The Six Hours of Fuji has been red-flagged due to visibility issues, with the race coming a halt in the second hour after a rain-soaked and treacherous start.
Race Director Eduardo Freitas elected to suspend the race with only 1 hour and 18 minutes completed, 30 minutes after the safety car was deployed due to the deteriorating conditions.
The No. 2 Porsche 919 Hybrid of Earl Bamber leads, having not yet made its first pit stop, ahead of the No. 8 Toyota TS050 Hybrid of Kazuki Nakajima in second.
The seventh round of the FIA World Endurance Championship started under safety car conditions due to the rain, with the field having been turned loose on Lap 5, although initially under a Slow Zone.
Pole-sitter Bamber led from the start and bridged out a 12-second lead prior to the second safety car period of the race just prior to the one-hour mark.
Drivers have been allowed to vacate their cars, which are parked on the front stretch in parc ferme conditions.
The clock continues to run, with a firm curfew of 5 p.m. enforced.
Should the race be called early, only half points would be awarded unless more than 75 percent of the race time is completed by the overall leader.
