Japanese Manufacturers in Sportscar Racing
It's probably a little unfair to lump all the Japanese manufacturers together, but I don't claim to know a lot about them, especially their domestic racing, where sportscar racing is possibly the biggest form of motor racing.
Undoubtedly, the driving force in Japanese involvement in sportscar racing is a desire to win Le Mans.
There is a Japanese GT series website.
Mazda - Winners of Le Mans 1991
Mazda led the way in World Sportscar racing by bringing one of their rotary engined cars to Le Mans. They've since become a well established presence at Le Mans and are, to date, the only Japanese maker to take that much valued win. Mazda claim that showroom sales increased by 30% after their 1991 win; remarkable, if true.
In 2008, Mazda added a class win in GT at Daytona to their impressive record.
Up against works Pontiacs and a phalanx of Porsche 911s, an RX-8 (four door, four seater design, albeit a spaceframe one in race form) took the class win.
Nissan - Top dog in the US.
Nissan have also been a frequent competitor at Le Mans and during the heydays of Group C. After dominating the IMSA series in the 80s, they moved over to the Group C series with a sleek, Lola built car, powered by an excellent V8 twin turbo engine. On many occassions the cars looked like outside bets for victory, but they proved a little fragile and the wins eluded them, both in the World Endurance Championship and at Le Mans.
In 1997, they returned to Sportscar racing in a big way with a TWR designed 'GT' powered by that Group C V8. In testing they were fast, but late changes to the cars (supposedly due to late clarification of the rules), led to gearbox problems, despite showing well in the early stages.
In 2010, Nissan returned to sportscar racing with a GT1 version of their GTR model.
Whilst the road car featured a V6 turbo engine, a 5 lite V8 was selected for the racer.
Toyota - Staunch supporters of the WEC
Like Nissan, Toyota were regular competitors in the Group C days, with their V8 powered cars. They also struggled onto the end of the Group C days with a 3.5 litre V10 engined car, which came close to winning Le Mans a couple of times, once against the Peugeots and once against the Dauer-Porsche 962 'GT' car.
They also dabbled with a Supra in GT spec, but despite being highly competitive in the Japanese GT series, it proved overweight and ill-balanced at Le Mans.
The team returned in the late 1990s with the near Group C Toyota GT-ONE.
It ran at Le Mans twice, in 1998 and 1999
In 1999 the lone GT-ONE was closing down on the leading BMW prototype in the closing stages only to suffer a puncture and be forced to pit, resulting in an impressive, but ultimately disappointing, 2nd place overall.
It only raced once more, at Fuji, where it finished second again, this time to a Nissan GT1 car.
In the 2000s, Toyota pursued a mostly fruitless F1 programme, but the Lexus (Toyota's upmarket brand) LFA supercar was built and raced (prior to release as a road car for a dizzying £350,000!) at the Nurburgring.
Toyota returned to the LMP series for a number of years and finally, in the absence of any serious competition, managed to clinch their first Le Mans victory.
LMP1 Toyota finally brought them Le Mans glory
They were enthusiastic supporters of the new Hypercar regulations and the first to unveil a car.
Initially up against only the privateer Glickenhaus team and a modified Alpine, they dominated for a while, although not totally, as Alpine's old car took some wins in 2022.
GR010 won at Monza in 2024
In 2023, with more competition from the genuine Hypercars from Ferrari, Porsche, Peugeot, Chevrolet and others, they were still the class of the field and continued to be a competitive, often race winning, force in 2024, although the BOP rules certainly made it a far leveller playing field, especially for Ferrari and Porsche.

Ferrari took both Le Mans victories in those years, but Toyota were WEC champions in 2023.
Honda - Half hearted Sportscar racers?
Unlike the other manufacturers, Honda have concentrated on F1 for their motor racing campaigns. However, they have run NSXs at Le Mans on a number of occasions, but despite good reliability, they've been too slow to make any real impact on the race.
However, their Accura US focussed sub-brand became involved with racing in the IMSA class, proving very competitive in the 2010s.

They embraced the Hypercar rules (GTP in IMSA) and continue to race their cars there, but not outside the USA, as of 2024.
