125cc championship leader Andrea Iannone will start on pole for the Motegi race thanks to the cancellation of today's qualifying session.
The Italian had been quickest in the dry Friday practice that will now decide the order, beating pre-season title favorite Julian Simon by 0.179 seconds.
Simon had topped the wet session this morning, ahead of Marc Marquez, although the latter will start back in 10th based on dry times.
Stefan Bradl and Esteve Rabat complete the front row, ahead of Nicolas Terol and Dominic Aegerter.
