room. The ultimate luxury — soak whenever you want with complete privacy.

Essential Etiquette
1. Before Entering
Remove all clothing in the changing area. Place belongings in a locker or basket.
2. Washing Station
Sit on the low stool and wash your entire body thoroughly with soap and shampoo before entering any bath.
3. In the Bath
Enter slowly. Keep your small towel out of the water (place it on your head). No swimming, diving, or loud talking.
Health Considerations
Hot spring water temperatures typically range from 38°C to 43°C (100°F to 109°F). Stay hydrated, limit soaking to 15-20 minutes, and avoid bathing if you have open wounds, high blood pressure, or are intoxicated.
