All-Japan Formula Three Championship

All-Japan Formula Three Championship (全日本F3選手権), also known as Japanese Formula Three, is a national motor racing championship that takes place in Japan. It is a junior-level feeder formula that uses small single seater Formula Three chassis.

It is one of the four major Formula Three championships that guarantee the winner an FIA Super Licence.

History
The first Formula Three championship to take place in Japan was held by Nippon Formula 3 Association (Japanese Formula 3 Association) in 1979, which was won by Toshio Suzuki. By 1981, it had evolved into a national-level series, the Japanese Championship, and was organised by the Japan Automobile Federation (JAF).

Foreign drivers' participation has increased since the 1980s and the majority of champions have been foreign since the beginning of the 1990s.

Since 2008 a two-tier championship system was adopted as a bid to increase driver and team participation. The "Championship" class was open to cars conforming to the current three-year cycle, whilst the lower tier "National" class was open to cars meeting the previous three-year cycle and using the spec Toyota engine.
