The Story of Japanese Whisky

Japan Distills a World-Class Whisky Tradition

Culture Lifestyle

Whisky may have its roots in Scotland, but for nearly a century Japan has been distilling its own brands of the popular spirit. In recent years Japanese whisky has earned a name for itself, winning fans and widespread acclaim overseas. We visited two distilleries in Japan to find out more about this burgeoning tradition.

Highball Boom Lifts Whisky Market

But in 2009 the Japanese whisky market finally started to flow again, and sales increased in each of the five subsequent years to 2014. This turnaround owed much to Suntory’s highball campaign that brought whisky to the attention of a younger generation of drinkers.

Amid the highball boom, Suntory’s Single Malt Hakushū has also enjoyed popularity, promising consumers the “invigorating aroma of a forest,” as the head of the distillery, Ono Takeshi, explains: “Our no-age-statement whisky evokes the smell of young leaves, while our 12-year-old is reminiscent of fresh greenery. Our 18-year-old single malt, meanwhile, has a fruity flavor, and the Hakushū single malt that we age for 25 years is like a rich jam.”

Suntory Takes a Fresh Look at its Whisky Production

Ono joined Suntory in 1989. He became involved in whisky production as a technician and blender at the time when Japanese whisky’s popularity was in decline. Around 1990, Suntory launched a company-wide project to rethink its whisky production from square one by bringing a scientific approach to bear on the experience- and intuition-based methods that its technicians had relied on up to then.

Simply put, the process of making a malt whisky involves, first of all, germinating two-rowed barley to create malt, which is then smoked over a peat fire. In the second stage, this malt is mashed by crushing it and adding hot water, and then slowly heated to convert the starch into sugars. The “wort” that results is extracted and placed in a fermenting vat, and yeast is added to it. And after about 70 hours, this fermented liquid, or “wash,” has an alcohol content of 6 to 7%.

The liquid is passed through a pot still two separate times to create a colorless alcohol called “new pot” that has an alcohol percentage of around 70%. This is the fourth stage of the process. Water is added to the new pot to get the percentage down to around 60%, and this is then aged in casks for at least 3 years—although more often for 5, 10, or 15 years.

Ono explains more about the nature of the project: “If you take the fermentation process, for example, it includes the phases of growth, ripening, and then a withering away. We tried to look, scientifically, at the best point at which to extract the components. Based on this sort of approach we also learned that if the froth produced at the beginning of the fermentation process is kept at a certain height it will make it possible to extract the ‘umami’ elements. In doing this, we were able to evaluate the umami elements by measuring the level of change in a particular amino acid within the wort. These are some examples of the sort of scientific measures we’ve been implementing.”

“That was a period that followed the great boom period for whisky,” Ono recalls. “We realized that the old approach would no longer work, and that we would need to come up with something better. Suntory began sales of its Single Malt Yamazaki in 1984, but we knew that in the future we would have to come up with more distinctive malt whiskies, and that this would also require a change in our marketing approach.” 

Ono also points out that, when it comes to making whisky, you can’t just simply follow the recipe. “Differences in temperature or humidity at the time of preparing the barley and fermentation require different approaches. It takes a long time for a distillery to develop the know-how and capacity for fine-tuning needed to respond to these differences. Our distillery here has been open for 33 years, but it took us quite a while to get to the level we are at now.”

Nikka Produces a World-class Single Malt

Nikka, Suntory’s rival, also launched a concerted effort in the 1980s to raise the quality of its lineup, aiming to create world-class whiskies. This effort was spurred by the company’s concerns about the increasingly fierce competition from foreign distilleries as Japanese tariffs on foreign alcohol continued to fall.

Sakuma Tadashi, the chief blender at Nikka’s Yoichi distillery, joined the company in 1982. “At the time,” he recalls, “the company gathered together all of its technicians to experiment with various things. We started by taking a fresh look at our ingredients, the types of yeast used for fermentation, and our casks, and this led us to make quite a lot of changes in our production approach—from the malting stage up to distillation.”

The company’s efforts bore fruit 20 years later when its Single Malt Yoichi 1987 won the World Whiskies Awards’ “Best Single Malt” prize for 2008, marking the first time for a Japanese single malt to capture the world’s top prize.

“Winning that award was the culmination of everything we had been aiming for, and there was nothing haphazard about that achievement,” Sakuma says with pride. “In the years since we have won many more awards, and this success was built on the technical efforts we began making back in the 1980s.”

In 1968, the founder of Nikka, Taketsuru Masataka, looked back on his professional life in a set of serialized articles for Nikkei Shimbun. In describing his hands-on apprenticeship at distilleries in Scotland he wrote that, “The wonderful aromas and deep-rooted traditions that I encountered back then shine through even today . . . But it proved very difficult to create those aromas ourselves in Japan.”

The industry has come a long way since those days, however, as demonstrated by the high praise Japanese whiskies are now earning.

Contrasting Outlooks of Nikka and Suntory

In recent years, Suntory has been winning top prizes in global contests for its blended whisky Hibiki and its Yamazaki single malt, just as Nikka has been doing for its blended pure malt Taketsuru. But, interestingly, the two companies hold quite different opinions when it comes to the question of how—if at all—Japanese whisky differs from Scotch whisky.

For Nikka, the ideal is to create whisky that is an extension of the original Scotch tradition. “There is no essential difference between our whisky and Scotch,” chief blender Sakuma asserts. “We don’t want to place too much emphasis on the fact that our whisky is produced in Japan.”

“Basically we are producing whisky that speaks the ‘same language’ as Scotch, although their accents might be a bit different. If you pour out a hundred glasses of Nikka whisky and Scotch whisky, I think you’d find it hard to identify which ones were Japanese and which ones weren’t.”

Suntory, for its part, emphasizes how its whiskies differ in character from Scotch whisky. The company, which has a leading share of the Western spirits market in Japan, has sought to create products that are well suited to Japanese cuisine and culinary tastes.

“Scotch is a drink born of the climate and landscape of Scotland, “says the head of the Hakushū distillery, Ono, “whereas our Japanese whisky is fostered by the four seasons of Japan.”

“Japan has a much more favorable climate than Scotland in terms of aging whisky because of our more temperate climate, and this lends Japanese whisky its distinctive qualities. On top of this, we have cultivated whiskies that suit the well-balanced and smooth flavors favored by the Japanese palate. And now these flavors also seem to be winning over whisky lovers around the world.”
