Hamoto Family Main Building

Hamoto Family Residence Main House: A Meiji-Era Merchant Townhouse in Yamatokoriyama

Nestled along the historic highway that once connected Yamatokoriyama Castle town to the ancient capital of Nara, the Hamoto Family Residence Main House (葉本家住宅主屋) stands as a distinguished example of early Meiji-period merchant architecture. Located in the Nishi-Kannonji-cho district of Yamatokoriyama City, Nara Prefecture, this well-preserved townhouse offers visitors a rare glimpse into the daily life and commercial culture of a prosperous merchant family during one of Japan's most transformative eras.

Registered as a Tangible Cultural Property of Japan in August 2002, the Hamoto Residence is recognized not only for its architectural merit but also for the role it plays in preserving the historic streetscape of this storied castle town. With only a handful of traditional machiya remaining along this stretch of the old Kannonji highway, the Hamoto house is an invaluable piece of Japan's architectural heritage.

Historical Background

The Hamoto family has a long and storied connection to the commercial life of Yamatokoriyama. During the Meiji period, the family operated a ryōgae-ya — a money-changing business — as evidenced by the distinctive fundō (balance weight) motif that adorns the mushiko-mado latticed windows on the upper story. This emblematic design served as a visual signboard, instantly communicating the family's trade to passersby on the busy highway. In later years, the family transitioned to operating a fertilizer business, reflecting the shifting economic landscape of the region.

The main house is estimated to have been built in the early Meiji period (circa 1868–1911), a time when Japan was undergoing rapid modernization while still holding firmly to its traditional building techniques. The residence stands as a testament to this transitional era, embodying centuries of accumulated craftsmanship in Japanese residential architecture.

Yamatokoriyama itself boasts a rich history stretching back to the Sengoku period, when Tsutsui Junkei built Koriyama Castle in 1580. The castle town flourished further under Toyotomi Hidenaga, the younger brother of Toyotomi Hideyoshi, who transformed it into a grand castle befitting a million-koku domain. The town prospered as a key junction on the Nara Highway and remained an important political and cultural center throughout the Edo period under the Yanagisawa clan.

Why It Was Designated a Cultural Property

The Hamoto Family Residence Main House was registered as a national Tangible Cultural Property (Registered Tangible Cultural Property — Buildings) on August 21, 2002. The designation recognizes several key attributes of the building.

The residence faces east along the old highway running from the Yamatokoriyama castle town toward Nara. It is a merchant house built in the kirizuma-zukuri (gable roof) style with a hirairi entrance — meaning the main entrance is on the long side of the building, typical of machiya townhouses. The structure features a tsushi two-story design with a kemuri-dashi (smoke vent) and a pantile roof (san-kawara-buki).

Its refined exterior is composed of several hallmark features: delicate degoshi (projecting lattice windows) and battari shōgi (fold-down benches) on the ground floor, and elongated mushiko-mado (insect-cage windows) on the upper story. Together, these elements create a beautifully balanced façade that contributes significantly to the historical landscape of the former highway.

The building is one of only a few remaining machiya along this section of the Kannonji highway. Although some modifications have been made over the years, the overall state of preservation is excellent, making it an invaluable resource for understanding the townhouse architecture of this region and period.

Architectural Highlights and Craftsmanship

The Hamoto Residence is remarkable not only for its streetside appearance but also for the exceptional craftsmanship found within. The floor plan follows the traditional machiya layout: a tōri-doma (running earth-floor corridor) extends along the southern side, while six rooms are arranged on the northern side. The two rooms at the front are designed to be smaller, creating space for a tsuboniwa — a compact courtyard garden that brings light and air into the heart of the building.

The roof is covered with san-kawara (pantiles) and features a subtle mukuri — a gentle convex curvature that gives the roofline an elegant, softly swelling silhouette. This refined detail is characteristic of high-quality residential architecture of the period.

One of the most notable aspects of the residence is the involvement of Kawasaki Chōshichi, the grandfather of the renowned Yamato sashimono (joinery) master Kawasaki Yūgen. Kawasaki Chōshichi contributed to the construction of the house and personally crafted the tategu (fittings), ranma (transom carvings), and a tea room within the residence. His distinctive artistry is visible in several features, including the Narihira-gōshi lattice work, the elegantly detailed rafters of the tsuboniwa, and the ingenious corner-turning amado (rain shutters) at the building's inner corners.

Kawasaki Yūgen (whose given name was Osamu) went on to become one of Nara's most celebrated sashimono craftsmen, continuing a family tradition of exceptional woodworking that spanned generations. His grandfather's contributions to the Hamoto Residence serve as an early showcase of the family's extraordinary skill.
