Mizakiya Amazake

This is one of the best amazake (sweet sake) brands that I have tried recently, but I cannot find a website for the company 三崎屋醸造. This product sells at a pretty nice premium, about 370 per bag (which makes 1, 2 or 3 servings). I bet they could enhance sales with the media consultant.
