Former Tono Homotsukan (Treasure Hall): A Taisho-Era Landmark in the Heart of Folklore Country

Standing quietly in the center of Tono — the city immortalized by Kunio Yanagita's celebrated Tono Monogatari (The Legends of Tono) — the Former Tono Homotsukan is a modest yet historically significant building that marked a turning point in the region's architectural history. Built in 1925 (Taisho 14), this reinforced concrete structure was the very first of its kind in the Tono area, introducing modern earthquake-resistant and fireproof construction to a landscape long defined by traditional wooden architecture. Today, the building serves as the Shinmachi Storage Facility for the Tono Municipal Museum, safeguarding the cultural treasures of this storied region.

Historical Background

The Tono Homotsukan was constructed in 1925, during the final years of the Taisho era — a period of rapid modernization and cultural ferment across Japan. In major cities, reinforced concrete construction was already becoming established following the devastating Great Kanto Earthquake of 1923, which had demonstrated the superiority of modern materials over traditional wooden buildings in resisting seismic forces. In the rural Tono region of Iwate Prefecture, however, concrete construction was virtually unknown.

The decision to build a reinforced concrete treasure hall in Tono reflected the community's desire to protect its valued cultural and historical artifacts with the most advanced building technology available. The resulting structure was a pioneering achievement — the first reinforced concrete building in the entire Tono area. It underwent modifications in 1949 (Showa 24) and again around 1980, adapting to changing needs while preserving its essential character.

Originally functioning as a treasure hall for the safekeeping of local artifacts, the building was later repurposed as the Shinmachi Storage Facility for the Tono Municipal Museum, continuing its mission of cultural preservation into the present day.

Why It Was Designated a Registered Tangible Cultural Property

On May 2, 2017, the Former Tono Homotsukan was officially registered as a national Registered Tangible Cultural Property (building). The designation recognized several key attributes of the structure:

• It is the earliest reinforced concrete building in the Tono region, representing a milestone in the area's architectural modernization.
• Its exterior features distinctive geometric design elements, particularly the recessed treatment around the windows, which gives the facade a rhythmic, decorative quality characteristic of Taisho-era architectural aesthetics.
• The interior is notable for its bold structural concept: both the first and second floors consist of single open rooms with no interior columns, the floors being supported entirely by perimeter columns along the walls. This column-free design created remarkably spacious interiors for a building of its era and scale.
• The building demonstrates the early adoption of earthquake-resistant and fireproof construction principles in a rural setting.

Architectural Highlights

With a building footprint of 96 square meters and a two-story reinforced concrete structure, the Former Tono Homotsukan is compact but architecturally accomplished. The exterior walls display geometric ornamentation, most notably the recessed window surrounds that create shadow lines and a sense of depth across the facade. This decorative approach was characteristic of the modernist-influenced design sensibilities of the 1920s, blending Western construction techniques with a restrained decorative vocabulary.

Inside, the building's most striking feature is its open-plan layout. On each floor, a single large room stretches the full width and depth of the structure, entirely free of interior columns. The structural loads are carried by columns positioned along the exterior walls only, creating an uninterrupted interior space that was ideal for the storage and display of cultural artifacts. This engineering solution was remarkably forward-thinking for a rural building of the mid-1920s.

Tono: The City of Legends

The Former Tono Homotsukan exists within one of Japan's most culturally resonant landscapes. Tono City is famous as the setting of Tono Monogatari, the landmark collection of folk tales compiled by Kunio Yanagita and published in 1910. The tales describe a world populated by kappa (water spirits), zashiki-warashi (child spirits inhabiting old houses), tengu (mountain goblins), and the beloved Oshira-sama deity — and they established Tono as the spiritual heartland of Japanese folklore studies.

The Tono Municipal Museum, to which the Former Homotsukan now belongs as a storage facility, is one of Japan's foremost folk culture museums. Its exhibitions bring the world of Tono Monogatari to life through multimedia presentations, dioramas, and an outstanding collection of folk artifacts including Oshira-sama figures and other ritual objects.

Visitor Information

The Former Tono Homotsukan is located at Shinmachi 230-2, Tono City, Iwate Prefecture, in the heart of the city center. While the building itself primarily serves as a storage facility and may not always be open to the public for interior viewing, its distinctive exterior can be appreciated from outside at any time. Visitors interested in Tono's cultural heritage should combine a visit with the nearby Tono Municipal Museum, which offers comprehensive exhibitions on the region's folklore and history.

Tono is accessible by train on the JR Kamaishi Line from Shin-Hanamaki Station (connecting from the Tohoku Shinkansen). The journey from Tokyo to Tono takes approximately three and a half hours. Within Tono, the city center is compact and walkable, with many folklore-related sites within easy reach.

Surrounding Attractions

Tono offers a wealth of cultural and natural attractions for visitors. The Tono Municipal Museum provides an excellent introduction to the region's folklore traditions. Nearby, the Tono Furusato Village recreates traditional thatched-roof farmhouses (magariya) where visitors can experience the rural lifestyle that gave birth to the folk tales. The Kappa-buchi pool, said to be home to kappa water spirits, is a charming riverside spot. Denshoen park preserves traditional buildings and offers hands-on cultural experiences. For nature lovers, the surrounding mountains and valleys offer beautiful hiking opportunities through landscapes that have changed little since Yanagita's time.
