Can You Wear A Swimsuit In An Onsen?

Can you wear a swimsuit in an onsen? There are no swimsuit rules in the onsen, as you must get in naked.

This is to preserve the cleanliness and hygiene of the water as you’d be sharing the same bath with other guests.

So, questions like what to wear in Japanese onsen or what to wear in an onsen are off the table. 

Having any clothes on could contaminate the water due to the bacteria in them.

A small and a big towel will be given when you are using an onsen (sometimes you need to bring your own or purchase one).

The small towel is the modesty towel that is given to cover your body for privacy when you’re moving about the onsen, as well as to wipe yourself up after soaking before entering the dressing room and drying yourself up. 

While you are in the bath, you can place the small towel on top of your head like many Japanese do. 

Onsen baths are known for it’s benefits for the skin; hence you will reap most of the benefits when your skin is exposed to the water. 

However, the good news is, some onsens allow you to wear swimsuits. We will look into the list as you read this article! 

How Hot Is An Onsen?

The usual temperature of an onsen is 39 degrees Celsius to 42 degrees Celsius. However, it can vary from one onsen to another.

It is a good idea to always check with the specific onsen for their water temperature.

What To Wear To An Onsen?

There’s no such thing as an onsen bathing suit, so you don’t have to think about what do you wear in an onsen. You will need to wear your birthday suit before entering the bath. 

Can You Bring A Camera To An Onsen?

I LOVE taking pictures of my trips! Unfortunately, photography is not allowed in an onsen.

I’m sure you like to take pictures, too, but keep your phones and cameras away when you’re in an Onsen because you don’t want to be seen as a pervert who likes to take pictures of naked people 😅

This rule applies to most of the onsens in Japan. You will be asked to leave your smartphones and cameras behind.

Most onsen comes with a changing room where you will remove your clothes, jewelry, and other belongings. 

You are either given a basket or a locker ( with a fee) to keep your belongings safely. 

Personal tip 1: If you want to take a picture to keep as memories or for your blog, you may want to check with the staff at the reception to ask for their permission.

Can You Visit An Onsen With Tattoos?

Visitors with tattoos are not allowed in Japan’s onsens because they are associated with Japan’s criminal underworld. 

However, you might see this rule overlooked in touristy areas to accommodate tattoo tourists. 

Can Babies/Children Visit An Onsen?

Even though there are no age limits for using an onsen, babies, and toddlers are not allowed in the tubs in some onsens.

It is unsuitable for babies because they are in diapers, and the rule is to keep the water hygienic and clean. 

However, if the kid is old enough to take a bath on their own, most onsens are gender-segregated, and kids can accompany either one of their parents to enjoy their baths. 

As parents, you need to check if the onsen will be suitable for your kids as the temperature and water types might not be suitable for their age.
