Japanese people tend to shower at night before bed, as they believe it helps them relax and sleep better. While private showers have become more common in modern Japan, public bathhouses remain popular for socializing and relaxation. Cleanliness is highly valued in Japanese culture, and specialized shower products are used to ensure thorough cleanliness. Children are encouraged to shower before bedtime as well to establish good hygiene habits. Visitors to public bathhouses should expect to bathe naked, which is an important cultural tradition promoting equality and cleanliness. Some Japanese people have started using "dry cleaning showers" that use ozone gas instead of water to kill bacteria and odors on the skin as a way to conserve water.
