Distillery Water Dragon in Mishima (三島), Shizuoka Prefecture, will release two new bottlings of its young, bourbon-style “Little K” whiskey on November 11, 2026. “Little K 2026 2nd” is the oldest Little K yet at 23 months, and “Little K mellowship” is the first in the series to swap rye for wheat in the mash. The announcement, made on October 5 by the distillery’s owner Whiskey&Co. (ウイスキーアンドコー), matters for two reasons: it is close to the last Little K that can honestly be called “under two years,” and it confirms that one of Japan’s few bourbon-focused distilleries is now experimenting with mash bills rather than simply waiting for its casks to age.
This is a separate release from the three single-barrel bottlings Water Dragon distilled for Tokyo brand CRAFT WONDER, which we covered on October 3. Little K is the distillery’s own house label.
Two bottles, two different experiments
“Little K 2026 2nd” is a vatting of nine new-oak casks, all filled 23 months before bottling. It comes in a 375ml bottle at 61% ABV, priced at 4,950 yen including tax, with 4,300 bottles. “Little K mellowship” uses corn, wheat and malt instead of the series’ usual corn, rye and malt. It is bottled at 54% ABV in the same 375ml format and at the same price, but the run is smaller, at 2,200 bottles. The company describes the wheated version as softer and sweeter on the palate with a long finish; we have not tasted either.
The more interesting detail is how openly Whiskey&Co. has documented the series’ age progression. According to the company, the first Little K (June 2025) combined 10- and 13-month-old spirit. The second (November 2025) used 15- and 19-month spirit, and “Little K 2026” (June 2026) blended 17-, 18- and 20-month spirit. The new release is a single age, 23 months. Each of the first three editions sold out, in October 2025, March 2026 and September 2026 respectively. The first won a Master medal at The World Whisky Masters 2025, and the second took a top gold at the Tokyo Whisky & Spirits Competition 2026.
Whiskey&Co. says it chose the name “Little K” deliberately instead of “new born,” the label most Japanese craft distilleries use for their first young releases. Its argument is that a bourbon-style spirit aged in new charred oak develops differently from Scotch-style malt, and that the early stages are worth presenting as a product of their own rather than as a preview.
Why this matters
Most of Japan’s new distilleries follow the Scottish template: malted barley, pot stills and long maturation in used casks. Water Dragon, opened in 2023, went the other way. It makes American-style whiskey, spelled with an “e,” from a grain mash aged in new American oak. The Little K series is effectively a public record of how that spirit behaves in a Japanese climate, one batch at a time. Few distilleries in Japan publish this kind of month-by-month maturation data, and for anyone following craft distilling here it is a rare look at the curve rather than just the end point.
The 23-month mark is also symbolic. In the United States, “straight bourbon” requires at least two years in new charred oak, and the company itself frames Little K against that benchmark. Little K cannot be sold as bourbon, which US rules reserve for American-made whiskey. At under three years it also falls outside the voluntary standard for the term “Japanese whisky” set by the Japan Spirits & Liqueurs Makers Association in 2021. Our explainer on what counts as Japanese whisky covers that rule in detail. Future releases that pass the three-year line could, depending on their other details, start to qualify, and that will be worth watching.
The wheated mash bill is the other signal. In Kentucky, swapping rye for wheat is an established style associated with softer, rounder bourbons. Trying it this early suggests Water Dragon wants a range, not a single house spirit. Our comparison of Japanese whisky and bourbon explains why grain choice and new oak matter so much more in the American tradition. Water Dragon is not the only Shizuoka producer drawing on North American methods. Kirin’s Fuji Gotemba distillery, a short drive up the slopes of Mount Fuji, has long made grain whisky with techniques it learned from its former partner Seagram.
Finally, the sales model is unusual. Whiskey&Co. sells its own brand at retail only within the Mishima area, defined as the city plus a 500-meter band beyond its borders, under the slogan “born in Mishima, raised in Mishima, sold in Mishima.” Bars and restaurants anywhere in Japan can stock it as a trade product. Outside Mishima, the only direct retail route is through “key3” tokens the company issues on FiNANCiE, a Japanese token-based crowdfunding and community app. Holders get priority online access, with one bottle of the 23-month release per 1,000 tokens held. It is a deliberate bet on local tourism and a small, committed community rather than national distribution.
For readers outside Japan
The announcement mentions no export plans, and the retail rules mean neither bottle will appear on shelves in the US, UK or elsewhere. We have not confirmed whether non-residents can take part in the token program, and the release says nothing about international shipping. We would not plan on that route.
The realistic way to try Little K is to go to Mishima, which is a stop on the Tokaido Shinkansen and roughly an hour from Tokyo. Bottle reservations at the distillery open on October 12, with retail sales at the distillery and at participating Mishima shops from November 11. Visitors can taste “Little K 2026 2nd” on the distillery tour from October 12; the tour runs 60 to 90 minutes and costs 3,300 yen, with a tasting set that includes Little K and four of the company’s gins. From October 16, both new releases will be poured at Bar Water Gate, the bar attached to the distillery. If you cannot get to Mishima, ask at whisky bars in Tokyo. Little K is sold to the trade nationwide, so a bar that already carries it may stock the new editions after launch. Our guide to buying Japanese whisky in Tokyo lists good starting points.
Shizuoka also makes an easy two-distillery trip. The Shizuoka distillery in the mountains north of Shizuoka City now runs tours with a multilingual audio guide, and it offers a Scotch-style counterpoint to Water Dragon’s bourbon approach. For something Japanese, grain-led and actually exported, our grain whisky explainer covers the bottles you can buy abroad today.
