In Japanese, "Budwiser" is most well-know beer. However, I think Samuel Adams is best beer. I have never seen Samuel Adams or similar taste of it in Japan. If Samuel Adamus will be import to Japan, it is certain to sell a lot of them.

The Boston Beer Company (NYSE: SAM) is an American brewing company founded in 1985 by Jim Koch in Boston, Massachusetts, USA. The beers were originally contract brewed by the Pittsburgh Brewing Company, though today, more than 60% of its beer is produced at the company's Cincinnati brewery. Miller is also a contract brewer for a portion of their production.[citation needed] The brand name for the beers is Samuel Adams (often abbreviated to Sam Adams, even in advertisements), after Samuel Adams, a brewer[1] and an American patriot famous for his role in the American Revolution
