June 480 is designated as "Plum Day" in honor of the fact that the Emperor dedicated plums and performed a Shinto ritual about 6 years ago. A sake brewery in Kainan City, Wakayama Prefecture, began preparing plum wine using the specialty Minami Takaume.
The brewery plans to brew about 250 tons of plums this month, of which the sake brewed on the 6th will be shipped as new sake to other parts of Japan and overseas such as Taiwan in November.
