As the trend of ‘wellness travel’ continues to gain momentum heading into 2026, the dream of taking a restorative dip to one of Japan’s steamy, dreamy Onsen towns (hot springs) has further rocketed the destination up countless bucket lists.
However, there’s a little more to it than just packing your most plush towel and cannonballing into the tub. Japan has strict rules around its bathing culture that may, at first, seem complicated to newcomers. Here is a quick guide to get you bathing like a pro.
Choosing the Right Bath for You
Often, attention is focused on Onsen, the mineral-rich, natural hot springs that some visitors might associate with Japan’s famous bathing monkeys. In contrast, the Sento is far more ubiquitous: these public bathhouses can be found in almost every neighbourhood, and come with their own traditions. If you have visible tattoos, you may be turned away! Many hot springs prohibit entry to those with tattoos, because it is redolent of yakuza, and may make others feel unsafe. However, many local Sento will readily welcome you. If you’re ever unsure, check before you go.
Onsen 101
Ready to relax? Though it might seem redundant to some, guests are expected to bathe thoroughly in a shower before entering the bath. This makes perfect sense, and is something that should be expected in the west, but is somehow...not. It shows respect for the other guests. The Japanese way ensures higher standards of hygiene and sanitation. With a small bench, bucket of hot water, soap and shampoo, guests must wash, wash, wash until clean enough to enter the sacred mineral baths. Patrons with long hair should tie it carefully before entering the water.
Japanese hot springs require quiet humility and respect.
Concerned about Privacy?
It should, of course, be noted that most facilities have separate baths for male and female patrons, and almost none allow bathers to wear swimsuits.
If, for any reason, you prefer to bathing alone, look for private charter baths, called kashikiri. If you’re staying at a traditional Ryokan, you might just find that your room has its own ensuite bath.
