Daigo Saito (斎藤 太吾, Saitō Daigo, 7 March 1980, Saitama) is a Japanese professional drifting driver, currently competing in the D1 Grand Prix series for ATR Radial / Monster Energy / Sunoco and Formula DRIFT USA and World Championship series for Achilles Radial. He was the first driver to win the two drifting majors, D1GP in 2008 and Formula D in 2012.
From an early age he was into motorbikes as his father was, and got his motorcycle license at 16. One night when he was out riding with his friends they stumbled upon a drift meeting in the hills of Karuizawa, there he saw a white Mercedes-Benz saloon drifting. From then on he wanted to drift himself and he wanted to drift a saloon. As soon as he was 18 he got his drivers license, his father did not want him to drift so bought him a Mini Cooper as his first car. At this time he did not know that it would not be a good car to drift so he tried, and ended up writing it off. He then bought a Nissan Silvia S13 without asking his parents and set about practicing, his first practice session lasted 36 hours only stopping for food and fuel. He learned a lot from this first practice session though he totalled the Nissan Silvia S13 a couple of weeks later.
