Savoring the Springs: Inside Gero Onsen’s 2026 Masu-Zake Walk and the Centuries-Old Breweries Crafting Hida’s Liquid Gold

Executive Overview

From September through the end of October 2026, the historic hot spring town of Gero Onsen in Gifu Prefecture, Japan, is hosting one of its most anticipated seasonal tourism events: the Gero Onsen Masu-Zake Walk. Merging the tactile traditions of Japanese woodwork with the refined artistry of mountainous brewing, the event invites visitors to strap on comfortable walking shoes, carry a traditional masu (wooden drinking box), and embark on a self-guided architectural and culinary pilgrimage through the town.

Ten distinct establishments—ranging from time-honored ryokan-cafes and local liquor shops to specialty dining destinations and relaxed afternoon bars—are participating in the 2026 program. Utilizing an innovative digital ticketing system, participants receive four digital vouchers per sake set, empowering them to curate their own tasting routes from a diverse menu of ten unique expressions. Far exceeding the boundaries of conventional Junmai Daiginjo selections, this year’s lineup showcases the astonishing versatility of Hida’s craft producers. It features unrefined doburoku, aromatic shochu, internationally decorated gold-medal competition brews, and even a historic 55% ABV rice-based vodka that once graced diplomatic tables during a Russian presidential visit.

This comprehensive report examines the roots of the event, the storied heritage of its principal brewing partners—Tenryo Shuzo and Oku Sake Brewery—and a venue-by-venue breakdown of the exquisite local pours defining the autumn 2026 calendar.

Detailed Chronology & Event Mechanics

The Masu-Zake Walk operates on a seamless fusion of analog heritage and modern convenience. Running continuously from September 1 to October 31, 2026, the program is designed to disperse foot traffic evenly throughout Gero Onsen’s atmospheric alleyways, encouraging travelers to look beyond the steam rising from its famous public footbaths and engage directly with local merchants.

The Digital Ticketing Revolution

Participants purchase a tasting set that includes a commemorative wooden masu and four digital tickets. Rather than being locked into a rigid tour group or pre-set tasting flight, guests leverage their smartphones to map out personal itineraries across the ten participating venues.

With ten distinct pours available across the network, the system encourages strategic decision-making. Should a visitor opt for a velvety, low-alcohol innovation designed for slow sipping, or pursue the intensely coveted, limited-edition gold-medal contest winners produced exclusively for professional appraisal panels? The freedom of choice transforms a standard tasting event into an interactive treasure hunt through Gero’s hospitality landscape.

The Master Brewers: Centuries of Hida Craftsmanship

The exceptional quality underpinning the 2026 Masu-Zake Walk is a direct result of the geographic and cultural conditions of the Hida region. Flanked by pristine mountain ranges, Gero benefits from abundant, soft subterranean water sources and fertile soil capable of yielding exceptional sake-brewing rice varieties, most notably Hidahomare. Two venerable institutions anchor this year’s offerings: Tenryo Shuzo and Oku Sake Brewery.

Tenryo Shuzo: Innovation Rooted in 1680

Established in 1680 in Hagiwara-cho, just north of Gero Onsen proper, Tenryo Shuzo has spent more than 340 years refining its craft. While deeply respectful of historic precedents, the brewery has cultivated a reputation for fearlessly challenging industry norms.

A prime example of this progressive mindset is the introduction of "ANDANTE" for the 2026 season. Engineered with a modest 10% alcohol-by-volume (ABV), ANDANTE was developed to challenge the notion that fine sake must always be heavy or high-proof. By offering a light, refreshing profile reminiscent of a crisp white wine while retaining the profound umami of Hida rice, Tenryo has engineered an ideal companion for the casual wanderer.

Oku Sake Brewery: Four Consecutive Gold Medals

Further south in Kaneyama Town—a historic post town where the Hida and Maze rivers converge—Oku Sake Brewery has been operational since 1720. Utilizing the pristine groundwater running through the district, Oku crafts flagship labels like "Oku" and "Hatsumidori."

Oku’s dedication to technical mastery was underscored in 2026 when the brewery secured a Gold Medal at the All Japan New Sake Appraisal Competition for the fourth consecutive year. Beyond traditional brewing, Oku holds a rare distinction: it obtained a commercial vodka production license as early as 1959. This unique duality—balancing ultra-refined competition-grade Daiginjo with avant-garde distilled spirits—demonstrates an uncommon breadth of technical expertise.

Venue Profiles and Featured Pours

The ten participating stops along the 2026 Masu-Zake Walk map out a diverse culinary narrative, pairing regional delicacies with carefully selected pours.

• Profile: A long-established restaurant and cafe offering classic set meals, local noodle dishes, and regional Gero specialties.
• Featured Pour: "Tsukiyo no Shirasagi Junmai Daiginjo" (Moonlit White Heron).
• Context: Gero Onsen owes its discovery to a legend involving a wounded white heron that revealed the healing waters to local villagers. Fukiya’s featured sake features a label commemorating this founding myth. Brewed with Hyogo-grown Yamada Nishiki rice polished down to 35%, it delivers an impeccably smooth finish and an aroma as ethereal as the tale that inspired it.
