Chiiori: A 300-Year-Old Thatched Farmhouse in the Heart of the Iya Valley

Nestled high on a mountainside in one of Japan's most remote and breathtaking valleys, Chiiori (篪庵) — meaning "House of the Flute" — is a remarkable Edo-period thatched-roof farmhouse that has stood for over three centuries. Located in the hamlet of Tsurui in Higashi-Iya (East Iya), Miyoshi City, Tokushima Prefecture, this former farmhouse was rescued from abandonment by American Japanologist Alex Kerr in 1973 and has since become a symbol of rural heritage preservation in Japan. Registered as a National Tangible Cultural Property in 2019, Chiiori today serves as both a cultural treasure and a unique accommodation where visitors can experience the timeless beauty of traditional Japanese mountain life.

Historical Background: From Farmhouse to Cultural Icon

Chiiori dates back to approximately 1720, during the Genroku Period of the Edo era. It was originally built as a farmhouse (minka) in the Tsurui settlement, situated along the upper reaches of the Iya River. The Iya Valley itself has a storied history — its steep gorges made it so inaccessible that over the centuries it became a refuge for those fleeing Japan's civil wars, most notably survivors of the defeated Heike clan following the Genpei War in the 12th century. The region's isolation preserved not only its traditional architecture but also traces of ancient Heian-period court language in the local dialect.

In 1971, a young Alex Kerr — then a student at Keio University — first discovered the Iya Valley during a hiking trip through Shikoku. Captivated by the dramatic landscape and the haunting beauty of its abandoned thatched houses, he returned in 1973 to purchase the old farmhouse in Tsurui. An avid flautist, Kerr named the house Chiiori, combining the Chinese character for a bamboo flute (篪) with the word for a hermitage (庵). Over the following decades, Kerr and his friends painstakingly restored the house, including a full re-thatching of the roof in the late 1980s. The house went on to feature prominently in Kerr's acclaimed book Lost Japan, bringing international attention to this hidden corner of Shikoku.

In 1999, Kerr and a group of supporters founded the Chiiori Project to promote sustainable tourism and organic agriculture in the Iya region. This initiative was formally registered as the NPO Chiiori Trust in 2005, and in 2012, Chiiori underwent a comprehensive restoration — its roof was re-thatched, structural repairs were completed, earthquake protection was incorporated, and modern amenities including plumbing, a bath, heating systems, and lighting were carefully integrated while preserving the house's historic character.

Why Chiiori Was Designated a Cultural Property

Chiiori was registered as a National Registered Tangible Cultural Property (国登録有形文化財) on September 10, 2019. The designation recognizes its significance as a representative example of traditional Iya Valley residential architecture from the early-to-mid Edo period.

The official registration notes several key features that contribute to its cultural value. The farmhouse is a single-story wooden structure with a thatched hip roof (寄棟造茅葺) and a building area of 128 square meters. Its exterior walls are reinforced with hishagi bamboo cladding (ヒシャギ竹張), a distinctive regional construction technique. The interior follows a traditional three-room layout arranged from north to south: the Chanoma (living room with an earthen floor area), the Nakanoma (central room), and the Omote (formal room). The sleeping quarters are located behind the Nakanoma, while the Omote features an engawa veranda.

Standing on a scenic mountainside with commanding views across the valley, Chiiori forms a central element of the mountain village landscape. It is believed to be the second oldest extant house in the Tsurui area, after the nearby Kimura House, which holds Important Cultural Property status. The house's remarkable open interior — with no ceilings over the main rooms — reflects the historical practice of hanging tobacco leaves in the rafters to cure over the irori hearth smoke, as tobacco was a major crop in Iya during much of the Edo period.

Architectural Highlights and Charm

Chiiori's architectural appeal lies in the harmony between its rustic simplicity and dramatic spatial qualities. The most striking feature is the open ceiling structure that reveals the massive beams, rafters, and the underside of the thatched roof — all darkened to a deep, lustrous black by centuries of irori smoke. This creates an expansive, cathedral-like interior that is rare among Japanese farmhouses, where ceilings typically enclose the upper space.

The house retains two irori (sunken hearths) in its main living areas, which continue to serve as the focal points of daily life for guests. The hardwood floors, burnished by generations of use and smoke, glow warmly in the firelight. Traditional shoji sliding doors open to reveal panoramic views of the surrounding mountains and valleys, creating a seamless connection between interior and exterior spaces.

The 2012 restoration was carried out with meticulous attention to preserving authenticity while ensuring guest comfort. Modern amenities — including underfloor heating, a wooden soaking bath, contemporary plumbing, and a well-equipped kitchen — were incorporated without compromising the historic atmosphere. Entry to the house is managed through a modern touch-panel lock system, an intriguing juxtaposition of old and new that guests often find delightful.

Staying at Chiiori: A Timeless Experience

Today, Chiiori operates as a rental accommodation managed by Chiiori Alliance, welcoming guests year-round. The entire house is rented as a single unit and can accommodate up to ten people, making it ideal for families or groups of friends seeking an immersive cultural retreat.

Guests can choose to prepare their own meals in the fully equipped kitchen or arrange a catered dinner in advance. The catering service, prepared by local residents, features seasonal Iya Valley specialties such as hirarayaki (a hot pot cooked on a stone with a ring of miso paste), iwadofu (stone-pressed tofu), Iya konnyaku, soba porridge with buckwheat berries, and hearty wild boar hot pot in winter.

As night falls, the surrounding mountains plunge into complete darkness, and Chiiori glows with a warm, amber light. The silence is profound, broken only by the sounds of nature. On clear nights, the absence of light pollution reveals a spectacular canopy of stars. Alex Kerr himself recommends staying at least two nights — one evening to enjoy the local catered cuisine, and another to shop for ingredients and cook together, transforming the meal into a convivial gathering.

Visitor Information and Access

Reaching Chiiori is itself an adventure. The Iya Valley is often described as one of Japan's three most remote places, and the journey to the house involves winding through narrow mountain roads surrounded by dramatic scenery.

By car, visitors can reach the area from the Ikawa-Ikeda Interchange on the Tokushima Expressway by driving south along National Route 32 for approximately 25 kilometers (about 30 minutes). Alternatively, from the Otoyo Interchange on the Kochi Expressway, head north along Route 32 for roughly 30 minutes. A four-wheel-drive vehicle is strongly recommended, particularly in winter when the mountain roads may be covered in snow.

By public transport, travelers can take the JR train to Awa-Ikeda Station or Oboke Station, then transfer to a Shikoku Kotsu bus bound for Kubo. Disembark at the Kojima bus stop, from which Chiiori is approximately a 45-minute walk along a forest road. Many visitors fly into Kochi Ryoma Airport, which is closer to the valley than Tokushima Awaodori Airport, and then travel by train to Oboke Station (approximately two hours).

Reservations for accommodation can be made through the official Chiiori website. Guests should note that the area has limited shopping and dining options, so advance meal planning — either by bringing supplies or pre-ordering catering — is essential.
