Katsumasa Chiyo and Mitsunori Takaboshi took full advantage of the mixed conditions in Sunday's 100-lap race in their Michelin-shod #3 Nissan Z, taking their first victory of the season by a commanding 43.9 seconds.
Two Honda NSX-GTs completed the podium, as ARTA duo Hiroki Otsu and Nirei Fukuzumi were best of the Bridgestone runners in second, followed by Team Kunimitsu pair Naoki Yamamoto and Tadasuke Makino in third.
The race was red-flagged after 68 of 100 laps when the Tsuchiya Engineering Toyota GR Supra GT300 car of Seita Nonaka stopped at the side of the track at Turn 3 and started going up in flames.
Such was the severity of the blaze that an initial safety car period gave way to red flags when it became clear that the marshals wouldn't be able to contain the fire immediately. Nonaka escaped uninjured.
The race resumed after an interlude of 50 minutes, in which time a rain shower doused the track, delaying the restart, but the full 100-lap distance was completed before the time limit was reached.
Victory in a topsy-turvy GT300 contest went the way of the #11 Gainer Nissan GT-R NISMO GT3 driven by Keishi Ishikawa and Ryuichiro Tomita.
