It marked a monumental win for the Japanese manufacturer on home soil, its first since Bahrain 2014 and the first for ex-Formula One star Kobayshi, who shared driving duties with Mike Conway and Stephane Sarrazin.
Duval and co-drivers Lucas Di Grassi and Oliver Jarvis settled for second after dominating the first half of the race, in a flawless run for the No. 8 car.
The No. 1 Porsche 919 Hybrid of Mark Webber, Timo Bernhard and Brendon Hartley finished less than 18 seconds behind in third, putting all three LMP1 manufacturers on the podium.

Toyota's sister No. 5 entry came home fourth after opting to change tires on its final stop, ahead of the championship-leading No. 2 Porsche trio of Neel Jani, Romain Dumas and Marc Lieb, which completed the top-five.
It was another tough day for Audi, with the No. 7 car retiring with hybrid failure after Benoit Treluyer pitted the diesel-powered contender just 20 minutes complete.
The car returned to action one hour later, with the front driveshafts removed, but was deemed illegal by officials as it was outside of the car's homologation.

Will Stevens took the No. 26 Oreca 05 Nissan across the line 1.398 seconds ahead of the No. 43 RGR Sport Ligier JS P2 Nissan of Bruno Senna in second.

The No. 67 Ford GT of Andy Priaulx and Harry Tincknell started the race second on the grid, the latter taking over the lead of the sister No. 66 entry in the hands of Olivier Pla at Turn 1.
From there on there was no stopping the Fords, edging away from the AF Corse Ferraris that were only able to lead the field as the Ford GTs made their pitstops.
There was a small scare for Tincknell, who made with slight contact with the No. 78 KCMG Porsche 911 RSR right before the halfway mark.
The pole-sitting No. 66 Ford of Stefan Muecke and Olivier Pla quickly settled into second and never really threatened the lead of their teammates.
Pla had a spin at Turn 3 right before his final stop but was able to continue without issues but with a bigger gap to the leaders, adding up to 15 seconds after six hours of racing.
It marks the first win for the Multimatic-run, UK-based CGR team in WEC, dominating the entire weekend by leading every session in the build up to the race.
