● Nikka Whisky Yoichi Distillery


In 1918, Masataka Taketsuru, known as the “father of Japanese whisky,” traveled alone to Scotland, where he learned the secrets of whisky making. Upon his return, he began looking for the ideal location to make whisky in Japan, convinced that whisky was best produced in a northern climate. He eventually built his distillery in Yoichi in 1934.
Even today, the Yoichi Distillery makes whisky with the traditional “direct coal-fired distillation” process, placing the highest priority on quality. Its whisky is recognized as being of “the highest quality in the world.” In fact, in 2002, the Yoichi Distillery had the distinction of being the first distillery outside the United Kingdom to be recognized by the Scotch Malt Whisky Society (SMWS), the world’s largest organization of whisky lovers.
The distillery has facilities for tasting and shopping. It also offers a tour of the historical buildings and distillery on its vast grounds that is popular even among those who do not drink whisky. These features make it one of Hokkaido’s most popular tourist attractions.
