Saburomaru Distillery: Hokuriku's Oldest Whisky Distillery Where Tradition Meets Innovation
Nestled amid the tranquil scattered-settlement landscape of the Tonami Plain in Toyama Prefecture, Saburomaru Distillery stands as a remarkable testament to the resilience and ingenuity of Japanese craft whisky. As the oldest whisky distillery in the Hokuriku region, this facility has been producing spirit since 1952, carrying forward a legacy that began with its parent company, Wakatsuru Shuzo, a sake brewery founded in 1862. In March 2025, the distillery building was recommended for registration as a National Registered Tangible Cultural Property, recognizing both its architectural significance and its enduring role in Japan's whisky heritage.
Historical Background: From Sake Brewery to Whisky Pioneer
The story of Saburomaru Distillery is deeply intertwined with the history of Wakatsuru Shuzo. The sake brewery was originally established in 1862 during the late Edo period. In 1910, the first Kotaro Inagaki took over the brewing business, and in 1918, the company was formally incorporated as Wakatsuru Shuzo Co., Ltd.
In the aftermath of World War II, severe rice shortages made sake production extremely difficult. Seeking alternative ways to produce alcohol, the second-generation president Kotaro Inagaki turned his attention to whisky. In 1947, the company established the Wakatsuru Fermentation Research Laboratory to study distilled spirits, and in 1952, it obtained a license to produce whisky. The following year, Wakatsuru launched its first whisky brand, "Sunshine Whisky," which would become a beloved local spirit for over seven decades.
The distillery building itself has a fascinating origin. It was originally constructed as a factory for Nachi-Fujikoshi Corporation in Toyama City during the early Showa period. In 1954, the building was relocated and repurposed as a whisky distillation facility — making it the oldest whisky distillery in the Hokuriku region. However, soon after production began, a devastating fire struck the facility, presenting a major setback that the company had to overcome.
For decades, Saburomaru operated quietly, producing whisky alongside sake. But as domestic whisky demand declined sharply in the late 20th century, the distillery's operations were drastically scaled back. The turning point came in 2016, when fifth-generation family member Takahiko Inagaki returned to his hometown of Toyama, determined to revive the distillery. Through a crowdfunding campaign that raised nearly 40 million yen — far exceeding its original goal — the distillery was renovated and relaunched in 2017 under the name "Saburomaru Distillery."
Why Saburomaru Distillery Is a Registered Cultural Property
On March 21, 2025, the Council for Cultural Affairs recommended to the Minister of Education that three buildings at Wakatsuru Shuzo, including Saburomaru Distillery, be registered as National Registered Tangible Cultural Properties (buildings). The distillery was recognized under the criterion of contributing to the nation's historical landscape.
The distillery building is architecturally notable for its kingpost truss roof structure, a hallmark of early Showa-era industrial architecture. Rows of continuous windows along each level were designed to maximize natural light for factory operations. Its distinctive tile roof and white-plastered walls give it an appearance unusual for a whisky distillery, evoking the aesthetic of traditional Japanese architecture rather than the typical industrial facilities associated with spirits production.
Beyond its architectural value, the building is significant as an active whisky distillery that has been in continuous operation since 1954, making it one of the longest-operating whisky production facilities in Japan. It also serves as a visitor attraction, drawing approximately 30,000 to 40,000 visitors annually who come to learn about the whisky-making process.
Highlights and Attractions
ZEMON: The World's First Cast Pot Still
The most distinctive feature of Saburomaru Distillery is ZEMON, the world's first cast-metal pot still. Developed in 2019 through a collaboration between distillery manager Takahiko Inagaki and Oigo Seisakusho, a temple bell manufacturer in Takaoka City, ZEMON represents a groundbreaking fusion of Toyama's 400-year copperware tradition with modern whisky production. The still is made from a copper-tin alloy (approximately 90% copper and 8% tin) and was created using the same casting techniques used to make Buddhist temple bells (bonsho). ZEMON has been patented in both Japan and the United Kingdom, and received the Minister of Economy, Trade and Industry Award in 2020.
The casting process creates microscopic surface irregularities on the interior of the still, increasing the surface area and enhancing catalytic reactions with the copper. This, combined with the tin content, produces a distinctively smooth, rich spirit. ZEMON also offers practical advantages: its thicker walls (over 10 mm compared to the typical 5 mm) provide double the lifespan of conventional stills, and its superior heat retention allows it to distill significantly more spirit using the same amount of energy.
The Ultimate Peat: Saburomaru's Smoky Character
Since its founding, Saburomaru has been committed to producing peated whisky — a rarity among Japanese distilleries. The distillery's philosophy, "The Ultimate Peat," reflects this dedication to crafting deeply smoky expressions. Since 2020, the distillery has used a blend of Islay peat-smoked malt from Scotland and non-peated malt grown in Toyama Prefecture, creating a unique flavor profile that bridges Scottish tradition with Japanese terroir.
Sanshiro Barrels: Local Mizunara Oak
In another innovation rooted in regional craftsmanship, Saburomaru developed the "Sanshiro Barrel," made from Toyama Prefecture-grown mizunara (Japanese oak). These barrels are produced in collaboration with local woodworking specialists in the Inami district of Nanto City, an area renowned for its centuries-old tradition of fine woodcarving. Mizunara wood is highly prized internationally and known as "Japanese Oak" in the whisky world.
Distillery Tours and Tasting
Visitors can experience guided tours of approximately one hour that take them through the entire whisky-making process, from mashing and fermentation to distillation and maturation. The tour includes viewing the iconic ZEMON stills, the wooden washbacks, and the maturation warehouse, where an innovative roof sprinkler system uses local groundwater to regulate temperature. Tours conclude with a tasting session featuring four different expressions. On the same premises, the Taisho-gura Shop offers whisky and sake products for purchase, while the restaurant "Kamado flamme Sumisaburo" serves meals paired with the brewery's spirits (reservation required).
Award-Winning Whiskies
Saburomaru's whiskies have earned international recognition. At the World Whisky Awards (WWA) in 2023, "THE SUN 2022" won both a Gold Medal and Category Winner in the Best International Blended category. At the Tokyo Whisky & Spirits Competition (TWSC), the distillery has received multiple gold medals and special awards, including the Tourism Award for its commitment to welcoming visitors and the Innovation Award for the development of ZEMON.
The distillery's flagship single malt series follows a tarot card theme, beginning with "Saburomaru 0 THE FOOL" in 2020, symbolizing a fresh start. Subsequent releases have continued to explore the distillery's evolving character as its ZEMON-distilled spirit matures.
Surrounding Area and Nearby Attractions
Saburomaru Distillery is located in the heart of the Tonami Plain, one of Japan's most distinctive rural landscapes, characterized by its "scattered settlement" (sankyoson) pattern where individual farmhouses are surrounded by trees and rice paddies. The area offers several attractions worth exploring:
- Tonami Tulip Park — One of Japan's largest tulip gardens, hosting the annual Tonami Tulip Fair every spring with over 3 million flowers in bloom.
