History
editThe JGTC (Japanese Grand Touring Championship)[1]was established in 1993[2][3]by theJapan Automobile Federation(JAF) via its subsidiary company the GTA (GT Association), replacing the defunctAll Japan Sports Prototype ChampionshipforGroup Ccars and theJapanese Touring Car ChampionshipforGroup Atouring cars, which instead would adopt thesupertouringformula. Seeking to prevent the spiraling budgets and one-team/make domination of both series, JGTC imposed strict limits on horsepower, and heavy weight penalties on race winners in an openly stated objective to keep on-track action close with an emphasis on keeping fans happy.
In its first season, the JGTC grid mostly consisted ofJapan Super Sport Sedancars, with the only genuine JGTC cars being aNismo-enteredNissan Skyline GT-RandNissan Silvia S13,of which the GT-R was a modified AWD Group A car. An exception was the first race of the season, which was also an exhibition race of theIMSA GT Championship,and therefore saw a contingent of GTS and GTU cars from the American series join the field. The1000 km Suzukaalso saw a greater variety of competitors, with Group C prototypes,Group Ntouring cars, and GT cars from Europe and IMSA all joining the field.
For the following season, the series would undergo a rules overhaul, creating a class for theFIA'sGT1category, and another for theGT2category. The JSS series would altogether dissolve into the latter category. What made the series more significant was that compared to other racing series, JGTC teams at the time had the freedom to enter whichever cars they preferred, even if it was the JSS cars from the inaugural season or spaceframe racers from the IMSA GTS class. However, the Group C prototypes, whilst easily showing dominant form, were banned from the series from the1995 seasononwards.
By the end of the 1995 season, as the cost of obtaining and running a GT1 car had dramatically increased, the JGTC would go through another rules overhaul in order to lower costs and avoid the fate of the JSPC series it had replaced. The newly formed GT500 and GT300 regulations were adopted, which capped cars with air restrictors depending on their amount of weight and horsepower. While the regulations would continuously evolve, the GT500 and GT300 classes continue to form the top level of Japanese sports car racing today.
The cars
editThe cars are divided into two groups: GT300 and GT500. The names of the categories derive from their traditional maximum horsepower limit - in the early years of the series, GT500 cars would have no more than 500 horsepower while GT300 cars would max out at around 300 hp and have far less downforce than their GT500 counterparts. While the current generation of engines in GT500 and GT300 cars produced a horsepower output in excess of the traditional limit, the limit stayed in place throughout the entirety of the JGTC era.
In both groups, the car number is assigned to the team, in which each team is allowed to choose whichever number they want as long as the number isn't already used by any other team. The number assigned to each team is permanent, and may only change hands when the team exits the series. In addition, only defending team champions in GT500 are allowed to use number 1, although it isn't mandatory for defending champions to use that number.
For easy identification, GT500 cars run white headlight covers, windshield decals, and number panels, while GT300 cars run yellow versions of those items.

Controversies
edit1998 JGTC Fuji incident
editJapanese driverTetsuya Otais notable for surviving a fiery multi-car pileup he was involved in during a JGTC race atFuji Speedwayon May 3, 1998. The accident was initially caused by an oversaturated track. Ota then aquaplaned and left the track which put him directly into an already crashed Porsche. At the time of the accident, the Ferrari Ota was driving had a full cell of fuel which was ignited by the impact. Ota was severely injured due to third-degree burns on a good percentage of his body which may have been prevented if JGTC, at the time, had sufficient emergency response. Ota filed a lawsuit against the racing club plus organizers for negligence and won the sum of¥90 million(US$800,000).
Death of Shingo Tachi
editAlthough there are presently no fatalities during a JGTC or Super GT race meeting,Shingo Tachi,the 1998 GT300 champion, was killed during a testing accident inTI Circuit Aidaon March 11, 1999. Tachi's GT500 Toyota Supra, belonging to Team LeMans, suffered a technical failure and was unable to slow down for the first corner; Tachi crashed into the tyre wall at unabated speed, suffering massive chest injuries from the steering wheel and was pronounced dead an hour later.[4]
Champions
editMasahiko Kageyama and Morio Nitta are tied for the record of most drivers championship won in GT1/GT300 class with three.Masahiko Kageyamawas the first driver to win multiple championship as well as the sport's first two-time and three-time champion, all of them won consecutively.
