Suzuka International Racing Course

The Suzuka International Racing Course (Japanese: 鈴鹿国際レーシングコース, Hepburn: Suzuka Kokusai Rēsingu Kōsu), also known as the Suzuka Circuit (鈴鹿サーキット, Suzuka Sākitto), is a 5.807 km (3.608 mi) motorsport race track located in Ino, Suzuka City, Mie Prefecture, Japan. It is operated by Honda Mobilityland, a subsidiary of Honda Motor Co., Ltd., and has a capacity of 155,000 spectators.

In the late 1950s, Soichiro Honda decided to develop a permanent circuit in Mie Prefecture. The track was designed in 1962 by Dutchman John "Hans" Hugenholtz as a Honda test track. Its distinctive figure-of-eight layout features a 1.2 km (0.75 mi) back straight that passes over the front section via an overpass. It is currently the only FIA Grade 1 licensed track to have such a configuration, following the Fiorano Circuit's downgrade to Grade 2 in 2024.

The Degner curve was named in honour of Ernst Degner after he crashed his factory Suzuki 50 there during Suzuka's inaugural All Japan Championship Road Race meeting on 3 November 1962.

The original circuit was an extremely fast track with only one slow corner; without the chicane, some cars would pass the pits at more than 200 mph (320 km/h). The circuit has been modified at least eight times:

In 1983, a chicane was inserted at the last curve to slow cars entering the pit straight. In 1984, the first part of Spoon corner was made slightly slower and brought closer to the track to expand run-off area, and in 1985 the first corner was made slightly slower. In 1987, ahead of hosting Formula One and Grand Prix motorcycle racing, the Degner curve was split into two corners, and additional crash barriers and run-off areas were added. In 2002, the chicane was slightly modified, the 130R corner was redesigned as a double-apex section with an 85 m radius first apex followed by a 340 m radius second apex, and several snake curves were straightened; the runoff area at the Dunlop Curve was doubled from 12 to 25 m (39 to 82 ft) and the corner itself was tightened. In 2003, the chicane was made slightly faster and brought closer to 130R. Following the death of Daijiro Kato at the 2003 Japanese motorcycle Grand Prix, the circuit reconfigured the motorcycle variant of the Hitachi Automotive Systems Chicane before the final turn and added a second chicane between the hairpin and 200R. In preparation for the 2025 Japanese Grand Prix, the circuit was resurfaced from Turn 1 to the entry of Turn 8.

Safety at the 130R corner has been a recurring concern. In 2002, Toyota F1 driver Allan McNish suffered a high-speed crash at the bump there, sending him through a metal fence; he was not seriously injured. Track officials responded by redesigning 130R as the double-apex section described above. However, the problem continued: during the 2003 MotoGP Grand Prix of Japan, MotoGP rider Daijiro Kato was killed when he crashed in the new section on his way to the braking zone for the Casio triangle. MotoGP has not returned to Suzuka since that incident.

At the 2014 Japanese Grand Prix, F1 driver Jules Bianchi suffered serious injuries after colliding with a recovery vehicle; he died in hospital nine months later. Following the accident, the Dunlop corner was revised in safety standards and a crane was installed in place of the tractor that Bianchi had struck.

Suzuka hosted its first Formula One Grand Prix in 1987 and has served as the venue of the Japanese Grand Prix since that year. Its traditional position late in the calendar means numerous world championships have been decided at the circuit. Four consecutive championships were settled at Suzuka in its early years: the 1988 title went to Ayrton Senna, the 1989 title controversially to Alain Prost, and the 1990 and 1991 titles both to Senna again.

Suzuka was dropped from the Formula One calendar for the 2007 and 2008 seasons in favour of the Toyota-owned Fuji Speedway, redesigned by circuit designer Hermann Tilke. The two circuits were intended to alternate hosting the Japanese Grand Prix from 2009, but after Fuji announced in July 2009 that it would no longer be part of the F1 calendar, Suzuka signed deals to host the event in 2009, 2010, and 2011. The circuit closed for a year for renovations to become F1-compliant for 2009; the last major event before closure was held on 18 November 2007, though some annual events such as the Suzuka 8 Hours and Suzuka 1000 km continued. The circuit reopened on 12 April 2009.

As of March 2026, the official lap record for the current circuit layout is 1:30.965, set by Andrea Kimi Antonelli during the 2025 Japanese Grand Prix. The unofficial lap record is 1:26.983, set by Max Verstappen during qualifying for the same event.

Suzuka hosts a range of motorsport events beyond Formula One. The Suzuka 1000 km endurance race is a points round of the Super GT Series and the only race of such length in that series. The Suzuka 8 Hours motorcycle endurance race has been run since 1978 and usually attracts prominent riders; the FIM ensures no motorcycle races clash with the date.

NASCAR organised the NASCAR Thunder 100 exhibition races on the east circuit (a 2.243 km layout) after the 1996 and 1997 seasons. The 1996 event was marred when pace car driver Elmo Langley died of a heart attack at the esses during an evaluation run. During qualifying for the 1997 race, rain caused Goodyear to use rain tyres on Winston Cup cars for the first time in the modern era.

The east section hosted the Japanese round of the 2011 WTCC season. The circuit also hosts the Ferrari Challenge Japan, Porsche Carrera Cup Japan, the Super Formula Championship, and the FIM Endurance World Championship Suzuka 8 Hours.

Along with Fuji Speedway, the Suzuka Circuit was one of four tracks featured in the arcade game Pole Position II. It also appears in the Final Lap series, the motorcycle game Suzuka 8 Hours (1992 arcade, 1993 Super NES port), and numerous titles including the Gran Turismo series, Forza series, iRacing, RaceRoom, Le Mans 24 Hours, MotoGP 3, and Continental Circus. The east course featured in NASCAR 98. The circuit has been modded into Mario Kart Wii.

Project CARS and Project CARS 2 include a Japanese circuit inspired by Suzuka called Sakitto Circuit, which differs from the original in several respects including the position of the Ferris wheel, the absence of the Casio triangle and hairpin, and a modified esses section.
