Ōka Ginjo-shu is a ginjō sake produced by Dewazakura Shuzō. First released in 1980, it was created to make this style of sake accessible to a wider public and went on to help popularize ginjō sake in Japan.

It is made from Japanese rice polished until 50% of each grain remains and has an alcohol content of 15%.

It has the fruity aroma characteristic of ginjō sake and a refreshing taste. It is particularly recommended served chilled at 5–15 °C.
