In 2009, Japan's National Police Agency estimated that there were 80,900 active Yakuza, whose activities include drug dealing, extortion, illegal gambling and violent turf wars. Bound by a strict and ruthless moral code, the Yakuza are known to cut off the ends of their fingers to prove the sincerity of an apology.
Kusters put all of these incredible experiences into a limited edition book titled Odo Yakuza Tokyo, which quickly sold out. With such a great response, a second edition of the book is set to be released on October 30, 2011. Be sure to check out his website for more information.
