I have only had the pleasure of drinking two japanese brand beer, namely Asahi Super Dry and Kirin. Both were oke, they did the trick. Both got me to the state of mind they were supposed to bring me to.
But I dont think its great beer, I've had allot better.
On a side note; most Dutch people consider Heineken an average beer brand here, but sadly it is the most known beer brand from the Netherlands.
