Tokyo's "sento" public bathhouses are making an effort to become foreigner-friendly by printing multilingual brochures and posters to explain Japan's communal bathing etiquette ahead of the Tokyo Olympics in 2020.

"We know some foreign travelers have shown interest in the bathhouses as a unique aspect of Japanese culture," Katsutoshi Kuromasa, a section chief at the Tokyo Sento Association, said Friday. He added that member bathhouse operators in popular tourist spots like Asakusa in Taito Ward have recently seen more foreigners trying out the mass baths.

"We expect an increase in the number of travelers and those who would like to bathe at bathhouses as the Olympic Games come to Tokyo in 2020," said Kuromasa, who expressed hope the brochures and posters will help foreigners learn more about the cultural experience.
