IA1 Moto 1
Kawasaki's Hiroaki Arai went through the first corner hot on the trail of holeshot winner Akira Narita (HONDA), and when the pair completed the opening lap their positions were unchanged. For the first half of the race, Arai paced Narita, waiting for an opportunity to pass. But when they started encountering lapped traffic prudence demanded they slow their pace slightly. Arai had just made it safely around one of the back-markers when another rider went down right in front of him. He moved to avoid the accident, but the other bike blocked his way after bouncing back off the track wall. With nowhere to go, Arai hit the bike he went down, too. He managed to rejoin the race and gave a valiant attempt to regain his lost positions, but with the damage he had taken in the crash it was all he could do to finish 8th. Arai has had very consistent results all season. But for this unfortunate accident, he may have finished on the top step of the podium.

Slightly slow off the line, Arai was 7th at the end of the first lap. He started his pursuit right away, but still from hurting from his Moto 1 crash he struggled to increase his pace. Nevertheless, he continued to push hard and was able to emerge from the fierce battle a few positions higher. In the second half of the race he renewed his efforts to increase his pace and moved up to 4th position. By this time, the top three riders were too far ahead to catch, so Arai maintained a consistent pace to finish the race 4th.

While he missed the holeshot, Takuya Mihara rounded the first corner with the top group. However, after losing his balance in the second corner, in the melee he accidentally touched his foot down, aggravating the knee injury he had sustained at the last round in Hokkaido. Unable to increase his pace enough to get clear of the others, Mihara spent a tough race jostling with the other riders in the mid-pack group. He took the chequers in 8th.

Another tough moto for Mihara. He got a decent start, but was unable to get a clear run to increase his pace, and finished the opening lap in 6th position. In the first half of the race he made cautious moves, gaining three positions to move into 3rd place. In the second half of the race he lapped consistently, and held off the advances of Junya Takenaka (Kawasaki) in the final laps to secure a 3rd place finish. Mihara's perseverance through the tough moto earned him his 9th podium finish of the season.

Hiroaki Arai (8th/4th) :

"When the back-marker went down right in front of me, I managed to avoid him, but his bike came flying back in front of me and I rode right over it. For the second moto, I was able to put the incident out of my mind and I was focused, but I got a poor start and after that I just wasn't riding all that well, so I'm not very happy with that race. After the summer break, I need to win the three remaining rounds. I'll aim to push hard to get a good momentum and win back-to-back races."

Takuya Mihara (8th/3rd) :

"To be honest, I'm not fully recovered from the crashes last round, so I was prepared to have a tough couple of motos. My pace in practice and qualifying was pretty good, but in a race situation I just couldn't ride to my full potential. In Moto 1, in the free-for-all right after the start, I accidentally planted my injured leg, and after that I wasn't able to up my pace. In the second moto, I was able to get a good start and carried that as far as I could in the race, but my rivals were faster. That's racing, I guess. Luckily we have a two-month interval before the next round. First and foremost, I need to heal up, and then give it my all in the last three rounds."
