Soichiro Honda decided to develop a new permanent circuit in Mie prefecture in the late 1950s. Designed as aHonda test track in 1962 by DutchmanJohn "Hans" Hugenholtz, the track has a figure-of-eight layout, with the 1.2 km (0.75 mi) long back straight passing over the front section by means of anoverpass. It is the onlyFIA Grade 1 licensed track to have such a layout, after theFiorano Circuit was downgraded to Grade 2 in 2024.[7]
The circuit has been modified at least eight times:
In 1983 achicane was inserted at the last curve to slow the cars into the pit straight; the original circuit was an extremely fast track with only one slow corner; without the Casio chicane some cars would go through the final long right-hand corner flat out and then would go past the pits at more than 200 mph (320 km/h). In 1984 the first part of Spoon was made slightly slower and the corner was brought closer to the track to expand run-off area there, and in 1985 the first corner was made slightly slower.
In 1987 the circuit was brought up to F1 and Grand Prix motorcycle standards for both Japanese Grands Prix of their respective championships, the F1 Grand Prix being the first held at Suzuka. The Degner curve was made into two corners instead of one long curve, and morecrash barriers, more run-off areas were added, exposed vegetation was barricaded off and straw bales were removed (but still used for the Japanese motorcycle Grand Prix).
In 2002, the chicane was slightly modified, 130R (marked as 15 on the diagram) was also modified and some of the snake curves were made a bit straighter and faster; additionally, the runoff area at the Dunlop Curve was doubled from 12 to 25 m (39 to 82 ft), and the corner itself was made slightly tighter.
In 2003, the chicane was made slightly faster and closer to the 130R.[8]
Following the death ofDaijiro Kato at the2003 Japanese motorcycle Grand Prix, Suzuka reconfigured the motorcycle variant of what is now known as the Hitachi Automotive Systems Chicane before the final turn, and added a second chicane, between the hairpin and 200R.[9]
The circuit can be used in five configurations; the car full circuit, the motorcycle full circuit, the "Suzuka east," "Suzuka west car," and "Suzuka west motorcycle" configurations. The "east" portion of the course consists of the pit straight to the first half of the Dunlop curve (turn seven), before leading back to the pit straight via a tight right-hander. The "west" course is made up of the other part of the full circuit, including the crossover bridge; the straight leading to the overpass is used for the start/finish line and the grid. The chicane between the hairpin and 200R separates the west and full course sections between cars and motorcycles.
The Degner curve was named in honour ofErnst Degner after he crashed his factory Suzuki 50 there during Suzuka's inaugural All Japan Championship Road Race meeting on 3 November 1962.
At the2014 Japanese Grand Prix, F1 driverJules Bianchi suffered serious injuries after colliding with a recovery vehicle, and died in hospital as a result nine months later. In the wake of the accident, theDunlop corner was slightly changed and revised in safety standards, and the organisers of the Japanese Grand Prix installed a large crane in place of the tractor that Bianchi hit.[10]
Following two major accidents in 2002 and 2003, one of the main issues in safety has been at the corner 130R. In 2002,Toyota F1 driverAllan McNish suffered a high-speed crash through the bump, which sent him through a metal fence; he was not seriously injured.[11]
Track officials revised the 130R, redesigning it as a double-apex section, one with an 85 m (279 ft) radius, and then a second featuring a 340 m (1,120 ft) radius, leading to a much closer Casio triangle (chicane), with the chicane becoming a "bus stop" type for motorcycles.
However, the problem continued for the new revised section. During the2003 MotoGP Grand Prix of Japan, the track's first major event since the revisions,MotoGP riderDaijiro 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 the incident.
Suzuka, openly touted by F1 drivers and fans as one of the most enjoyed, is also one of the oldest remaining tracks of theFormula One World Championship, and has a long history of races as venue of theJapanese Grand Prix since 1987.[12] Its traditional role as one of the last Grands Prix of the season means numerousworld championships have been decided at the track. Four years consecutively in its early history the circuit saw the world championship decided. These include the 1988 championship, which went toAyrton Senna, the controversial 1989 championship, which went toAlain Prost, and the 1990 and 1991 world championships, which both went to Senna.
Suzuka was dropped from the Formula One calendar for the2007 and2008 seasons in favour of theToyota-ownedFuji Speedway, after the latter underwent a transformation and redesign by circuit designerHermann Tilke. Suzuka and Fuji were to alternate hosting the Japanese Grand Prix from 2009. However, after Fuji announced in July 2009 that it would no longer be part of the F1 calendar,[13][14] Suzuka signed a deal to host the Japanese Grand Prix in2009,2010 and2011.[15]
The circuit closed for a year for renovations to make it F1-compliant for 2009, with the last major event held on November 18, 2007,[16] although some annual events (for example, theSuzuka 8 Hours andSuzuka 1000 km) were still held. The track held a re-opening day on April 12, 2009.

Suzuka also hosts other motorsport events including theSuzuka 1000 km endurance race. Previously a part of multipleGT racing series including the now defunctgroup C class of theAll Japan Sports Prototype Championship, the Suzuka 1000 km as of 2006 is now a points round of theSuper GT Series, and is the only race of such length in that series. In2010, the GT500 pole position time was 1:55.237. In2007, the GT300 pole position time was 2:06.838.
Another major motorsport event is the Suzuka 8 Hours for motorcycles, which has been run since 1978. This event usually attracts big name riders and with the exception of 2005, due to the importance of the major manufacturers' involvement, theFIM ensures that no motorcycle races clash on the date.
NASCAR organized theNASCAR Thunder 100, a pair of exhibition 100-lap races on the east circuit, a 2.243 km (1.394 mi) layout which utilizes the pit straight and esses, before rejoining the main circuit near the Casio triangle. The cars wereSprint Cup Series andCamping World West Series cars and the field was by invitation for the two races, run after the 1996 and 1997 seasons. The 1996 event was marred by tragedy when during practice,pace car driverElmo Langley died of a heart attack in theChevrolet Corvette pace car at the esses during an evaluation run. The pole position speed was 83.079 mph (133.703 km/h).[17] During qualifying for the 1997 race, rain caused Goodyear to userain tires on Winston Cup cars for the first time in the modern era.
It was announced on June 21, 2010, that the east section of the Suzuka Circuit would host theJapanese round of the2011 WTCC season instead of theOkayama International Circuit.[18] At the2012 event, the pole position time was 0:52.885 seconds, for an average speed of 94.875 mph (152.687 km/h).[19]

Along withFuji Speedway, the Suzuka Circuit was one of the four tracks featured in the video gamePole Position II. The track is referred to in theNamco Museum versions of the game as the "Wonder Circuit" ("Orange Circuit" inNamco Museum: Virtual Arcade), after Namco's "Wonder" series of amusement parks, despite its logo appearing on the starter's box since 1983.
Project CARS andProject CARS 2 have a Japanese circuit inspired by Suzuka, calledSakitto Circuit. Sakitto has numerous visual differences from the original Suzuka, including the change of position of the Ferris wheel near to Degner curves, as well as the absence of the Casio triangle and the hairpin, a very modified esses section, and a road pass through the real life location of the Ferris wheel.
