Intro


As authentic Japanese experiences go, trying a bathhouse or onsen is right up there with eating sushi, visiting a temple or shrine, attending a sumo match, or seeing Mount Fuji with your own eyes. In other words, it’s unmissable, unforgettable, and one of the best ways to really experience Japanese culture. With more than 25,000 onsen across Japan, you have plenty to choose from too. Of course, for westerners and first-time bathers, taking off your clothes and lowering yourself into a communal onsen surrounded by strangers and other people might feel challenging or even scary. And what about the correct etiquette and rules? Do you wear a bathing costume or not? Do you shower before or after? Don’t worry - we’re here to help here at JR Pass. Simply read on to find out everything you need to know about Japanese bathing etiquette and the unique experience of visiting an onsen, plus our recommendations of potential onsen to visit during your time in Japan.

What is an Onsen?


The word onsen (温泉) describes both natural hot springs produced by Japan’s geothermal and volcanic foundations and the bathhouses that use them. While the word ‘sento’ technically describes public bathhouses, the term onsen often encompasses the full range of bathing facilities as well as hotels/inns, traditional ryokan, and spas that are built surrounding onsen. Sento on the other hand are not attached to a natural hot spring and simply use hot water, while rotenburo are outdoor onsen. However, the word onsen is often used for all three. 

Since Japan is one of the most volcanically active countries, onsen are plentiful, and there are a huge variety of different types to experience. Within larger cities, onsen are likely to be modern bath houses, but with your Japan Rail Pass in hand you can travel around the country and try everything from traditional to modern, outdoor, indoor, segregated, mixed, cedar, iron, stone or tile spas. There are onsen resort towns where you can lower yourself into warm water surrounded by snowy mountains or lush green forests - bliss! Relaxing in an onsen, solo or with family or friends, is a large part of Japanese society and has numerous benefits including pain alleviation, clearing up skin, and reducing fatigue and stress. You’ll not only be able to find one pretty much wherever you are in Japan, but each region specialises in a different mineral infused spring water, so no two onsen are the same - even more reason to travel around and try as many as you can.

A Brief History of Japanese Bathhouses and Onsen


Onsen have been a part of Japanese culture for centuries, with descriptions of hot spring baths already found in the Nihon Shoki, which dates back to the 1st Century. Japan is a series of islands - more than 6,000 in fact - and is located in the Pacific Ocean’s ‘Ring of Fire - making the country one of the most volcanically active in the world. The upside of this intense geothermal activity are naturally occurring hot springs throughout the country - there’s such an abundance in fact that there are an estimated 25,000 onsen in Japan, from outdoor hot springs to contemporary and luxurious modern day bathhouses - all taking advantage of the pure, naturally occurring hot spring water bubbling up from Japan’s geothermal core. In many ways, it’s unsurprising that onsen have become such an integral and cherished part of Japanese culture and society. Onsen are enjoyed by family and friends and it’s a great way for visitors to experience a Japanese tradition first-hand.



Essential Etiquette for Japanese Onsen


It’s time for the answers to the questions you’ve been wondering about since you started reading. What is the correct way to enjoy a Japanese onsen? What is the etiquette and how can you make sure you’re following the rules? The answer to the last question is simple - just read on and we’ll tell you. 

  • Onsen are separated by gender

The majority of Japanese onsen are segregated by gender meaning that men bathe with men and women bathe with women. While mixed onsen and private onsen for couples do exist, most are segregated so you don’t have to worry about being nude in front of the opposite sex.

  • Take off all your clothes 

There are no bathing suits required in Japanese onsen - you go in completely naked. This may feel scary for westerners who are unused to communal bathing, but in Japan it is completely natural and even a social experience. You do, however, get a small towel to cover yourself and you should use this on your way into and out of the water. You will also be required to leave your shoes at the door when entering - something common across Japan - and you may receive slippers to wear inside instead (although not in the onsen itself, of course). There are baskets and lockers for storing your clothes and belongings.

  • No phones or cameras

Onsen are not places to try and take photos for social media!   

  • Wash in the shower area before entering the onsen 

You might be surprised to discover that you wash with soap before getting into the onsen. This is to ensure your body is clean before you get into the hot spring water. There are shower areas to use, often with soap provided, before you lower yourself into the onsen. It is essential you do this before getting into the water to make sure you’re clean. 

  • No washing in the onsen

Since you wash beforehand, you don’t wash in the onsen. It’s for relaxing only. 

  • Cover any tattoos

Traditionally, tattoos have been associated with organised crime in Japan, so showing them off is a general no-no, especially at the onsen. This means checking to see whether the onsen allows tattoos before disrobing or more likely, covering them over with a skin-coloured plaster or sticker (where possible). These will sometimes be provided.

  • Don’t put your towel in the water

As we mentioned, you will be provided with a small towel for your modesty, but it’s important not to let this fall into the onsen water. It’s another no-no, and is seen as contaminating the water. Instead, place your towel safely outside of the pool or rest it on your shoulder or head (as pictured above). 

  • No alcohol 

While drinking alcohol in an onsen is forbidden, it is recommended to drink plenty of water beforehand to stay hydrated. Also, no running, shouting, or jumping into the water - this should hopefully be self-explanatory. 

  • Don’t go under the water or let your hair go in the onsen

Similar to the towel rule, it’s frowned upon to go under the water or let your hair go in the water as it’s seen as contaminating the purity of the onsen. 

  • Try the different baths

Onsen often include a range of different baths, including different temperatures and even electric baths with a low-level electric current running through them (yes, really!), so there’s definitely more than one type of onsen to experience. 

  • Relax and enjoy

With all the above etiquette observed, simply lower yourself in, relax, lie back, and enjoy one of the most authentically Japanese experiences - the onsen. Afterwards, simply towel down and get dressed - you don’t shower again after getting out of the onsen as you’d be washing away all the beneficial geothermal minerals.
