Question regarding Japan GP (Motegi)

[harada]

Was thinking about going to Japan at the end of April, to watch the Grand Prix race

I am not planning to go to the race track for all 3 days, I just wanna be there on Sunday to watch the 125, moto2 and motogp race.

just visit Home | The Official MotoGP Website about ticket.

My question is, they are all 3-day pass from their website. Am I able to buy ticket on April 25, outside the track?? Or it's gonna cost more to just buy a one day pass in the gate than the 3-day pass ordered from the web site??

Any place that I can get cheap ticket??

Thanx,
Kevin
