Hi Johnny 34 and welcome - get stuck in at any time
Yup, Jonny Rea and Carlos are one of the key teams this year...and you can't get more "key" than Team HRC at a track owned by them
Last year they had live coverage (with Japanese commentary), along with lap timings on the official site and I would imagine it will be the same again, though it does tend to get tough to see anything once the sun goes down
I'm going to try to keep my site updated with what's going on from one or two people at the track and maybe some inside info - but the official site is one of the best there could possibly be.
As you well know, this is BIG in Japan
