The Furuichi Family Residence: Tanegashima's Oldest Surviving House

When carpenters dismantled this house for repairs in 2001, they were working on a building whose exact birth year was already known. A wooden ridge tag, or munafuda, found inside records that the house was raised in 1846, the third year of the Kōka era. That single inscribed board makes the Furuichi Family Residence the oldest dated dwelling still standing on Tanegashima, the long island off the southern tip of Kyushu better known today for its space center.

The house sits in the Honmura hamlet of Sakai, in the southern part of Nakatane Town near the middle of the island. It is a low, single-story timber building with a tiled roof, set back from National Route 58 among fields and trees that have been kept much as they were when the house was the working heart of a rural estate.

The Family Who Built It

The Furuichi traced their roots to Furuichi in Kawachi Province, the area that is now Habikino City in Osaka. At some point the family settled on Tanegashima and entered the service of the Tanegashima clan, the lords who governed the island for centuries. Generation after generation, the Furuichi held the post of shōya, the village headman responsible for tax collection, record keeping, and local administration on behalf of the domain.

The man who built the present house, Furuichi Gensuke, was a gōshi: a samurai who lived in the countryside and worked the land rather than residing in a castle town. Alongside his duties as headman of Sakai village, he also served as a yokome, an inspector who kept watch over local affairs. The house reflects that double identity. Officially classified as a minka, or folk dwelling, it carries the quiet dignity of a household that ranked above its farming neighbors without ever becoming a grand mansion.

A Plan Built Around Work and Reception

The residence is shaped like an L. The longer block runs along the front, and a wing projects from its north side, giving the building two clear functions under one roof. One half is the zashiki, the matted reception and living rooms where the family received guests and conducted the business of a headman. The other half is the doma, an earthen-floored space used for cooking and daily labor, the practical engine of the household.

The roof is worth a second look. The main block carries an irimoya roof at the front, a hip-and-gable form in which the lower slopes flare out on all sides while the upper part keeps a triangular gable. At the rear, however, the same block switches to a plain kirizuma gable, a simpler shape that drops straight down at the ends. The projecting north wing returns to the hip-and-gable form. This asymmetry, dressy at the front and plain at the back, is unusual enough to catch the eye and tells you something about how the builders spent their resources where they would be seen. The whole roof is now finished in sangawara, the flanged clay pantiles common across western Japan.

In numbers, the main block measures about 6.7 meters across the front and 11.1 meters in depth, while the north wing adds roughly 7.9 by 6.0 meters. These are modest dimensions for a building of such standing, and the official description sums it up well: a compact, well-organized house of middle size.

Why It Became a National Treasure of Architecture

Tanegashima has lost most of its old houses. The island lies directly in the path of typhoons that sweep up from the south each year, and timber buildings rarely survive a century and a half of salt wind and storms. By the time surveyors took stock in the late twentieth century, the Furuichi house stood out as the earliest dwelling left on the island, with its construction date fixed beyond doubt by the surviving ridge tag.

On July 12, 1994, the national government designated the Furuichi Family Residence an Important Cultural Property. The ridge tag that records the 1846 date was listed as an attached item in its own right, since the inscription is what anchors the building in history. Because the house had been lived in until recent times and the structure had aged, a full dismantling and repair project was carried out in 2001 and 2002, returning the building to its original form.

Visiting Today

The Furuichi Family Residence is open to visitors and is managed by Nakatane Town. Local volunteers often take turns staffing the site and will show you through the rooms, and there is a guestbook to sign and free Wi-Fi on hand. Step into the zashiki and you are standing in rooms that have changed little since Gensuke's day; the reception space in particular survives close to its 1846 state.

The town also uses the house for seasonal displays. In late winter, sets of hina dolls for the Girls' Festival fill the rooms, and a separate doll exhibition runs in spring with warrior dolls for Children's Day. Because the building is a working historic site rather than a fixed museum, opening hours and access to the interior can change with the season, so it is worth checking with Nakatane Town before a long trip.

Around the House

The road improvement that once threatened the setting instead became its rescue. The land around the residence was laid out as Sakai Park, the Village of History, with a short walking course linking the house to other local sights. A few minutes away, in the grounds of Toyouke Shrine, grows what is billed as Japan's tallest cycad: a single female sago palm thought to be more than six hundred years old, its trunk propped on iron supports so the weight of its many branches cannot snap it. You reach it by climbing a short flight of wooden steps past a large akō fig tree near the entrance.

Tanegashima itself is reached from Kagoshima by high-speed ferry or by a short flight to the island's airport. From the airport, the Sakai area lies south along Route 58, roughly twenty minutes by car. Visitors usually combine the house with the island's beaches, its rocket launch facilities at the southern tip, and the surf and fishing for which Tanegashima is known.
