Japan is the home country of tattoos, but it is also the only one where they are seen very badly: that's why.
Some think it's a legend, then they go to Japan and clash with raw reality: it is true, tattoo are frowned upon and that's why.
In Japan, anyone with tattoos is considered a Yakuza affiliate
Well, actually it's all true. Although the Land of the Rising Sun is the home of the rotary tattoo machine and has even given birth to a particular style of design - Irezumi - within its borders people with tattoos are ill-considered. The reasons are rooted hundreds of years ago. The tattoos, in fact, were used to identify the people who had been guilty of crimes: these were branded on the forehead with the word "dog" to be recognizable in the crowd.
But it was then that the Yakuza - at the time a group of gamblers - began to tattoo the whole body. The tattoos were made mainly by members of criminal and illegal associations, so that in 1900 the government decided to prohibit these designs on the body. The law was then withdrawn, but even today tattoos are seen very negatively by the population.
Yet, to avoid any kind of problem, in most public baths (once used by Yakuza as a basis for discussing their business) it is forbidden to enter any person with tattoos.
Did you think this was just an urban legend? But no.
