The 'gassho' name is derived from the roof's resemblance to hands pressed together in prayer.
The attic space was historically used for raising silkworms because the heat from the hearth below rose into the upper floors.
The roof thatch is made of miscanthus grass and requires replacement approximately every 30 to 40 years.
The family that built the house historically held a prestigious position in the village, serving as village headmen and saltpeter traders.
The steep roof angle of 60 degrees is specifically calibrated to minimize snow accumulation and prevent structural collapse.
Rope bindings made of hemp and vines were traditionally used in construction rather than metal nails to provide flexibility during earthquakes.
Wada House is the largest and oldest surviving gassho-zukuri farmhouse in the Ogimachi village of Shirakawa-go. Designated as an Important Cultural Property of Japan, it remains a private residence while functioning as a public museum. The house features a steeply pitched thatched roof designed to withstand heavy regional snowfall and shed water efficiently. Its construction dates back to the Edo period, reflecting the architectural evolution of the local silk-production industry. Visitors can explore the living quarters on the ground floor and the vast attic space formerly used for sericulture. The structure is built primarily from sturdy Japanese zelkova and chestnut wood joined without the use of nails. It stands as an authentic representation of a traditional mountain lifestyle preserved within a UNESCO World Heritage site.
