The seven days since Aragon saw the MotoGP top three of Valentino Rossi, Jorge Lorenzo and Marc Marquez all suffer accidents in testing or training.
World championship leader Rossi looks to have got off most lightly, being left with an abrasion to his arm after a fall during the post-race Michelin test.
“During the test, I crashed but there were no further consequences, only a little abrasion on my arm. I'm fine and I'm ready for the tripleheader!” Rossi said ahead of this weekend's Japanese round.
Rossi's title advantage has been cut to just 14 points, with 100 still available, after Yamaha team-mate Lorenzo's latest victory at Aragon.
But the Spaniard then hurt his shoulder in a training accident last Saturday. Described as a ligament sprain, Lorenzo insists he will 'race without problems' in Motegi, although it is sure to give Rossi a small psychological boost after struggling to match Lorenzo's dry pace since the summer break.
Lorenzo has also claimed victory at Motegi for the past two seasons, while Rossi has been winless in Japan since 2008. However a memorable showdown between the pair (over third place) went in Rossi's favour in 2010.
“We're on our way to Motegi to begin a very important part of the season. Motegi is a track that I like very much. Here I made a good race in the past and also last year I had a good weekend, but Jorge was stronger than me so he won,” said Rossi, in pursuit of a tenth world title at the age of 36.
“For this reason I will have to give my all because there are only 14 points between him and I. These points may seem a lot but they are few.
“We must give the maximum because we are competitive, which we have demonstrated up to this point. There will be three races in a row and it will be important not to make any mistakes, but at the same time make sure to get the best possible results. I feel good.”
Marquez, who has slipped 79 points from Rossi after a fifth DNF of the year at Aragon, required surgery after fracturing his hand in a mountain bike accident.
While effectively out of the title fight, his injury could still influence the championship outcome having been the rider most likely to take points from Rossi and Lorenzo.
Motegi is the first of three successive flyaway races, followed by the season finale in Valencia.
