The Japanese Grand Prix (Japanese: 日本グランプリ, translit. Nihon-guranpuri) is a race in the calendar of the FIA Formula One World Championship. Historically, Japan has been one of the last races of the season, and as such the Japanese Grand Prix has been the venue for many title-deciding races, with 13 World Champions being crowned over the 30 World Championship Japanese Grands Prix that have been hosted.
The first two Formula One Japanese Grands Prix in 1976 and 1977 were held at the Fuji Speedway, before Japan was taken off the calendar. It returned in 1987 at Suzuka, which hosted the Grand Prix exclusively for 20 years and gained a reputation as one of the most challenging F1 circuits. In 1994 and 1995, Japan also hosted the Pacific Grand Prix at the TI Circuit, making Japan one of only seven countries to host more than one Grand Prix in the same season (the others being Great Britain, France, Spain, Germany, Italy and the USA). In 2007 the Grand Prix moved back to the newly redesigned Fuji Speedway. After a second race at Fuji in 2008, the race returned to Suzuka in 2009, as part of an alternating agreement between the owners of Fuji Speedway and Suzuka Circuit, perennial rivals Toyota and Honda. However, in July 2009, Toyota announced it would not host the race at Fuji Speedway in 2010 and beyond due to a downturn in the global economy, and so the Japanese Grand Prix was held at Suzuka instead. Suzuka has hosted the Japanese Grand Prix every year since 2009. Wikipedia
