1000 km Suzuka
The race was previously part of the All Japan Sports Prototype Championship (now Super GT) and later of the World Sportscar Championship before these series were cancelled. After that the race has become part of many different series including the Super Taikyu endurance series. In 2006, the race was integrated for the first time in the Super GT calendar. Previously, the race was open to JGTC/Super GT cars, but with only a handful of competitors from the Super GT entering.
Within years, some race length change occurs; the 2009 Super GT race was shortened to 700 km as a countermeasure of increasing cost and CO
2 emissions regulations, partly due to the economic crisis. The 700 km distance was retained in 2010, but as a result of the 2011 Tōhoku earthquake and tsunami and Super GT rule changes for that season to conserve energy that year, the race was cut to 500km. For 2012, the race returned to being a 1000 km event.
One driver holds the record of four event wins: Kunimitsu Takahashi (1973, 1984, 1985, 1989).
