Introduction: A Window into Rural Kyushu Life

Tucked away in the mountainous Oyama district of Hita City, Oita Prefecture, the Former Yahata Family Residence (旧矢羽田家住宅, Kyū Yahata-ke Jūtaku) stands as a remarkable testament to the traditional farmhouse architecture of rural Kyushu. Designated as an Important Cultural Property of Japan in 1982, this 18th-century dwelling is the only surviving example of "kudo-zukuri" (くど造り) architecture in all of Oita Prefecture, making it an invaluable piece of Japan's architectural heritage.

Originally located in the Koitsuma area of Higashi-Oyama, the residence was carefully dismantled and relocated to its current site beside the Oyama Culture Center in Nishi-Oyama, where it was faithfully restored to its early 18th-century appearance. Today, visitors can explore this extraordinary structure free of charge and gain a deeper understanding of how farming families once lived in the mountainous interior of Kyushu.

Historical Background

The Yahata family (read "Yawata" in some sources) served as kumigashira — village-level administrators — during the Edo period (1603–1868). The family home was situated along the eastern foothills near the Oyama River, in what was formerly the village of Koitsuma in the Oyama district of Hita-gun, Oita Prefecture.

The main building is believed to have been constructed in the first half of the 18th century, during the mid-Edo period. At that time, the mountainous landscape of the Hita basin's southern rim fostered a distinctive regional building tradition. The Yahata residence reflects an era when farmers in these remote areas adapted their homes to the challenging terrain while maintaining practical layouts for daily agricultural life.

On June 11, 1982 (Showa 57), the residence was officially designated as an Important Cultural Property of Japan. It was the fourth historic residence in Oita Prefecture to receive this honor, following the Gyōtoku, Gotō, and Kamio family residences. Shortly after designation, the building was dismantled and relocated to a site adjacent to the Oyama Nature Recreation Village Center (now the Oyama Culture Center area), where it was reassembled and restored to its original form by 1984.

Why It Was Designated: Architectural Significance

The Former Yahata Family Residence was designated as an Important Cultural Property for several compelling reasons. Most notably, it is the only surviving kudo-zukuri farmhouse in Oita Prefecture and represents the easternmost example of this architectural style, which is primarily found across Kumamoto Prefecture and southern Fukuoka Prefecture.

Among the few remaining examples of the bettō (separate-building) form of farmhouse construction in the region, the Yahata residence is distinguished by its relatively early construction date and the remarkably low degree of later alterations. While the addition of a kaku-zashiki (corner parlor room) represents a more evolved feature, the structural framework of the eastern and western wings has not yet been unified — a clear indication that the building retains the original characteristics of the split-building form.

This combination of antiquity, authenticity, and regional rarity makes the residence an irreplaceable resource for understanding the development of vernacular architecture in the Kyushu region.

Architectural Highlights: The Kudo-Zukuri Style

The term "kudo-zukuri" (くど造り) takes its name from "kudo," the local Kyushu word for kamado (cooking hearth or stove). When viewed from above, the U-shaped (コの字型) roof configuration resembles the form of a traditional cooking stove, giving this architectural style its evocative name.

The main building measures approximately 11.3 meters across the front and 11.8 meters in depth. The structure features a distinctive U-shaped hip roof (yosemune-zukuri) with additional projecting sections: a southeastern extension measuring 4.0 meters by 4.0 meters with its own hip roof, and an eastern annexe. The roofing material consists of layers of thatch (kaya) as a base, with cedar bark (sugi-kawa) covering the visible exterior surfaces — a practical adaptation to the local climate and available materials.

The floor plan follows a classic Kyushu farmhouse layout. The left side of the building contains the doma (earthen-floor work area), used for cooking and farm-related tasks. The right side comprises the raised living quarters, arranged in a five-room configuration (go-ma-dori). A distinctive feature is the large gutter (toi) that runs along the seam where the roof ridges meet, above the boundary between the earthen-floor section and the formal parlor area — a structural signature of the split-building tradition.

Kyushu's vernacular residential architecture historically separated the cooking wing from the living wing into distinct structures. In the case of the Yahata residence, this parallel split-building (heiretsu buntō) form has evolved toward integration, but the two wings retain their structural independence. This transitional state is precisely what makes the building so valuable to architectural historians.

Visitor Information

The Former Yahata Family Residence is open to visitors year-round. The exterior can be viewed at any time, while interior visits are available during business hours on weekdays. Those wishing to enter the building should contact the Hita City Board of Education's Cultural Properties Protection Division in advance to arrange access.

The residence is located next to the Oyama Culture Center (formerly Oyama Furusato Museum) in Nishi-Oyama, easily accessible from the Oyama branch office of the Hita city government. From JR Hita Station on the Kyudai Main Line, take the Hita Bus bound for Tsue-tate, alight at the Oyama Shinkōkyoku-mae stop after approximately 17 minutes, and walk about 5 minutes to reach the site. For those traveling by car, the residence is approximately 15 minutes south of the Hita Interchange on the Oita Expressway via National Route 212.

Surrounding Attractions

The Oyama district of Hita City offers a wealth of experiences for visitors who wish to explore beyond the Yahata residence. The area is renowned as a major plum-producing region, famously known for the pioneering NPC (New Plum and Chestnut) movement launched in 1961. From late February to mid-March, the Ōkubo-dai and Furuya-dai plum orchards burst into bloom with approximately 9,000 plum trees, and the annual Hita Oyama Plum Festival draws visitors from across the region.

Nearby, the Hibiki Gorge (響渓谷) features dramatic cliff faces that are particularly stunning when framed by autumn foliage. The adjacent Ume-Hibiki hot spring resort offers relaxing baths with panoramic views of the gorge. The Michi-no-Eki (Roadside Station) Mizube-no-Sato Oyama provides a convenient stop for local produce, craft goods, and award-winning plum wine and pickled plums.

Fans of the manga and anime series "Attack on Titan" will be delighted to discover that Oyama is the hometown of creator Hajime Isayama. The Oyama Dam area features bronze statues of the young protagonists Eren, Mikasa, and Armin, and a dedicated museum is located at the roadside station.

The broader Hita area offers further attractions, including the beautifully preserved Edo-period merchant district of Mameda-machi, the Kangien Confucian academy site, and the atmospheric Amagase Onsen hot spring town along the Kusu River.
