The 6 Hours of Fuji (formerly the Fuji 1000 Kilometres) is a sports car race held at Fuji Speedway in Oyama, Shizuoka, Japan. The race was held for the first time in 1967 and in 1977 became part of the new Fuji Long Distance Series. In 1982 a second 1000 km race known as WEC in Japan was run as a round of the World Sportscar Championship. The All Japan Sports Prototype Championship was formed in 1983, and since then co-sanctioned this event. The World Championship left after 1988, but the JSPC carried on both races until 1992. The race was revived in 1999 as an attempt to gauge interest in an Asian Le Mans Series that never materialized. The race was revived again as a part of the short-lived Japan Le Mans Challenge in 2007. The race returned again as part of the 2012 FIA World Endurance Championship season, but changed to a 6-hour race, with no distance limit.
