This article explores the debate around tattoos in onsens in Japan. Onsens are hot springs that have been popular in Japan for centuries, and they are often located near scenic areas such as mountains or rivers. Tattoos have long been taboo in Japanese culture due to their association with organized crime groups known as yakuza, so it is generally frowned upon to show them off in public places. Some believe that allowing people with tattoos into onsens would be disrespectful to those who follow traditional Japanese customs, while others argue that it should be allowed as long as people respect the rules of the establishment they are visiting. It is important for visitors from abroad to research ahead of time what type of behavior is expected from guests at each particular establishment before booking their stay there, and also to cover up any visible tattoos if necessary before entering any public space during their visit.
