The Main Building of the Utsuya Family Residence

Tsurutani Family Residence Main House: A Meiji-Era Merchant Home in Kaketsuka

Standing quietly along the main street of Kaketsuka in Iwata City, Shizuoka Prefecture, the Tsurutani Family Residence Main House (靏谷家住宅主屋) is a beautifully preserved example of an early Meiji-period merchant dwelling. Built around 1884, this two-story wooden structure once served as both a sake brewery and a family home, and it continues to operate today as "Tsuruya Sake Shop." Registered as a National Registered Tangible Cultural Property in 2012, the building is a tangible link to the prosperous days when Kaketsuka thrived as one of the most important port towns along the Tenryu River.

Historical Background: Kaketsuka, the "Little Edo of Enshu"

To fully appreciate the Tsurutani Family Residence, one must first understand the remarkable history of Kaketsuka. Situated at the mouth of the Tenryu River, Kaketsuka developed as a vital port town from the Muromachi period onward. The river served as a natural highway for transporting timber, rice, tea, and textiles from the mountainous interior of Nagano and Shizuoka prefectures down to the coast.

During the Edo period, Kaketsuka flourished as a major relay port connecting Osaka and Edo (modern-day Tokyo) by sea. Timber harvested in the upper reaches of the Tenryu River was floated downstream on rafts, then transferred to larger cargo ships (kaisen) for delivery to Edo's lumber markets. The wealth generated by this maritime trade earned Kaketsuka the nickname "Enshu no Ko-Edo" — the Little Edo of the Enshu region. Prosperous merchants built grand residences and warehouses, many constructed with Izu stone brought back on the return voyages of their trading ships.

The Tsurutani family were among these thriving merchants, originally operating a sake brewery that served the bustling port community. Their main house, built around 1884 during the early Meiji era, reflects the architectural traditions and commercial prosperity of this remarkable town.

Why It Was Registered as a Cultural Property

The Tsurutani Family Residence was registered as a National Registered Tangible Cultural Property (建造物) on August 13, 2012. This registration system, established in 1996 under Japan's Cultural Properties Protection Act, aims to preserve historically significant buildings that might otherwise be lost to urban development and changing lifestyles.

The residence was recognized for several important reasons. First, it is a well-preserved example of a machiya-style combined shop and residence from the early Meiji period. The building retains its original architectural character, including distinctive lattice windows on the ground floor and projecting beam eaves (dashigeta-zukuri) on both stories. Second, the interior layout — with an earthen-floored work area at the front and formal tatami rooms at the rear — authentically represents the spatial organization of a merchant household of that era. Most importantly, the building contributes to preserving the historic streetscape of Kaketsuka and serves as a living reminder of the town's prosperous past.

Architectural Highlights

The Tsurutani Family Residence is a two-story wooden structure with a gable roof covered in iron sheeting. The building measures approximately 8.8 meters across the frontage and 13.3 meters in depth, with a total building area of 117 square meters. It faces east onto the main street, presenting an elegant facade characteristic of traditional Japanese townhouses.

One of the most notable exterior features is the set of degoshi (projecting lattice windows) on the ground floor, which allowed light and air to enter while maintaining privacy — a practical design element commonly found in merchant homes. The eaves on both the first and second floors employ the dashigeta-zukuri technique, where horizontal beams project outward to support the roof overhang, creating a distinctive layered appearance along the street.

Inside, the floor plan follows a traditional tripartite layout divided from front to back. The front section consists of the doma, an earthen-floored area that originally served as the shop and workspace for the sake brewing business. Behind this lies the middle section, transitioning to the private living quarters. The rear section contains two formal tatami-floored reception rooms (zashiki), arranged side by side, which would have been used for entertaining guests and conducting business negotiations.

Visiting Information

The Tsurutani Family Residence continues to function as a private residence and business ("Tsuruya Sake Shop"), so the interior is generally not open for public viewing. However, visitors can appreciate the beautifully preserved exterior and its contribution to the historic streetscape of Kaketsuka from the public road.

The Kaketsuka district itself is well worth exploring on foot. The area retains numerous historical buildings, including several other Registered Tangible Cultural Properties. Walking through the narrow streets, visitors can sense the atmosphere of a once-thriving Edo-period port town, with traditional merchant houses, stone-walled warehouses, and the ever-present influence of the Tenryu River shaping the town's character.

By public transportation, the area can be reached by taking a bus from JR Hamamatsu Station (Bus Terminal Platform 8, Kaketsuka line, approximately 25 minutes) or from JR Toyoda-cho Station. By car, the location is accessible from the Tomei Expressway Iwata IC, heading south toward the Tenryu River mouth area.

Surrounding Attractions

The Kaketsuka area offers a wealth of historical and cultural attractions that complement a visit to the Tsurutani Family Residence.

Kibune Shrine (貴船神社) — Located just a short walk away, this is the guardian shrine of the former Kaketsuka port. Revered by sailors and shipping merchants since the Muromachi period, the shrine hosts the spectacular Kaketsuka Festival every October (third Saturday and Sunday), featuring nine ornately decorated festival floats with gold leaf, lacquerwork, and elaborate carvings. The festival music (ohayashi) is designated as a Shizuoka Prefectural Intangible Folk Cultural Property.

Soba-kiri Yaruda (蕎麦切りヤルダ) — This artisan soba noodle restaurant is housed in the former Kaketsuka Post Office (Hasegawa Family Residence), itself a Registered Tangible Cultural Property built in 1935. The original postal counter has been cleverly repurposed as a dining counter, offering visitors a unique dining experience in a piece of living history.

Kaketsuka Lighthouse (掛塚灯台) — Standing at the mouth of the Tenryu River, this lighthouse was first lit in 1897 and marks the historical importance of the Kaketsuka port. The current structure was relocated in 2002 due to coastal erosion.

Ryuyo Marine Park (竜洋海洋公園) — A family-friendly park near the Tenryu River mouth featuring an auto-camping site, athletic facilities, and panoramic views of the Enshu-nada coastline.
