Katsuyuki Nakasuga, Alex Lowes and Michael van der Mark were all set to defend their provisional pole position, achieved in yesterday's qualifying sessions, in today's Top 10 Trial, which was scheduled to get underway at 15.30.
However, the untimely arrival of Tropical Storm Nari, which made landfall early this morning in Mie Prefecture where the Suzuka circuit is located, meant that the Yamaha Factory Racing Team riders arrived to find the track blanketed by low lying cloud and with heavy rain making track conditions treacherous.
As the rain continued unabated throughout the day the decision was made to cancel both the planned free practice session and the Top 10 Trial on safety grounds, with the result that the grid for tomorrow's Suzuka 8 Hours will form up in the order in which the teams qualified yesterday.
This means that the Yamaha Factory Racing Team trio of Nakasuga, Lowes and van der Mark will chase Yamaha's fifth consecutive Suzuka 8 Hours win from pole position, while the YART Yamaha EWC Team riders, Niccolò Canepa, Marvin Fritz and Broc Parkes, will start from sixth position tomorrow.
The 42nd edition of the Suzuka 8 Hours will get underway with the traditional Le Mans style start at 11.30 local time tomorrow.
