Oscar-winning composer, pioneer of electronic music, environmental activist and one of the most important artists of our era, Ryuichi Sakamoto's prolific career spans over four decades. From techno-pop stardom to film composing ('The Revetiant', 'The Last Emperor', 'Merry Christmas Mr. Lawrence' and 'The Sheltering Sky'), the evolution of his music has coincided with his own life journeys. Following the Fukushima power station disaster, Sakamoto became an iconic figure in Japan's social movement against nuclear power and in 2014 he discovered he had throat cancer. This intimate documentary follows his return to music after his illness, as his haunting awareness of life leads to a resounding new musical masterpiece. 'Ryuichi Sakamoto: Coda' is both a portrait of this wonderful musician as an artist and a man, and a look into the creative process itself.
