Azumino Wasabi: Japan's Top Wasabi Fields Nurtured by North Alps Spring Water

Azumino is a peaceful region in central Nagano spreading at the eastern foot of the North Alps. Among its sights, Daio Wasabi Farm is known nationwide as one of Japan's largest wasabi farms. The clear stream nurtured by North Alps snowmelt, together with the beautiful scenery of wasabi fields spreading in every direction, forms a landscape unique to Azumino that soothes visitors.

Highlights

Daio Wasabi Farm is a sightseeing wasabi farm covering about 15 hectares, roughly the area of 11 Tokyo Domes. About 120,000 tons of North Alps spring water are drawn into the fields each day, with the water temperature staying steady at around 13 to 15 degrees Celsius year-round. This cold, clear water nurtures the wasabi. Visitors can stroll among the fields where clear water flows, taking in the distinctive scenery covered by black shade cloth. Within the grounds is a scenic spot where waterwheel huts stand along the stream, a popular photo point also known as a film location. Admission is free, so anyone can casually walk the wasabi fields.

Enjoying the Seasons

Early summer with dazzling fresh greenery and autumn with clear air are especially pleasant for strolling. Even in summer the water flowing through the fields is cold, making it popular with those seeking cool relief. Spring brings flowers to the surrounding fields, including apple blossoms. Across Azumino, the combination of seasonal scenery, with tulips, apple orchards, and flooded paddies, against the majestic North Alps is spectacular. In winter the quiet wasabi fields set against the snow-clad North Alps show yet another charm.

One Piece of Advice

The waterside of the wasabi fields stays cool even in summer, making it a valuable spot to escape the daytime heat. The signature wasabi soft-serve is praised for its balance of gentle spiciness and sweetness, so be sure to try it.
