In the Japanese criminal gangs, members cut off their pinkie finger in a ritual called “yubitsume” whenever they have made a serious offense to the gang. Many former Yakuza members have a difficult time finding jobs due to the social stigma surrounding the gang.
A prosthetic expert in Japan creates silicone finger extensions for former Yakuza members. The price for the pinkie extension is $3,000. The expert makes about 20 to 30 fingers for former Yakuza members each year.
