What Is an Onsen?
An Onsen is a Japanese term that translates to “hot spa” in English. It refers to a specific type of hot spring that occurs naturally due to thousands of years of underground volcanic activity. These hot springs are heated by geothermal reactions from underground magma. While most Onsens are naturally heated, there are some that use artificial heating methods.
According to Japanese law, an Onsen must be heated to more than 25°C to be officially classified as such. These hot springs are traditionally believed to have healing properties, and some are advertised for specific needs based on their mineral composition. People visit Onsens to alleviate symptoms of muscle pain, arthritis, skin conditions, and diabetes. The healing effects are attributed to the naturally occurring minerals present in the water.
Unique Features of Japanese Onsens
Abundance of Hot Springs in Japan
Japan has many hot springs because of the volcanic mountains all over the country. In the past, these hot springs were used as public bathhouses. Today, onsen are popular tourist destinations for both foreign visitors and many Japanese. Onsens can usually be found in rural areas, where they provide an escape from the city and family responsibilities.
Recognizing Japan’s Onsen Symbols
If you’re looking for an onsen, look for the kanji symbol “湯” (pronounced “yu”), which means hot water. Sometimes you’ll see the hiragana symbol “ゆ” (also pronounced “yu”) instead, which makes it easier for younger people and foreigners to recognise onsen locations.
The Evolution of Gender
In the past, men and women used to bathe together in onsen. But during the Meiji period, when Japan began to welcome Western visitors, onsen with separate areas for men and women were introduced. You can still find some mixed-gender onsen, but most onsen today have separate facilities for men and women.
Varieties of Japanese Onsens
Onsens can come in all different sizes and settings.
Public Run Baths:
Some Onsens are small, publicly operated baths.
Hotel and Ryokan Resorts:
Many Onsens are part of hotels or traditional Japanese inns (ryokans). They may be indoors, enclosed, sheltered, or remain outdoors in their natural state.
Etiquette and Proper Manners
Pre-Bathing Ritual: Before entering the hot spring, guests should wash and rinse their bodies at designated bathing stations equipped with stools, toiletries, and shower facilities.
Naked Bathing: Bathers are not allowed to wear swimsuits in an Onsen. While some modernized Onsens permit towels or swimsuits, this is an exception. Guests should become accustomed to bathing without clothes.
Towel Usage: Towels can be used for modesty when moving between wash stations and bathing facilities. However, they should not be used in the water to avoid contamination.
Hair and Face Care: Tie up long hair to prevent it from falling into the water. Avoid putting your head or face in the Onsen.
No Intoxication: Do not drink alcohol or be intoxicated while bathing.
Hygiene and Respect: Maintain cleanliness, respect other bathers, and keep noise levels low.
Entering the Water: Be cautious when entering the hot water, as it will be very hot. It’s advisable to enter slowly.
Stay Hydrated: After bathing, rehydrate, as prolonged exposure to high-temperature water can lead to dehydration.
