Bunko-gura of the Kinshi Masamune Horino Memorial Hall: A Treasure of Edo-Period Sake Heritage in the Heart of Kyoto

Tucked behind the courtyard of a historic sake brewer's residence on Sakai-machi Street in Kyoto's Nakagyo Ward, the Bunko-gura (Library Storehouse) of the Kinshi Masamune Horino Memorial Hall stands as a quiet testament to the cultural legacy of Edo-period craftsmanship and the sake-brewing traditions of old Kyoto. Built in 1820 (Bunsei 3) as a fireproof repository for precious documents, books, and valuables, this compact yet beautifully preserved two-story earthen-walled storehouse is one of three buildings on the former Horino family estate that have been designated as Registered Tangible Cultural Properties of Japan.

Historical Background

The story of the Bunko-gura is inseparable from the history of Kinshi Masamune, one of Kyoto's most venerable sake breweries. In 1781 (Tenmei 1), the first-generation Matsuya Kyūbei, originally from Wakasa Province, founded his sake-brewing business at this very location on Sakai-machi Street, just south of Nijō. The area was once Kyoto's main commercial thoroughfare, bustling with merchants and craftsmen. The Horino family utilized the exceptional underground water source on the property — known as "Momo no I" (Well of Peach) — which shares the same subterranean water vein as the famous Somei spring at Nashinoki Shrine, one of Kyoto's three celebrated waters. This remarkably soft, pure water proved ideal for brewing refined sake.

The Bunko-gura was erected in 1820 to safely store the family's important documents, financial records, and archives related to the brewing business. A ridgepole inscription (munafuda) preserved beneath the second-floor ridge beam records that the topping-out ceremony took place on August 4, Bunsei 3 (1820), and identifies the master carpenter as Mimaki Zenbei. When the Horino family relocated their sake production to Fushimi in 1880 (Meiji 13) to take advantage of even more abundant water resources and better distribution routes, the original estate in Nakagyo was carefully maintained. In 1995, the property was opened to the public as the Kinshi Masamune Horino Memorial Hall, a museum showcasing sake-brewing heritage and traditional Kyoto townhouse culture. The memorial hall closed in July 2023, and the buildings were subsequently repurposed.

Designation as a Registered Tangible Cultural Property

The Bunko-gura was officially registered as a Tangible Cultural Property of Japan on December 4, 2000, alongside the main house (Omoya) and the Tenmei-gura (Tenmei Storehouse). The designation recognizes the compound as a rare surviving example of a sake brewer's residential estate in central Kyoto, preserving the authentic atmosphere of an Edo- and Meiji-era merchant household.

The Bunko-gura is particularly valued for its excellent state of preservation. The interior retains its original configuration almost entirely intact, offering a genuine glimpse into how wealthy merchant families protected their most important possessions in an age when fire was a constant threat. The ridgepole inscription inside provides precise documentation of the building's construction date and craftsman, adding significant historical value to the structure.

Architectural Highlights

The Bunko-gura is a compact, two-story earthen-walled storehouse (dozo-zukuri) with a total building area of just 19 square meters. Its dimensions are approximately 2.5 ken (about 4.5 meters) in both the ridge direction and the beam direction, creating an almost square footprint. The building is oriented on a north–south axis with a gabled (kirizuma) roof finished in hon-kawara (formal ceramic tiles), and the entrance faces east under an attached eave of san-gawara (pantiles).

The dozo-zukuri construction technique — thick earthen walls over a timber frame — was specifically designed to protect contents from fire, a frequent hazard in the densely built wooden neighborhoods of Kyoto. The relatively low ceiling height of the second story is characteristic of storehouses of this period, reflecting a pragmatic approach that prioritized fireproofing and structural integrity over spaciousness. The building sits west of the main residence, positioned behind the famous Momo no I well, within the inner part of the estate grounds.

The Horino Family Compound

The Bunko-gura is one of three registered cultural properties within the former Horino family estate, each representing a different function and era of the compound's history. The main house (Omoya), rebuilt during the mid-Meiji period, is a wooden two-story machiya (townhouse) with a frontage of approximately 6.5 ken (about 12 meters) and a building area of 210 square meters. It features the classic Kyoto townhouse layout with a tōri-niwa (earthen-floored corridor), shoin-style reception rooms, a chōba (merchant's office), and living quarters for resident employees.

The Tenmei-gura, built in 1864 (Genji 1), is a two-story storehouse of 70 square meters that originally served as the sake warehouse. Its construction features a distinctive central ridge-bearing pillar (munamochi-bashira) that supports the ridge beam — an archaic structural technique rarely seen in later buildings. Running south to north through the interior courtyard, the three structures — Bunko-gura, Tenmei-gura, and a former beer brewery building (Kita-gura) — together compose a remarkably complete picture of a traditional sake-brewing household in the urban core of Kyoto.

Momo no I: The Well of Peach

Central to the estate's identity is Momo no I, a natural spring that has flowed continuously on the property since the Horino family first began brewing sake here in 1781. Named after a large peach tree that once stood above it, this well draws from the same underground aquifer as the celebrated Somei spring at Nashinoki Shrine, regarded as one of Kyoto's three finest waters. The exceptionally soft, mineral-balanced water was essential to producing the delicate, refined sake for which Kinshi Masamune became renowned. Even after the brewery's main operations moved to Fushimi, Momo no I continued to be used — most recently for brewing craft beer at the on-site Kyoto Machiya Beer Brewery, which operated from 1997 onward.

Visitor Information

The former Horino family estate is located on Sakai-machi Street, just north of Nijō, in Kyoto's Nakagyo Ward. The Kinshi Masamune Horino Memorial Hall, which previously offered public tours of the buildings and grounds, closed in July 2023. The property was subsequently operated as a restaurant called Kyoto Sakagurakan Bettei from December 2023, though this establishment closed in September 2024. Visitors are advised to check the latest information before visiting, as the usage and accessibility of the property may change. The registered cultural property buildings — including the Bunko-gura — remain under the ownership of Kinshi Masamune Co., Ltd., and the exterior of the compound can be appreciated from Sakai-machi Street.

The nearest stations are Marutamachi Station on the Kyoto Municipal Subway Karasuma Line (approximately 10 minutes on foot from Exit 7) and Karasuma Oike Station on the Karasuma and Tozai Lines (approximately 10 minutes on foot). Limited free parking for up to four vehicles was available when the property was open to visitors.

Surrounding Attractions

The Horino estate is situated in the historically rich Gosho-minami (south of the Imperial Palace) neighborhood. Kyoto Imperial Palace and its expansive park lie just a short walk to the north, offering beautiful seasonal scenery and a tranquil escape. Nijō Castle, a UNESCO World Heritage Site famed for its Momoyama-period architecture and "nightingale floors," is located to the west. The Kyoto International Manga Museum, housed in a former elementary school building, is within easy walking distance to the south. Nearby Nashinoki Shrine is home to the Somei spring — sharing the same water vein as Momo no I — and is especially popular during its autumn lespedeza festival. The area is also known for its concentration of traditional craft shops, galleries, and refined Kyoto cuisine restaurants along Teramachi and Gokomachi Streets.
