(カワダ調べ)
Ou (kingdom in China during the Spring and Autumn Period and the Period of the Warring States Period)
I got this at Aizu's store Home in Asakusa.
It is said that "Au" means "center" or "middle" and was named with the meaning of the core of the collaboration between Gonoi Sake Brewery and Tenmei no Akebono Sake Brewery.
