OKUNOMATSU. Currently in their 19th generation of brewing, this is a well-established old company that incorporates healthy dollops of modern ingenuity. Their contest sake wins top awards with great regularity, and their regular stuff is popular as well. They try new things as well with great success, including a sparkling sake and something they call Zenmai Ginjo, in which the alcohol added to their (non junmai) ginjo is made by distilling their own junmai-shu. An industry first, and an enjoyable sake to boot. They have a range of products imported into the US, including their tokubetsu junmai-shu, the above-mentioned sparkling sake (Okunomatsu FN Junmai Daiginjo), and their top grade junmai daiginjo.
From last year from John Gauntner's sake-world.com:
"Okunomatsu "FN" Junmai Daiginjo. Developed by Okunomatsu (of Fukushima Prefecture) for the express purpose of allowing the winner of the Formula Nippon race, Japan's premier F1 auto race, to spray sake and not champagne in the winner's celebration. I'm serious. Higher alcohol content of about 14 percent, good powerful fizz too."
Sounds interesting...but sounds like it's not what you have. The only other info I could find was that he lists it as a "fairly large brewer" from Fukushima, "balanced and unique".
