Italian megastar Valentino Rossi is likely to sit of the Japanese MotoGP round.

Nine-time world champion Valentino Rossi is in doubt for October’s Japanese MotoGP, expressing his fears over the current safety concerns in the land of the rising sun.

Rossi is the latest top level MotoGP rider to voice his concerns over the event, joining Australia’s world championship leader Casey Stoner and current world champion Jorge Lorenzo in doubt for the event.

“I really don’t think I’ll go to Japan,” Rossi reportedly told the BBC. “I was hoping the championship organisers would make the right decision, but that hasn’t been the case and now we’ve got a serious problem.”

It’s believed Rossi isn’t only concerned about the radiation, but also for the possibility of more disasters that could potentially arise.

Both Stoner and Lorenzo have admitted they are still undecided if they will attend the event, despite both stating at the German GP last month that they weren’t planning on attending.

Unlike Stoner and Lorenzo, Ducati rider Rossi doesn’t have the pressure of a Japanese manufacturer behind him to attend the event.

The Japanese GP was originally scheduled for April, however the earthquake, tsunami and nuclear emergency that struck the country in March forced organisers to reschedule for 2 October.

Motegi is north of Tokyo, hundreds of kilometres south of the most highly affected radiation zones in Japan.
