Patrick Frater Asia Bureau Chief Netflix will give a May launch to “Sanctuary,” a sports drama series set in the specialized world of Japanese sumo wrestling. Produced by the Slowtide company for the streamer, the show follows a juvenile delinquent who becomes a sumo apprentice. He soon finds himself on a collision course with a voiceless wrestler carrying a secret. Netflix pitches it as “a gritty look into the underbelly of professional sumo, a world full of young men with ambitions for money, women, fame, and power […] where some may find sanctuary with a history of more than 1,500 years in Japan’s traditional culture and as a religious ceremony.”
