From second on the grid, Miyata passed polesitter and early leader Toshiki Oyu on lap 13 of 51 and then enjoyed a relatively straightforward run to the finish, claiming a dominant 22-second win.
With Mugen’s Lawson finishing only fifth due with a strategy that backfired, Miyata overturned what had been a two-point deficit in the standings to take a 12-point lead into the final four races of the season.
