wheat bear - maybe it is japan...

"Wheat beer is a top-fermented beer which is brewed with a large proportion of wheat relative to the amount of malted barley. The two main varieties are German Weizenbier and Belgian witbier; other types include Lambic (made with wild yeast), Berliner Weisse (a cloudy, sour beer), and Gose (a sour, salty beer)."
