Extensive body tattoos ('body suits') are commonly worn by Yakuza members. These traditional tattoos are known as irezumi in Japanese. Their size and elaborate nature show not only the wearers' affiliation, but also his ability to endure pain.
Starting in the Kofun period (300-600 A.D.), tattoos began to assume negative connotations. Instead of being used for ritual or status purposes, tattooed marks began to be placed on criminals as a punishment (this was mirrored in ancient Rome, where slaves were known to have been tattooed with mottos such as "I am a slave who has run away from his master").
At the beginning of the Meiji period (1868-1912 A.D.) 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 and many businesses in Japan (such as public baths, fitness centers and hot springs) still ban customers with tattoos.
