I'd have to say that I am huge fan of Baird Brewery Beers out of Numazu. Not off the wall crazy beers, but very good flavor with a solid balance through the front, middle and back....
Shiga Kogen is another favorite of mine out of Nagano...
Have just finished a 2 Brothers Foo Kung rice lager.
Usually not a fan of lagers - often find them too thin & watery.
Liked this beer tho. Crisp & clean. Would like to try with a feed of Japanese or even a spicy curry.
