Top Tips

– On entry to an onsen, you’re going to have to prepare yourself for your nostrils to be filled with the smell of sulfur. Don’t worry, you’ll get used to the smell quickly and won’t notice it too much after a few minutes in the baths.

– In many of the ancient onsens, complete nudity is mandatory, so get ready to bare all. Remember, however, to be respectful and not stare or behave unnaturally in the onsen.

– You’ll have to scrub your body in the shower before entering an onsen.

– Some of the onsens feel very hot at first, but you will acclimatize to the temperature of the water quickly.

– Your hair is not supposed to touch the water, so just submerge your body to your shoulders. If you have long hair bring a supply of hairbands.

– Bathhouses are social places and many bathers enjoy having a chat while relaxing. Keep voices low, however.

– Drink plenty of water before and after your visit — the heat will certainly dehydrate you.
