Katsumasa Chiyo and Mitsunori Takaboshi looked on course for a commanding victory from pole in the #3 NDDP Nissan Z for much of the race, but the arrival of rain in the closing stages opened the door for a late twist in the title battle.
Miyata was running in second, around 10 seconds behind Takaboshi, with a similar margin over the third-placed NISMO Nissan of Tsugio Matsuda, when the conditions started to deteriorate.
