Phanfone started affecting Japan late on October 4, as it began weakening. High waves and winds of 90 mph (150 km/h) were reported most in southern Japan. At the Kadena Air Base, the typhoon killed a U.S. airman and left two others missing after they were swept out to sea. It was also reported that 10 people were injured and nearly 10,000 houses were without power. On October 5, Phanfone also affected the 2014 Japanese Grand Prix, bringing strong winds and heavy rainfall which made the track surface wet and significantly reduced visibility. Because of this, the race had to be red flagged twice; the first time because the torrential rain made conditions too treacherous to race in and the second time because of a fatal accident involving Jules Bianchi, which was partially caused by the wet track conditions.
