At the beginning of the Meiji period the Japanese government, wanting to protect its image and make a good impression on the West, outlawed tattoos, and irezumi took on connotations of criminality. Nevertheless, fascinated foreigners went to Japan seeking the skills of tattoo artists, and traditional tattooing continued underground.
Tattooing was legalized by the occupation forces in 1945, but has retained its image of criminality. For many years, traditional Japanese tattoos were associated with the yakuza, Japan's notorious mafia, and many businesses in Japan (such as public baths, fitness centers and hot springs) still ban customers with tattoos.
Tattooing and other forms of body decoration and body modification, as in much of the western world, are gaining in popularity in Japan. However, Japanese young people who choose to get tattooed are most often choosing "one point" designs—small designs that can be completed in one sitting—usually in the American or tribal styles. More recently, however sanskrit Siddham script tattoos are becoming more and more fashionable. (source: http://en. wikipedia.org)
