Yokoyama Sake Brewery Shop: A Taisho-Era Kanban Architecture Gem in Nanbu Town
Nestled at a distinctive Y-shaped intersection in the heart of Nanbu Town, Yamanashi Prefecture, the Yokoyama Sake Brewery Shop (横山酒造店店舗) stands as a remarkable example of kanban kenchiku — a uniquely Japanese architectural style that blends Western facade design with traditional wooden construction. Built around 1916 during the Taisho era, this three-story wooden building has served as both a sake shop and family residence for over a century, earning its registration as a national Registered Tangible Cultural Property in August 2016.
A Living Legacy of Taisho-Era Architecture
The Yokoyama Sake Brewery was founded in 1917 (Taisho 6) by the first-generation owner, Waichi Yokoyama, in the southern tip of Yamanashi Prefecture. The brewery is known for producing "Hinode-giku" (日の出菊), a sake praised for its well-balanced flavor, body, and aroma — qualities attributed to the pristine natural environment of the Nanbu area.
The shop building itself predates the brewery's founding by one year, having been constructed around 1916. Originally built as a two-story wooden structure, the building underwent significant transformations over the decades. When road-widening projects in the early 1950s cut into the front of the property, the owners compensated for the lost floor space by adding a third story around 1953, followed by a one-bay extension on the west side in the mid-1950s. Despite these successive modifications, the building maintains a harmonious architectural character that tells the story of its evolution.
Why It Was Registered as a Cultural Property
The Yokoyama Sake Brewery Shop was registered as a national Registered Tangible Cultural Property (建造物) on August 1, 2016. Several distinctive features contributed to this recognition.
The building occupies a triangular plot of land wedged between converging streets — an unusual site that the architects filled almost entirely with the structure. Its street-facing exterior walls feature a faux-stone (giseki) finish that gives the wooden building the imposing appearance of a stone structure. The upper portion of the facade incorporates elegant curved lines in a parapet-style design, characteristic of the kanban kenchiku (signboard architecture) style that emerged in Japan during the early 20th century.
Inside, the building presents a fascinating interplay of Japanese and Western design elements. The ground floor retains the atmosphere of a traditional machiya (townhouse), with thick pillars and exposed beams. The corridor ceilings feature Western-style skylights, while the bathroom ceiling employs sukiya-style design using natural materials. The eaves of the third-floor hip-and-gable (irimoya) roof display Western-influenced decorative moldings.
The quality of the plastering work — both on the exterior walls and around interior ceiling light fixtures — has been noted as particularly outstanding. Despite the many renovations and additions over the years, the building shows remarkably little structural distortion, and the irregular sections are skillfully integrated.
Highlights and Architectural Features
The Kanban Kenchiku Facade
Kanban kenchiku, or "signboard architecture," is a distinctive Japanese building style where the front of a wooden structure is given a flat, vertical facade reminiscent of Western stone or brick buildings. The Yokoyama Sake Brewery Shop exemplifies this style with its faux-stone exterior walls and curved parapet top. Unlike the traditional Japanese approach of extending eaves outward, the facade rises vertically — a design influence from Western architecture that arrived in Japan during the Meiji period.
The Harmonious Blend of Japanese and Western Design
One of the building's most compelling qualities is how naturally it combines Japanese and Western aesthetics. The ground-floor shop area maintains the feel of an Edo-period merchant house, with its sturdy timber framework. Moving deeper into the building, visitors encounter the sukiya-style elegance of the bathroom ceiling, crafted with natural materials. Western design appears in the corridor ceiling skylights and the eave moldings — creating a seamless fusion that reflects the Taisho era's spirit of cultural openness.
The Triangular Plot
The building's triangular footprint, dictated by the Y-shaped intersection on which it sits, gives it a distinctive silhouette visible from multiple angles. This unusual shape adds character to the streetscape and demonstrates the ingenuity of the builders who maximized every available square meter of the 103-square-meter site.
Nanbu Town: The Birthplace of the Nanbu Clan
Nanbu Town sits at the southernmost tip of Yamanashi Prefecture, straddled by mountains and bisected by the Fuji River — one of Japan's three most rapid rivers. The town has a rich history as a post town along the Sunshu Kaido highway and as a thriving hub during the era of Fuji River boat transport.
Nanbu Town is also historically significant as the birthplace of the Nanbu clan, a powerful samurai family originally from Kai Province (present-day Yamanashi) that later established dominance in the Tohoku region during the Kamakura period. The Michi-no-Eki Nanbu roadside station features an exhibition room dedicated to the Nanbu clan's history.

It features a flat, vertical facade applied to the front of a traditional wooden building, giving it the appearance of a Western-style stone or brick structure. The facades were typically covered with copper sheets, tiles, or mortar. This style became popular in shopping districts across Japan as a way to project a modern, fire-resistant image while maintaining traditional wooden construction behind the facade.

- Hinode-giku (日の出菊) is the signature sake brand produced by Yokoyama Sake Brewery. Availability may vary, so it is advisable to inquire locally. You may also find Hinode-giku sake at the Michi-no-Eki Nanbu roadside station or other local shops in the area.
