Rural Landscape of Tasomeso Ozaki

Tashibu no Sho Ozaki: A Living Medieval Manor Landscape

Tucked away in the southwestern foothills of the Kunisaki Peninsula in Oita Prefecture, Tashibu no Sho Ozaki is one of Japan's most extraordinary cultural landscapes — a place where rice paddies, settlements, and irrigation systems have remained virtually unchanged for over a thousand years. Designated as a nationally Important Cultural Landscape (重要文化的景観) and recognized as part of a Globally Important Agricultural Heritage System (GIAHS), this remarkable rural area offers visitors a rare glimpse into Japan's medieval agrarian past, still alive and functioning in the present day.

Unlike preserved ruins or reconstructed historical sites, Tashibu no Sho Ozaki is a living community. Local farmers continue to cultivate rice in fields whose shapes and boundaries date back to the Heian period (794–1185). The irregularly curved paddy ridges, the stone weirs built into natural bedrock, and the traditional water management practices all survive as tangible connections to a feudal estate system that once sustained one of Japan's most powerful shrines.

A Brief History: From Ancient Manor to Cultural Treasure

The history of Tashibu no Sho is deeply intertwined with Usa Jingu Shrine, one of the most important Shinto shrines in Japan. During the Heian period, following the enactment of the Konden Einen Shizai Law in 743 — which allowed private ownership of newly cultivated land — rice paddies were developed in the Tashibu Basin by local shrines and eventually by Usa Jingu itself. By the early 11th century, Tashibu no Sho had been established as a formal manor estate (荘園).

Tashibu no Sho became one of the "Hon Gosho Juhakkasho" (本御荘十八箇所) — the eighteen root estates of Usa Jingu, which at its peak controlled over 20,000 cho (approximately 20,000 hectares) of land across Kyushu. The Ozaki district served as the administrative center, home to the estate's steward (荘官), the Tashibu clan, who were descendants of Usa Jingu's priests.

During the late Kamakura period, control briefly passed to eastern warrior families, but after the Mongol invasions of 1274 and 1281, the estate was returned to Usa Jingu under the Shinryo Kogyo Ho (shrine estate recovery act), which credited the prayers of shrines and temples with repelling the invaders. The Tashibu clan subsequently maintained stewardship of the estate for centuries.

In 2010, a 92-hectare area of the Ozaki district was designated as an Important Cultural Landscape under Japan's Cultural Properties Protection Law. In 2016, an additional 520.8 hectares of surrounding satoyama (里山) — the wooded hills that sustain the agricultural ecosystem — were added, bringing the total protected area to 612.8 hectares.

Why Was It Designated? The Cultural and Historical Value

Japan's Important Cultural Landscape designation recognizes landscapes that have been shaped by the distinctive lifestyles, livelihoods, and natural environments of their communities. Tashibu no Sho Ozaki earned this distinction for several compelling reasons.

First, the land use patterns here have remained remarkably stable since the medieval period. When historical village maps from the Genroku era (late 17th century) are compared with the current landscape, the arrangement of paddy fields and settlements is virtually identical. Archaeological surveys begun in 1981 confirmed that settlement sites identifiable in Kamakura-period documents still correspond to existing farmsteads in the Daison (台薗) district.

Second, the area preserves ancient water management techniques that have largely disappeared elsewhere in Japan. Unlike modern rice paddies with concrete irrigation channels, Tashibu no Sho Ozaki uses "tagoshi kangai" (田越灌漑) — a traditional method where water flows from one paddy to the next through cuts in the earthen ridges. The stone weirs (イゼ/ize) that divert water from streams are built directly into natural bedrock and large boulders, many bearing place names found in medieval documents.

Third, the landscape represents a complete agricultural ecosystem. The satoyama forests of sawtooth oak (kunugi) surrounding the paddies serve dual purposes: they provide log wood for shiitake mushroom cultivation — a key local industry — while also functioning as natural water catchment areas that replenish the springs and streams feeding the rice paddies below. This cyclical relationship between forest and field was recognized by the FAO when the broader Kunisaki Peninsula and Usa region was designated a Globally Important Agricultural Heritage System (GIAHS) in 2013.

Highlights and Things to See

Nearby Attractions

Tashibu no Sho Ozaki lies at the heart of the Kunisaki Peninsula's extraordinary concentration of cultural and religious heritage sites. Several nationally significant properties are located within a short drive.

Fukiji Temple (富貴寺), just a few kilometers north, houses one of Japan's National Treasures — the Oido Hall, the oldest surviving wooden structure in Kyushu, dating to the late Heian period. Built entirely of Japanese nutmeg-yew wood, it is counted alongside Kyoto's Byodoin Phoenix Hall and Hiraizumi's Konjikido as one of Japan's three great Amida halls.

Maki Odo (真木大堂), situated adjacent to the Tashibu area, preserves nine Important Cultural Property Buddhist statues from the Heian period, including the largest Daiitoku Myoo (Great Awe-Inspiring Wisdom King) sculpture in Japan, depicted riding a white water buffalo.

Kumano Magaibutsu (熊野磨崖仏), to the south, features two colossal cliff-carved Buddhist figures — an 8-meter Fudo Myoo and a 6.7-meter Dainichi Nyorai — among the oldest and largest stone Buddha carvings in Japan. The approach involves climbing a dramatic stone stairway said to have been built by demons in a single night.

The Kunisaki Peninsula Long Trail passes directly through Tashibu no Sho, connecting these sites along ancient pilgrimage routes that monks have walked for over 1,300 years as part of the Rokugo Manzan peak-entry practice (峯入り).

Getting There

Tashibu no Sho Ozaki is located in Bungotakada City, Oita Prefecture. The area is best accessed by car, as public transportation options are limited. From Oita Airport (located on the Kunisaki Peninsula), the drive takes approximately 40 minutes. From JR Usa Station on the Nippo Main Line, the journey is about 30 minutes by car. Oita Kotsu operates a sightseeing bus tour covering major Kunisaki Peninsula sites including Usa Jingu, Fukiji Temple, Maki Odo, Kumano Magaibutsu, and Futagoji Temple, departing from Oita Station and Beppu Station.

Parking is available at Hotaru no Yakata (approximately 15 spaces, with large bus access) at Tashibu Ozaki 2596, Bungotakada City. Visitors should wear comfortable walking shoes, as exploring the paddy paths involves walking on uneven earthen trails.
