We had this as a welcome drink at Super Hotel in Tsuruoka City.
It has a gorgeous mouthfeel and a good flavor.
The taste is addictive and I want to enjoy it again.
Purchased at Hasegawa Sake Shop in Tokyo Station basement.
It was often featured on youtube, but I had never seen it in my hometown, so I bought it immediately.
It has a gaseous feel similar to soda water, but the flavor is strong with a clear, crisp taste. I also felt a bit of bitterness in the back.
