Understanding onsen etiquette is key to a relaxing and respectful experience. For foreigners, the most important rules involve hygiene, respect for shared spaces, and awareness of specific prohibitions, particularly regarding nudity and tattoos.

Why Are There Rules for Onsen?

Onsen, or hot springs, are a cherished part of Japanese culture. They are seen as places for deep relaxation, rejuvenation, and communal well-being. To maintain this peaceful atmosphere and ensure hygiene for everyone, specific rules are followed. These guidelines help preserve the tradition and ensure that both locals and visitors can enjoy the benefits of the mineral-rich waters [1, 2].

What Are the Basic Onsen Etiquette Rules?

The core of onsen etiquette revolves around cleanliness and consideration for others. Here are the fundamental practices you should follow:

Before You Even Get Wet: The Washing Ritual

This is perhaps the most crucial step. Before you enter any of the hot spring baths, you must thoroughly wash your body at the designated shower stations [3].

Nudity and What to Wear (or Not Wear)

In most public onsen, full nudity is required. Swimwear or any other clothing is generally not permitted in the bathing areas for both traditional and hygienic reasons [1, 7].

Maintaining a Peaceful Atmosphere

Onsen are sanctuaries of calm. Loud noises and disruptive behavior are frowned upon.

What About Tattoos?

This is a common concern for foreign visitors. Historically, many onsen prohibited guests with tattoos due to associations with organized crime in Japan [13]. However, attitudes are evolving, especially in tourist-friendly areas.
