つよぽん
I happened to drop by a store of "Fressey", a community-based supermarket mainly in Gunma Prefecture, and found a label of "Ogo" on Katsuragawa River.
Ogo is the name of a place in Maebashi City, the former Ogo Town, which became Maebashi City after the Heisei no Dai-merger.
I thought it was more acidic than the regular Junmai Ginjo Kayukawa, and the label said so.
If I had to choose a favorite, I would prefer the regular version, but it is quite interesting that there is a limited edition version with a unique label, just like a local sake brewer.
As a side note, the Yanagisawa Brewery is located in the former village of Kasukawa, Setagun, which also became Maebashi City with the Heisei no Daikan merger.
