Japan’s hot springs are considered special not just because you can bathe in warm water. Their appeal lies in how the number of springs, the variety of waters, outdoor baths, hot spring towns, inn culture, and bathing etiquette all come together as one experience.
It is not necessary to claim they are the “best in the world,” but it is true that Japan’s hot spring experience differs greatly from bathing cultures in other countries. This article explains why, using concrete data.
Japan’s hot springs are special because several elements overlap. There are many hot spring areas, so they are easy to fit into travel plans. The range of spring waters creates distinct character. Outdoor bath culture is strong. They are tied to hot spring towns and inn culture. And cleanliness and manners help support the quality of the experience. Let’s look at each point.
Japan is one of the world’s leading volcanic countries. The Japan Meteorological Agency lists 111 active volcanoes in the country, so it is blessed with underground heat. As a result, hot springs are not limited to a few regions; they are found throughout Japan.
According to an Environment Ministry survey at the end of fiscal 2022, there were 2,879 hot spring areas with lodging facilities nationwide, and the total number of sources reached 27,932. For travelers, the key point is that hot springs are not a rare destination; they are something that can be easily built into almost any itinerary. For more on why they appear so widely, see how hot springs emerge.
Japanese hot springs are classified into 10 therapeutic spring types based on their mineral content, and each one can have a distinct color, smell, and feel on the skin.

A full overview is available in the hot spring water types guide.
In Japan, bathing is closely tied to scenery and the stay itself. Think of outdoor baths where you can enjoy snow or autumn leaves, hot spring towns where you walk around in a yukata, and staying at a ryokan with meals and hospitality included. The experience around the water is part of what it means to go to a hot spring. For famous destinations, see Japan’s famous hot springs.
Wash your body before entering, do not put towels in the bath, and keep quiet. These bathing etiquette rules help keep shared baths clean and comfortable. Even the practice of sharing a bath naked works because everyone follows the same rules (why people bathe naked). This shared code of conduct raises the overall quality of the Japanese hot spring experience.
Compared with spas and baths overseas, the features of Japanese hot springs become clearer.
| Japanese hot springs | Common overseas spa style | |
|---|---|---|
| Clothing | Nudity is standard | Swimsuits |
| Men and women | Separate by gender | Mixed use is common |
| How people spend time | Quiet soaking | Social conversation |
| Water character | Diverse spring types | Focus on temperature and facilities |
