If you’re planning a trip to Japan, there’s one experience that truly captures the spirit of the country: bathing in an onsen.
These traditional hot springs are not just about relaxation. They’re deeply tied to Japanese culture, wellness, and everyday life.

Whether you visit one during winter snowfall or after a long travel day, an onsen experience stays with you.

In Japanese, onsen means hot spring.
But it’s not just hot water.

Onsen water comes from natural geothermal sources and is rich in minerals like sulfur, calcium, and magnesium. Each composition is believed to offer different benefits for the body.

There are two main types you’ll encounter:

Indoor onsen
Usually found inside ryokan or hotels. Calm, warm, and comfortable.

Rotenburo
Open-air baths surrounded by nature. Forests, mountains, rivers, or snow in winter.

Health and relaxation benefits

Depending on the minerals, onsen bathing is believed to help:

• Ease muscle and joint pain

• Improve blood circulation

• Calm skin irritation

• Reduce stress and improve sleep

A ritual, not just a bath

Onsen are about slowing down.
Before entering the bath, you wash your body completely at a shower station. This step is essential and shows respect for others.

Once inside, you soak quietly. No rushing. No distractions.

A deep cultural tradition

People have used onsen for centuries.
Samurai, monks, travelers, and villagers all bathed in hot springs for recovery and well-being.

Many onsen towns still carry this timeless atmosphere.

Immersed in nature

Rotenburo are one of the most memorable parts of Japanese travel.
Soaking in warm water while surrounded by trees, mountains, or falling snow creates a strong sense of calm and connection.

Solo or shared moments

Onsen can be social or personal.
Some people go with friends or family. Others enjoy complete silence alone.

Either way, it’s a moment to disconnect from screens and daily stress.

To enjoy the experience smoothly:

• Wash thoroughly before entering

• No swimsuits, bathing is done nude

• Keep voices low

• Tattoos may be restricted in some places, check in advance or ask for cover stickers

Following these rules makes the experience comfortable for everyone.
