Yamanashi Prefecture Governor Shomei Yokouchi and local vineyard operators visited London to begin marketing their wines in Europe, the Yomiuri Shimbun reported in January.
About 300 guests tasted 15 different Koshu wines matched with Japanese appetizers at the Embassy of Japan on 12 January.
The Yamanashi team gave a hearty presentation because, although the UK is not a major wine producer, the market there is considered by the industry to be very influential and lucrative by world standards.
