■Top 2 rankers battling with mere gap. Can't take eyes off from No. 3 and 36 cars.

　Cars behind the top 2 cars are packed tightly together with the 3rd ranked No.23 car standing at 11 points behind and all others down to 11th position staying with 3 points or less to each other. In another word, if they cannot score big points, win, or podium-finish at upcoming Round 7 and allow the point difference against the top car to increase to 21 points or more, then they will be out from the title contention.
　For No.23 car which is the leader of the Nissan Z GT500 squad, it would not want to let No.3 car, a sister car that is exactly the same in terms of maintenance, car model, and tire manufacturer, take away the crown so easily. There has been a time, GT-R era, when the Nissan cars dominated the podium. No.23 car must be keen to score their second win at their favorite Autopolis.
　The NSX-GT fleet would not want to forfeit the title contention here especially when this is the last year of Honda NSX-GT. ARTA, fielding 4th-ranked No.16 ARTA MUGEN NSX-GT (Nirei Fukuzumi / Hiroki Otsu) and 7th-ranked No.8 ARTA MUGEN NSX-GT (Tomoki Nojiri / Toshiki Oyu), is the leading force of the NSX-GT squad with a victory at the Round 5 and 6. When it comes to Autopolis, No.17 Astemo NSX-GT (Koudai Tsukakoshi / Nobuharu Matsushita), which was imposed disqualification despite crossing the finish line first at the previous race, is definitely a candidate for the win. NSX-GT itself has been strong at Autopolis if you look at the recent results, thus, there is a high possibility for other teams of the squad to finish in an upper position. Attention should be given to Iori Kimura who will be teaming up with Tadasuke Makino in No.100 STANLEY NSX-GT to substitute for Naoki Yamamoto, who will unfortunately be absent as a precaution due to an injury he suffered from the previous race. Although registered as the 3rd driver of No.8 car for the Round 4, Kimura did not drive practically, therefore, this will be his GT500 debut in a real sense.
　There have been times when the TOYOTA GR Supra GT500 and Toyota cars dominated the podium also, so the group does not disfavor Autopolis. Moreover, their tweak on the aerodynamics has been very effective this season, bringing sound results to the fleet at circuits that require focus on downforce like Suzuka. With Autopolis having similar characteristics, the fleet can be expected to showcase runs with a difference taste. Not only No.36 car at second in the point standing but also 5th- and 6th - ranked No.14 ENEOS X PRIME GR Supra (Kazuya Oshima / Kenta Yamashita) and No.39 DENSO KOBELCO SARD GR Supra (Yuhi Sekiguchi / Yuichi Nakayama), respectively, must be coming in with a strong determination for nothing but win. We would also want to watch closely on whether Tachikawa, who has announced retirement from SUPER GT after this season, and No.38 ZENT CERUMO GR Supra (Yuji Tachikawa / Hiroaki Ishiura) can achieve 6th pole position at here and also the first win at Autopolis, which has been their long-time homework.

　In the driver ranking of GT300 class, No.52 Saitama Toyopet GB GR Supra GT (Hiroki Yoshida / Kohta Kawaai) emerged to the top by winning the previous race with a lead of 10 points from the 2nd - and 3rd -place cars (tie) in the standing. No.52 car now has a chance to clinch the title if it can complete back-to-back win at the Round 7 Autopolis and have No.18 UPGARAGE NSX GT3 (Takashi Kobayashi / Syun Koide) and No.7 Studie BMW M4 (Seiji Ara / Bruno Spengler) at 2nd and 3rd in the standing, respectively, as well as 4th-ranked No.56 REALIZE NISSAN MECHANIC CHALLENGE GT-R (Joao Paulo de Oliveira / Teppei Natori) sink to the lower pack. The possibility may be quite low, but, considering No.52 car is the winner of last year's Autopolis race, it is certainly a victorious candidate regardless of the title.
　No.18 car would want to narrow the gap against, or overtake if possible, No.52 car at the lead before moving on to the final race of the season. The car made an impressive overtaking just before the goal and grabbed the win at the previous race..., but the delight was totally capsized by a disqualification given from a judgment that the car did not barely meet the minimum clearance in the post-race inspection, which dropped them back to the 2nd place in the point standing too. The team would want to undisputedly score their third win of the season at upcoming Round 7 held on Autopolis, where its layout is sought to be favorable to NSX GT3, to capture their long-awaited title at the final round as well as to make up for the disgrace./p>

　Top-ranked No.52 car is chased by two other cars, No.7 car holding the same point as No.18 car at 40 points and the defending champion No.56 car having 39 points. BMW M4 GT3 wearing No.7, though, could not finish in points at its first take on Autopolis last year. No.56 car, too, could only manage a lower position in recent 2 years, so, for these two cars, match-up with the track is something that needs to be worked on in order to stay in the title contention at the final round.
　No.61 SUBARU BRZ R&D SPORT (Takuto Iguchi / Hideki Yamauchi) and No.65 LEON PYRAMID AMG (Naoya Gamou / Takuro Shinohara) must be coming in with "win or nothing" determination. Both cars have been fast at Autopolis, and no win could mean dropping out from the title contention to them. Iguchi, especially, who is from Fukuoka Prefecture, always has a group of supporters visiting Autopolis every year. He would want to embrace the power from his supporters to nail his first win of the season. New cars of this season, No.31 apr LC500h GT (Koki Saga / Kazuto Kotaka / Yuki Nemoto) and No.88 JLOC Lamborghini GT3 (Takashi Kogure / Yuya Motojima), which switched to Huracan GT3 EVO2 from the Round 4, will be, of course, running on the Autopolis circuit for the first time. It would also be interesting to see how these two cars can perform on the track.
