It’s long been an unspoken rule among Japanese spa operators that customers with tattoos were not allowed into hot springs — onsens. In Japan, tattoos are associated with the Japanese mafia, commonly referred to as the yakuza. A report published last year found that 56% of hotels and inns surveyed across Japan did not allow those with tattoos to enter public baths.
"We don’t put up ’no tattoo’ signs, but we do ask them to refrain from using our baths if their tattoos cover large parts of their bodies and can’t be concealed by a sticker," a manager at Yamagishi Ryokan said, "we treat locals with tattoos the same way we treat foreigners."
However, now the Japan Tourism Agency has asked for the rules to be relaxed for foreigners as visitor numbers to the country continue to rise. An official is hoping that onsens will take into consideration the cultural backgrounds of tattooed customers and not turn them away out of fear.
The agency said that there are often religious, cultural, aesthetic or other choices behind the body modification practice and the ink doesn’t pollute the baths.
