Mars Shuzo is the quiet giant of Japanese whisky. The best kept secret in the whisky world are the two exceptional distilleries, Komagatake and Tsunuki. While both have been available on occasion in single malt form, they are almost never seen in the US as single casks, and typically a single barrel of either commands a significant premium. The company can trace its roots to the origins of Japanese whisky through their founder, Kiichiro Iwai. Just like Suntory, Hombo Shuzo was there from the start. It was in fact Iwai who enlisted Masataka Taketsuru to travel to Scotland in order to learn the age old techniques for making the world’s most complex whisky. Upon his return, Hombo was not able to construct the distillery, so Taketsuru-san took the plans to Suntory. But in 1949, Kiichiro Iwai would complete his dream of building pot stills and distilling Hombo’s own malt whisky. And while Iwai-san represents one of the three pillars of Japanese whisky, their modern commitment to the category rests squarely on the shoulders of one great man, Kazuto Hombo. Hombo-san is a true lover of the finer things, and his love of whisky kept the wonderful old stills running. His belief that Japanese whisky would one day be a worldwide success is singularly connected to the construction of the Nagano plant where the original stills were moved, and while Hombo-san was ahead of his time, the plant would see very little production over the next 30 years. He was ready when the whisky boom began and production restarted in 2014. Now Komagatake is making some of the world’s best whisky. Stylistically, the distillery offers an elegant and refined malt, but this single cask is truly superb. Peated to 20 ppm, you might expect something very smoky and forward, but instead you have an elegant, ultra complex expression of malt that is on par with the very finest available anywhere. Let’s dive in! One of the old single casks out there. The color is a shimmering yellow gold (0.5). The nose is an explosive mixture of maritime flavors and sweet orchard fruit: oyster shell, yuzu peel, galangal, creosote, white ash, pear preserves, licorice root, salted grilled lemons, and lanolin. The palate is razor sharp and chiseled, with a big citrus note and a strong saline character up front, followed by similar white ashy smoke, which does not dominate whatsoever the fresh, juicy fruit: greengage, apricot, green grapes. It absolutely adores water, softening the smoke and reminding me of a well matured, less tarry style Caol Ila. An absolute winner by any measure that feels like a rapturous eye opener to the potential of this wonderful little mountain distillery.

What a fantastic first private barrel of Mars Komagatake we have here, and this feels like just the beginning of many great things to come. The spirit and maturation at the Komagatake distillery, perched high in the Japanese Alps of Nagano at roughly 2,600 feet above sea level, take on fresh mountain character in a truly striking way. The nose is bright and expressive, with wisps of smoke from the lightly peated malt at 20 ppm, alongside grilled pineapple, salted licorice, lemon custard, and roasted honey. On the palate, those flavors broaden into apricot Danish, ocean brine, star anise, and a hint of campfire, before settling back into bold citrus and warming spice. Water is more than welcome here. It softens the edges, enhances the delicate sweetness of the smoke, draws out more tart pastry notes, and expands the spice profile. We’re lucky to have this one, and you will be too.

Notes

This singular cask from Mars Komagatake offers a direct link to the origins of Japanese whisky and one of the category’s most important pioneering producers. Crafted by Hombo Shuzo, a family owned company founded in 1872, Mars traces its whisky lineage to the earliest era of malt distillation in Japan, long before Japanese whisky achieved global acclaim. Hombo was among the first producers to seriously pursue domestic malt whisky, helping establish the foundation of what would become a national tradition. The Komagatake distillery was founded in 1985 high in the Japanese Alps of Nagano, chosen for its pristine mountain water, cool climate, and dramatic seasonal temperature swings. These conditions proved ideal for maturation, allowing whiskies to develop remarkable depth and structure even at younger ages. Like much of the industry, Komagatake experienced periods of dormancy during market downturns, but its revival in 2011 marked a pivotal moment in the modern resurgence of Japanese whisky. Today, Komagatake is widely regarded as the spiritual and technical heart of Mars, producing some of the most authentic and characterful single malts in the country. This single cask, bottled exclusively for K&L at natural cask strength and limited to just 160 bottles, is not only exceptionally rare but historically significant. As the very first Komagatake barrel selection in K&L’s history, it stands among the finest examples of Japanese whisky available anywhere in the world.
