Take a bath in onsen hot springs
Onsen, the Japanese term for a hot spring, is central to much of Japanese culture. Numerous hot springs exist in Japan as a result of the country's volcanic activity; the Japanese frequently visit these hot springs to unwind.
The area around Nikko, at the base of Mount Fuji, then to the west of Shikoku Island, as well as the hot springs in Hakone, is where you'll find the majority of the onsen in Japan. Moreover, Kinosaki, a town close to Kyoto, is home to one of the most well-known onsens.
Anyone with a tattoo is not allowed to enter the public onsen. However, the admission ban law for tattoos is frequently waived in private guesthouses, or Ryokan.
Visit the onsen if you like to unwind in water that gets as hot as 40 degrees Celsius (104 degrees Fahrenheit). Remember that you should only sit in the warm water for around 10 minutes before taking a break.
In addition to offering a space to take off your clothing, changing rooms frequently contain shelves, baskets, and lockers where you can keep your stuff while you take a shower. There might also be a sink and a few extras, such a hair dryer or tissue. You may also find coin lockers or safe boxes where you can keep your valuables in a more secure location.
