New info on more beers:

I've updated the list info from this page. However, nothing seems to be 100% certain, so don't bet the home on it.

UPDATE FROM FRIDAY:

I went on Friday and the beer was not bad at all. 2 big halls, Beer is well labelled (if you look up to the huge banners overhead). Everything is nicely spaced out. Lots of room. Friday wasn't busy at all and no queues for the beer. Not sure about today. If you see DH or Nate from the Good Beer and Country boys, please say hi from Chuwy. Unfortunately, I have to be in Hakone today and tomorrow (its not so bad). Enjoy the festival!
Chuwy's reccomendations:
Aged 9 tailed fox from Nasu Kogen (made in 1999)
Nihonkai pilsner
Minoh DIPA
Brewmaster Kabos and Honey
Shonan oatmeal stout
Yokohama liberty ale
Iwate Kura chocolate stout (sooo much cocoa!)
Stone vertical epic
Bear Republic red rocket (if it's in good condition this is awesome)

Drink Caramel sweets at your peril!
This list is changing constantly. Either new brewers are being added or some are taken off the list. Not very well organised, if you ask me. Still, all I can do is keep checking it and trying my best to update this blog. Chuwy (13/3).
p.s. don't believe the bull that you can't buy tickets on the door. There was a rumour that only 30 tickets were left. Pretty damn sure they haven't sold 800 tickets for Friday. I'm just gonna turn up and buy mine at the door.
