A total of 13 cars, representing the entire GT500 field except the two NISMO-run Nissan Zs, were in action for the opening day of what marks the final group running before next week's official Okayama test.
Continuing the pattern seen in previous tests, it was the Honda NSX-GT contingent that dominated the timesheets, with all four of the marque's Bridgestone runners sitting at the top of the charts.
