Yakuza: Arte examines the twilight of the Japanese mafia. Supported by strong testimonies, this investigation shows how the Japanese underworld saw its supremacy waver over time.

The two 52-minute parts offer an immersion into the heart of their rituals and their contradictions. A yakuza does not touch drugs even if he controls their sale, for example. The whole thing is teeming with details which suggest the courtesy as well as the unpredictability of Michaël Prazan's interlocutors.
