Shinobu distillery: Niigata Beer’s mizunara-finished whisky

Written by

Shinobu (忍) is the whisky brand of Niigata Beer (新潟麦酒), a craft brewery founded in 1997 on the Sea of Japan coast at Echizenhama (越前浜) in Niigata city. Its Koshi no Shinobu (越ノ忍) bottles, with a large kanji and a samurai figure on the label, are easier to find in San Francisco than in Niigata. Nikkei reported in 2019 that about 90% of output was exported, and that the US took 40% of those exports. The brand calls its site the Shinobu distillery, but the core bottles are not made from spirit distilled in Niigata. Niigata Beer says so itself on its Japanese site: the blended and pure malt whiskies use raw spirit from Scotland, and the work done in Niigata is blending and finishing in Japanese mizunara oak.

This guide works from the company’s own Japanese pages and from Japanese newspaper reports to answer two questions English-language coverage skips. First, where do these bottles sit under Japan’s 2021 labeling standard? Second, what has Niigata Beer actually built in Niigata, including a second distillery in the mountain town of Aga (阿賀町) that uses hot-spring heat?

A brewer that chose not to chase booms

Takeshi Usami (宇佐美健) left a salaried job and founded Niigata Beer in December 1997. The company’s history page records a beer licence in August 1998. It says Niigata Beer was the first in Japan to be licensed to make beer by fermenting and conditioning it in the bottle. That is the Belgian method, where live yeast finishes the beer after bottling instead of the brewer adding carbon dioxide.

The company sums up its brewing view in one line: truly good beer is beer that tastes good at room temperature, and chilling it only makes it better. It also says that since its founding it has “not ridden the waves of booms.” Instead it took on small jobs one at a time, until it found it had made more than 100 different beers. That matters for the whisky story, because the traits that later defined Shinobu were already in place before 2017.

  • An export habit. Niigata Beer began exporting beer to South Korea in 2005, then sold into the US, Australia, Hong Kong and Taiwan. When the whisky arrived, the sales channels abroad already existed.
  • A no-waste model. Since 2006 the company has fed spent brewing grain to livestock. It sells the pork as “truffle pork” and describes it as raised on feed made entirely from brewery and food-factory by-products.

Usami told Nikkei in 2019 why whisky appealed. Whisky gains depth as time passes, he said, and that makes it “a challenge beer-making does not have.”

What Koshi no Shinobu actually is

Niigata Beer’s history page records a whisky licence in December 2017. Nikkei reported that it was the first whisky distilling licence ever issued in Niigata city. The first Koshi no Shinobu came out in 2018. According to Nikkei, the company imports spirit that has been aged in sherry and bourbon casks at distilleries abroad, blends it at its Niigata plant, and then gives it further maturation in Japanese mizunara casks. The company’s own business page is more specific. It says Niigata Beer uses “raw spirit from Scotland, the home of whisky” to make its blended whisky and pure malt whisky.

The name is a statement. Koshi (越) is the old name for the region that became Echigo, today’s Niigata. Shinobu comes from the verb shinobu, to endure or to bear something quietly. In brand copy reproduced by Japanese retailers, Usami says that patience and endurance matter most in making high-quality whisky, and describes whisky as “the essence of time.” That is the brand’s own framing. The practical point is that blending imported stock let the company sell whisky in 2018, rather than waiting years for spirit of its own to mature.

It sold. Nikkei reported output of 50,000 bottles in October 2019 and exports to 10 countries and regions, including France and Hong Kong. Koshi no Shinobu also won a gold medal at the San Francisco World Spirits Competition in 2019. A local magazine, TJ Niigata, noted in 2022 that the bottles are rarely seen inside Niigata prefecture itself.

The mizunara finish

Every Shinobu bottle is built around mizunara, the Japanese oak known for incense-like aromatics and for being hard for coopers to work with because it is porous and prone to leaking. Our guide to why mizunara is so difficult explains the trade-offs. TJ Niigata reported that Niigata Beer uses casks made at its own plant from domestic mizunara. Brand copy circulated by Japanese retailers says the whiskies are neither chill-filtered nor colored. We could not confirm those two points on the company’s own site, so treat them as brand claims.

The range

The table shows the Japanese retail range as listed by the Niigata liquor shop Sakenokadoya in September 2026. Export versions vary by market, and some sold abroad, such as a lightly peated pure malt, are not on this list.

Expression Type as sold ABV / size Japan retail price (tax incl.)
Koshi no Shinobu Blended (white label) Blended whisky 40% / 750ml ¥2,420 (about $16)
Koshi no Shinobu Blended Blended whisky, mizunara finish 43% / 700ml ¥3,850 (about $26)
Koshi no Shinobu Pure Malt Blended malt, mizunara finish 43% / 700ml ¥7,370 (about $50)
Koshi no Shinobu Pure Malt Mizunara 10 Blended malt, 10-year statement 43% / 700ml ¥11,000 (about $74)

Is Shinobu Japanese whisky? Reading the label under the 2021 rules

This is the question most English reviews skip. In 2021 the Japan Spirits & Liqueurs Makers Association (JSLMA, 日本洋酒酒造組合) issued a voluntary standard for its members on who may use the words “Japanese whisky.” It took full effect in April 2024 after a grace period. The core requirements are that malted grain must be used, and that mashing, fermentation and distillation must all take place at a distillery in Japan. Water must come from Japan, the spirit must mature for at least three years in Japan in wooden casks of 700 liters or less, and it must be bottled in Japan at 40% ABV or more. Our explainer on what counts as Japanese whisky covers each rule.

By Niigata Beer’s own description, the blended and pure malt use Scottish raw spirit. Spirit distilled in Scotland cannot meet the Japan distillation requirement, however long it spends in mizunara in Niigata. So those bottles fall outside the standard’s definition. The standard is industry self-regulation rather than law, and we have not confirmed whether Niigata Beer is a JSLMA member.

Requirement JSLMA standard Shinobu blended and pure malt (as described by Niigata Beer)
Where it is distilled At a distillery in Japan Raw spirit from Scotland
Where it matures At least three years in Japan Aged abroad in sherry and bourbon casks, then finished in mizunara in Niigata
Where it is bottled In Japan, at 40% ABV or more Blended and bottled in Niigata, at 40% or 43%

To be fair to the company, it does not hide the sourcing. The origin of the spirit is stated plainly on its Japanese business page, which is more than many brands built on imported stock have offered. The confusion happens further down the chain. Shops in Japan and abroad often file Shinobu under “Japanese whisky” in their menus, and that is a shelving choice, not a finding under the standard. Before paying a Japanese-whisky price for any bottle, read the back label and look for the category wording. Our guides to what world blended whisky means and how to spot a bottle that is not really Japanese whisky explain what to look for.

Tsugawa: the hot-spring distillery in Aga

The more interesting chapter is what Niigata Beer did next. In July 2021, the Niigata construction paper Nihon Kogyo Keizai Shimbun reported plans for a new distillery in Aga, a snowy mountain town along the Agano River in the east of the prefecture. The company planned to convert the former Kanose (鹿瀬) gymnasium and use heat from the Kanose hot spring. Construction was to start that August, with completion in November, operation in December and first shipments in fiscal 2022. The plan also included a cask warehouse and a cattle unit in the town, with the cattle to be fed spent malt from distillation.

The company’s history page confirms the outcome: a whisky licence for the Tsugawa (津川) distillery in November 2021. Tsugawa is the old post town at the heart of Aga.

Why a hot spring? Usami’s own explanation to TJ Niigata was about casks rather than stills. He said he looked at Akayu Onsen (赤湯温泉) because its water is among the hottest of any spring in the prefecture, and the heat can be used to control warehouse temperatures for filled casks. The two reports name different springs, and we could not reconcile them from public sources. The logic is consistent, though. Aga gets heavy winter snow, and geothermal heat lets the company decide how warm its maturing stock stays. Brand copy calls this Japan’s first, and “possibly the world’s first,” geothermally heated whisky distillery. We have not verified that claim.

The Tsugawa project also closes the loop the brewery opened in 2006, with distillation by-products going to cattle as brewing grain goes to pigs. In place of the usual story of pure water and pristine air, Niigata Beer’s link to its land is a farm-and-factory circuit. It is built on waste streams and local heat.

What about a single malt?

Niigata Beer’s business page describes a single malt made from barley, distilled twice and matured in mizunara casks. A licence dated November 2021 means spirit from Tsugawa could only have reached three years from late 2024. We could not find a dated release announcement from the company that ties a single malt to Tsugawa-distilled spirit. Some overseas shops list a “Koshi no Shinobu Single Malt,” so check the back label for where it was distilled. A single malt distilled and aged in Aga would be the first Niigata Beer whisky that could meet the Japanese whisky standard.

What this means if you are choosing a bottle

Buying Shinobu today means buying a Niigata brewer’s selection of imported whisky and its mizunara finishing, not Niigata distillate. That is a legitimate thing to buy, and it resembles Kaiyo, another mizunara-finished brand built on blending and finishing rather than distilling. The fair question is price. In Japan the 43% blend retails for about ¥3,850. The Whiskey Wash listed the blend at $53 and the pure malt at $75 in the US in 2020. At those US prices you are paying a Japanese-whisky premium for a product that the Japanese standard would not call Japanese whisky.

Published reviews are mixed rather than glowing. The Whiskey Wash’s 2020 round-up described a briny, sea-salt character in the blend and scored the pure malt higher, 4 out of 5 against 3.5. If the mizunara finish is what you want at an accessible price, the pure malt is the logical starting point. If you want Niigata-distilled whisky, wait for a dated Tsugawa release with a clear back label. Do not confuse Shinobu with Niigata Kameda distillery (新潟亀田蒸溜所), a separate company that distills its own spirit in Niigata city. Our list of every whisky distillery in Japan keeps the two apart.

Where to buy Shinobu in the US, UK and elsewhere

  • US: The US is the brand’s largest export market, according to Nikkei. Independent retailers such as Don’s Liquors & Wine and High End Liquor have listed the blend, the pure malt, a single malt and a lightly peated mizunara pure malt. For stores that carry Japanese bottles, see our guide on where to buy Japanese whisky in the US.
  • UK: We did not find a current listing at the major UK specialists when checking in September 2026. Buyers in the UK usually have to order from EU shops that ship to Britain, with duty on top.
  • EU: The German shop Delicando lists the blended mizunara finish in a gift box.
  • Canada and Australia: Canadian Liquor Store lists the blend, the pure malt and the lightly peated pure malt. The Whisky Company in Australia lists the blend.
  • Japan: Niigata liquor shops such as Sakenokadoya carry the full domestic range, and the blend also appears as a hometown-tax (furusato nozei) gift. If you are visiting Japan, the domestic prices in the table above are well below export shelf prices.

FAQ

Q: Is Shinobu whisky Japanese whisky?

A: Not under the 2021 JSLMA standard, going by the maker’s own description. Niigata Beer says its blended and pure malt use raw spirit from Scotland, which is then blended and finished in mizunara casks in Niigata. The standard requires distillation in Japan, so these bottles fall outside its definition.

Q: Who makes Shinobu whisky?

A: Shinobu is made by Niigata Beer Co., a craft brewery founded in December 1997 by Takeshi Usami in Echizenhama, Niigata city. The company also brews more than 100 beers, raises livestock on spent grain, and obtained its first whisky licence in December 2017 before launching Koshi no Shinobu in 2018.

Q: What does Koshi no Shinobu mean?

A: Koshi is the old name for the region that became Echigo, today’s Niigata prefecture. Shinobu means to endure or bear something quietly. In brand copy, founder Takeshi Usami says patience is the most important element in making high-quality whisky, which he calls the essence of time.

Q: Does Niigata Beer distill its own whisky?

A: It holds a whisky licence for a second site, the Tsugawa distillery in Aga town, granted in November 2021 and designed around hot-spring heat. The company describes a double-distilled barley single malt matured in mizunara, but we could not find a dated release tying a single malt to Tsugawa-distilled spirit.
