But he told Motorsport.com that losing the SUPER GT crown through no fault of his own has given him a philosophical approach to this weekend's pivotal race.
"It’s hard to comment [on the title situation]," Hirakawa said. "It was the same [in SUPER GT] and I think you just have to accept whatever happens.
"[In the second Suzuka race] I had luck on my side [compared to Yamamoto and Cassidy], but I don’t know what will happen at Fuji. If you get lucky, you get lucky."

Asked if revenge was on his mind this weekend, Hirakawa replied: "If it’s possible, of course it would be great, but I don’t want to be greedy. I just hope I can finish the season with a good result, but anyway I will give it everything and accept whatever happens.
"Of course it was frustrating, what happened in Super GT. I did everything I could. And I’ll likewise do my best in Super Formula at Fuji."
Hirakawa pointed out that he set the fastest time during pre-season testing at Fuji way back in March, before the season was halted amid the global health crisis.
"I think it’s good we can settle it there," he said. "During the March test I had a good feeling and I set the top time. So I feel I can do very well."
Following the events of Suzuka, Hirakawa and Yamamoto now have two non-scores each this year, meaning that the new-for-2020 dropped score rule will not impact their battle.
On the other hand, outside title contenders Cassidy and Tomoki Nojiri, however will both have to discard their worst scores after Fuji, as Cassidy scored three points for pole even though he didn't finish the second Suzuka race.
