Asahi is one of the largest breweries in Japan, producing pretty generic lagers (think Bud or Miller). However, right across from the front door to the worldwide headquarters in Tokyo is the Asahi Annex Brewery where they brew some truly fine craft beers. Even their twists on the "standard" Asahi beers were surprisingly good. Asahi bought the Sumida River Brewery (the Sumida river is what the bridge goes over in the CorporateHQ picture) and now brews those craft beers right at the headquarters. The weizen is very true to style and the porter, much lighter than a US or English porter, is well balanced and enjoyable.
