Belgian photographer Anton Kusters has spent two years with one of Japan's notorious Yakuza gangs, known for their brutality, tattoos and strict code of honor. Taken into their confidence after months of tough negotiations, he was allowed to document their world and daily routine. This has resulted in a fascinating reportage, published in various magazine as well as in a book form, titled Odo Yakuza Tokyo (the entire edition of 500 copies has sold out in less than 2 months).
