An outdoor bath, known as a rotenburo, is one of the experiences many people remember most from a visit to Japan.

Japan's outdoor bathing culture is closely linked to its volcanic landscape. With thousands of natural hot springs across the country, people have been bathing in naturally heated water for centuries. Many of today's open-air baths continue that tradition, combining hot water with the surrounding landscape.

Unlike an indoor bath, a rotenburo is designed to make the outside world part of the experience. Some overlook mountains or the sea, while others are surrounded by forests, rivers or carefully designed gardens. The scenery changes with the seasons, making the same bath feel different throughout the year.

The weather is part of the experience too. A cool breeze, falling snow or even gentle rain can make the contrast with the warm water feel even more relaxing. Many people come to enjoy these moments just as much as the bath itself.

Open-air baths are found across Japan, from remote hot spring villages to modern bathhouses in the middle of cities. Wherever they are, they reflect a simple idea: bathing isn't only about the water. The surroundings matter too.

Every season changes the bath.
