Travelling to Japan - Questions about Super GT
 

I will be travelling to Japan in April and I'm hoping to attend the season opener for the 2018 Super GT series at Okayama International Circuit on April 8th. I am a huge fan of the series, watching the live streams on Youtube for several years (they don't televise it in Canada).

Unfortunately, most sites about the series aren't English-friendly. If a member in Japan or someone who is familiar with the Super GT series can help me with the following inquiries, that would be much appreciated.

Race Info:

Date: Sunday April 8th, 2018
Location: Okayama International Circuit

Questions:

1) Where is the best place for me to buy tickets when they become available? Sites I can find are completely in Japanese and I would rather have the guarantee of entry vs purchasing at the gate

2) What is the cost of a ticket and what are my options (e.g. grounds access, seated, paddock/pit passes etc.). I am looking to have a seat, and if I can choose what stand/part of the track that would be a bonus!

3) Is there a shuttle from any nearby train stations to the track? I am trying to decide between taking the train there or renting a car and driving myself.

Looking forward to seeing some responses, thanks in advance for your help. Happy New Year :)
