Shirakawa-go Ogimachi

Ogimachi is a mountain village on the Sho River in Shirakawa, Gifu Prefecture. It was selected as an Important Preservation District for Groups of Traditional Buildings on 4 September 1976 and covers 45.6 hectares. Its core is a group of gassho-zukuri farmhouses, a style found characteristically in Shirakawa-go and in Etchu Gokayama. The houses have steep, broad thatched roofs, and the space under the roof is divided into two or three floors of rooms. Hasa-goya, small farm sheds, are also scattered through the district.

When you look, pay attention to how the whole settlement is laid out rather than to a single house. Its core lies on the east (right) bank of the Sho River, where a river terrace spreads in the shape of a crescent. House plots are scattered among the fields there, and the ridges of the gassho-zukuri houses all follow the line of the river. Take in the old road, the fields with their banks and the irrigation channels as well, and you can read the whole as one farming village. What is protected is not only buildings but land that has kept its farming pattern. It also lies in one of the snowiest regions of Japan, which is worth keeping in mind.

According to the Agency for Cultural Affairs, gassho-zukuri is said to have developed with sericulture, which flourished from the middle of the Edo period, and the production of saltpeter (ensho). Once you understand the large attic rooms, usable on two or three levels, as a form that grew together with the local livelihood, the exterior looks different.

This landscape has been protected by the residents. A society to protect the natural environment of the Ogimachi settlement was founded in 1971, a survey was carried out in 1974, and the district was designated by the state in 1976. From 1977 fire-prevention work began with water cannons and hydrants, and the water cannons now number 60. According to a 2026 summary by Shirakawa Village, there have been 263 preservation repairs since the 1976 selection. Roofs are rethatched by communal work known as yui, and the society, besides reviewing proposed alterations every month, encourages yui rethatching and holds thatch-cutting events. The burying of utility lines was completed in fiscal 2010.

In 1995 the village was inscribed as a World Cultural Heritage site as the Historic Villages of Shirakawa-go and Gokayama. Because the listing is shared with Gokayama, comparing it with the villages on the Toyama side makes the differences within the same style easier to see. After the listing, traffic congestion became an issue: large vehicles were restricted inside the district in 2009, and year-round restrictions on tourist vehicles began in 2014. The village is meant to be seen on foot, so take your time, moving from the road along the Sho River up to the fields on the terrace and changing your height as you go.
