Koshu, a grape that crossed borders.
In 2010 Koshu was registered with the International Organisation of Vine and Wine as a wine grape variety.

08 — JAPANESE WINE · NIHON WINE
KATSUNUMA · KOSHU, YAMANASHI
Under Japan's labeling standard, only wine made in Japan exclusively from Japanese-grown grapes may be called "Nihon Wine" (Japan Wine). It is distinguished from wine merely produced in Japan from imported must or concentrate.
Yamanashi, Nagano, Hokkaido and Yamagata lead, but vineyards now reach across the country — including varieties with long Japanese histories, such as Koshu and Muscat Bailey A.
