I bought it at a liquor store in Sannomiya, where I stopped by for sightseeing in Hyogo. According to what I heard, it is a very rare sake sold only at the brewery and its liquor store.
The sake has a complex flavor profile, with a moderate amount of gas, sweetness, and bitterness. It is a little too subtle for everyday drinking, but it is an enjoyable and unusual sake.
