In front of a huge crowd of 49,500, a total of 40 cars, including two that joined from the pitlane (the No.88 Lamborghini and No.70 Porsche), started the 63-lap race, reduced from 65 laps due to two extra formation laps spent behind the pace car.

Seiji Ara in the No.38 Supra made a smooth start from pole position but was overtaken by Satoshi Motoyama in the No.1 Fairlady Z into the first corner. Both cars then dropped down the order after this corner, Motoyama crossing the start/finish line in fifth while Ara dropped back to the tail end of the class.

Toshihiro Kaneishi in the No.3 Fairlady Z was punted into the first corner gravel trap, instantly getting stuck. The 2001 German F3 Champion was able to rejoin though had lost two precious laps and suffered a damaged oil line. Kaneishi returned to his pit after running 15 laps and took off his helmet. His teammate Erik Comas ended the day without driving in the race.

After the confusion at the first corner on the opening lap, Akira Iida in the No.6 Supra came out on top followed by Manabu Orido in the No.25 Supra, Hiroki Kato in the No.100 Honda NSX, and Andre Couto in the No.39 Supra. On the following lap, Orido overtook Iida to take the lead. The winner here last year ran well with the same package as in 2003; a Supra on Yokohama ADVAN tires. He began to increase the gap over second-placed Iida little by little in the ensuing laps.

On lap 3, Couto in the No.39 Supra had a half spin and dropped from fourth to eighth. The Macao-based driver then battled back courageously to recover the position.

Meanwhile, Motoyama began to fight through the field, steadily catching up with the leaders. He overtook Kato in the No.100 Honda in the early stages to take third place. Ahead of them, Iida began to reduce the gap to the top runner Orido and soon caught up with him. Iida finally overtook the No.25 ADVAN Supra on lap 20. However, he was the first of the top runners to pit, making the stop early due to badly wearing tires. Iida handed the wheel of the No.6 Supra over to Wakisaka after only 25 laps.

Huge battles for first place raged between Orido, Motoyama and Couto in the thick of the fight. Motoyama pitted on lap 29, handing the wheel of the No.1 Nissan to Richard Lyons. The NISMO crew demonstrated superb pit work to get the car out ahead of the No.6 machine driven by Wakisaka. On the following lap, Couto also pitted. Thanks to the team mechanics' excellent performance in the stop, driver partner Jeremie Dufour joined the track just ahead of top runners. As he was on cold tires, he had to let the pair by, not being able to safely defend the position. "I didn't want to do anything stupid"' he said later. Orido pitted on the following lap, passing over to Dominik Schwager who himself got out on track just in front of the No.39 car. Consequently, Dufour dropped back to fourth place.

All around the track, the spectators were treated to some serious excitement as the leaders diced for position; Wakisaka, Schwager and Lyons were locked in a fantastic side-by-side battle while Dufour watched thirstily for a chance to attack.

On lap 43, Lyons finally overtook Schwager to come out on top. The Irish Nissan driver began to pull away and Schwager got caught by Wakisaka who really started to pile on the pressure. Dufour was close behind, keeping Wakisaka in sight. At the back of this group, Benoit Treluyer in the No.12 Nissan caught up with Takeshi Tsuchiya in the No.36 Supra who was lying in fifth. In the closing stages of the race, they joined the tail of the three-man battle for second. Among them, Wakisaka spun on lap 54 dropping back to sixth. The order was now Lyons, Dufour, Schwager, Treluyer, Tsuchiya and Wakisaka.

In the final laps, Treluyer, Wakisaka and James Courtney in the No.37 Supra who had passed his teammate Tsuchiya, fought a fierce tail-to-nose battle. On the final lap, Wakisaka overtook Treluyer for fourth. In the Honda camp, the No.100 NSX with Kato and Shinji Nakano finished tenth after spinning only a few laps from the end. However, they were by far the fastest Honda runners.

GT500 Winner - No.1 Xanavi NISMO Z

Satoshi Motoyama : "Although I overran at the first corner just after the start because the tires were still cold, the car was good and I drove with confidence. I was hoping I could have taken the lead before passing the wheel to Richard, but I had a good race anyway. I wanted to win today, though I thought finishing in second or third would also have been good enough."

Richard Lyons : "It was hard for me to join the race in such a huge battle, particularly on cold tires. As I had a relatively long stint, I had to save the tires. I overtook the No.6 car when it struggled in traffic and for the No.25 car, I waited for their tires to lose grip - I felt my tires were in better condition than theirs. This is a track where tire choice is a decisive factor. Satoshi also had a good tire choice. That is the important point of our victory today."

Shinichi Yamaji in the No.7 Mazda make a good start from Pole position to take the lead into the first corner. Nobuteru Taniguchi in the No.19 Celica also got off the line well, jumping up to second place from the third row on the grid, and Morio Nitta in the No.43 Garaiya slotted into third place. These three cars formed the top group in the early stages of the race.
Tetsuya Yamano in the No.16 Honda, the current Championship standings leader, seemed to have a difficult race, dropping down to eighth place.

Yamaji in the No.7 Mazda was in good form today, pulling away as the race progressed with the unique Rotary engine sound.

Nitta demonstrated good form too. On lap 28, the winner of Rounds 4 and 5 overtook Taniguchi to take the Garaiya to second place. He completed 31 laps before handing the wheel to Takagi.

Top runner Yamaji pitted as scheduled on lap 33. By that time, he had built a huge gap of over 10 seconds when he passed the wheel to Hiroyuki Iiri.

The No.43 Garaiya, now driven by Shinichi Takagi began to close the gap to the No.7 Amemiya RX-7 when these cars were carrying a full load of fuel. Iiri seemed to have a hard race in the second half, but he then increased the gap again as the car became lighter.

Behind them, Katsuo Kobayashi in the No.77 Subaru became the focus of the spectators' attention. He charged up the timing monitor, driving skillfully and lapping consistently quicker as he worked his way up to third place. He even caught up with Takagi in the Garaiya in the closing stages.

In the end, Iiri crossed the line first followed by Takagi in the Garaiya and Kobayashi in the No.77 Subaru. Yagi in the No.16 Honda NSX came home in sixth place. With this result, the driver pair of Morio Nitta and Shinichi Takagi take over the lead in the Championship standings.

GT300 Winner - No.7 Amemiya Aspara Drink RX7

Shinichi Yamaji: "After our Malaysian victory, we have had hard races due to the heavy success ballast on the car. I regret we've been unable to give good race results for the Rotary engine funs. I did my absolute best today, driving carefully but pushing hard in the second half of my stint, using the tires to the limit."

Hiroyuki Iiri: "I saw the Garaiya in my mirrors when I went out on track. This didn't bother me and I just concentrated on driving as Yamaji and the team had suggested. I'm very happy to take this second victory of the season."
