Magaki Village Scenery in Osawa and Kami-Osawa

Walls of Bamboo Against the Japan Sea

Two small fishing-and-farming hamlets sit at the western edge of Wajima City on the Noto Peninsula, wrapped on their seaward sides by walls of vertical bamboo four to five meters tall. The settlements of Ōzawa and Kami-Ōzawa, together selected as an Important Cultural Landscape in October 2015, are the only places in Japan where this form of windbreak still encloses entire communities. The walls are called magaki, and they have shaped daily life here for centuries.

The villages occupy narrow strips of lowland where steep mountains meet the open coast. Behind each cluster of houses, terraced fields and small dry plots climb the slopes; in front, a sheltered cove holds the fishing fleet. Winter sends gales straight in from the northwest, carrying salt spray that would tear ordinary plants apart. The bamboo wall is what makes year-round life possible in such a place.

How the Magaki Are Built

The bamboo used for the walls is nigatake, a thin species harvested from the wooded slopes behind the villages. Lengths of about three meters are driven vertically into the ground side by side, packed tightly enough that the wall reads as a continuous surface from a distance. Look closely and you find the canes stop just short of touching, leaving a hairline gap that lets air pass while breaking the force of the wind.

From inside the houses, the result is a microclimate. The bamboo cuts the worst of the winter blast but does not block the air completely, and in summer the same wall casts a deep band of shade across the lanes and along south-facing walls. Behind each magaki, residents brace the structure with wooden struts and wires, since even the densest reed wall is no match for a serious storm without reinforcement.

The walls do not last forever. Bamboo set out in the open weathers and breaks within five or six years, so the villagers rebuild sections every November, working before the first heavy storms arrive. The repair is a community task, and the rhythm of cutting, hauling, and resetting bamboo each autumn is part of what holds the settlements together.

A Medieval Manor on the Coast

The earliest written mention of Ōsawa Village comes from a jitō (estate steward) document dated 1379, which records a place called Ōsawa within the coastal manor of Shitsura-no-shō. The manor was a node in the medieval Japan Sea trade carried by small coastal vessels, and the sheltered inlet at Ōzawa served as a harbor for the wider economy of the region. Kami-Ōzawa carries an older local name, Kamezo, which residents still use today.

Through the medieval and early modern periods, the population here lived as it does now: dividing time between sea and slope. Boats brought in seaweed, fish, and shellfish; the steep land behind the houses produced rice on narrow terraces and vegetables on dry plots. Compared with the rich plains further south, this was hard ground, but the combination of sheltered cove, fresh water from inland streams, and bamboo from the hillside gave the place everything a coastal village needed.

The Houses Behind the Walls

Step through one of the gaps in the magaki and the architecture inside is almost as unified as the wall outside. Gabled roofs covered in black-glazed tiles run in a low, even line along the lanes. Exterior walls are clad in ate (a local variety of hiba cedar) clapboards laid horizontally, without the vertical battens common in some other regions of Japan. Seen from above, the row of black roofs reads almost like a single dark ribbon behind the pale band of bamboo.

This visual uniformity is not the result of preservation rules imposed from outside. It reflects shared decisions about what works in this climate: tile that resists salt, ate clapboards that shed rain, and low ridges that give the wind less to grab. The houses and the walls are pieces of the same long argument with the weather.

Visiting the Hamlets Today

The two settlements lie about twelve kilometers west of central Wajima, reached by a winding prefectural road that drops down through forested ravines to the coast. Ōzawa is the larger of the two, spread across a small flat area at the mouth of a river. Kami-Ōzawa, two kilometers further west, is more linear, strung along a single line of houses against the slope. Kami-Ōzawa has held steady at roughly twenty households for over a century, an unusual stability in a region otherwise emptying out.

There are no shops or restaurants in either village. A roadside rest area with toilets is located in Kami-Ōzawa, and the Nishiho Community Center in Ōzawa is the main public facility. The January 2024 Noto Peninsula earthquake caused significant damage across this coast, and recovery is ongoing. Please check current road and access conditions before traveling, and treat the settlements as living communities rather than open-air museums. Walking quietly past the bamboo walls, leaving fences and gates undisturbed, is the appropriate way to visit.
