Your guide to experiencing Japan's bath culture

温泉

What is an onsen?

温泉 (Onsen) are natural hot spring baths that have been an integral part of Japanese culture for centuries. These natural hot springs are heated geothermally and often rich in minerals, which are believed to have therapeutic benefits.

Quick Overview:

  • Natural hot spring water with minerals and specific temperature.
  • Temperature typically 40-44°C (104-111°F)
  • Different types of bath for various health benefits
  • Many onsens are located to ryokan (traditional Japanese inns)

Onsen culture & history

Onsens (温泉) have been a cornerstone of Japanese culture for over a thousand years, deeply tied to the country’s volcanic landscape and natural healing practices. The word "onsen" literally means hot spring, and Japan has over 3,000 of them due to its location along the Pacific Ring of Fire.

In ancient times, onsens were more than just places to bathe—they were sacred spaces. Buddhist monks and Shinto practitioners believed that the mineral-rich waters had purifying properties, both physical and spiritual. Some temples even developed around hot springs, turning them into pilgrimage sites.

Choosing the right onsen destination

The perfect onsen experience begins with choosing the right location. Not all onsens are the same—some are located deep in mountain villages, while others are near big cities or scenic coasts. Here are a few tips to help you choose the perfect spot based on your preferences:

Decide the atmosphere you want

  • Traditional & Quiet: Opt for a rural onsen town like Kurokawa or Ginzan.
  • Scenic Views: Head to places like Hakone (Mt. Fuji views) or Nyuto (snowy forests).
  • Urban Convenience: Try easily accessible spots like Odaiba or Ikaho.

Consider the water type

Each region’s water has unique minerals. For example:

  • Sulfur-rich: Good for skin and joints (e.g., Kusatsu, Beppu)
  • Iron-rich: Warming and energizing (e.g., Yamagata)
  • Salt-rich: Moisturizing and good for circulation (e.g., coastal onsens)

Match with other activities

  • Ski + Soak: Combine skiing and onsen in places like Nozawa Onsen or Zao Onsen.
  • Cultural Sites: Choose areas like Kyoto or Nikko with both history and baths.
  • Nature & Hiking: Opt for mountainous regions like Nagano or Gifu.

Check accessibility

  • Is it reachable by train? Do you need to rent a car?
  • Look for regions with good transport links if you’re on a short trip.
