Daio Wasabi Farm, Azumino

Daio Wasabi Farm stands as Japan's largest wasabi cultivation facility, established in 1915 and covering 15 hectares of pristine farmland in Azumino, Nagano Prefecture. The farm produces 150 tons of wasabi annually, utilizing 120,000 tons of melted snow water flowing daily from the Northern Japanese Alps at a constant temperature of 13°C. This natural spring water system provides the pure, mineral-rich conditions essential for authentic wasabi cultivation.

The farm's cultural significance extends beyond agriculture, featuring the Daio Shrine, which enshrines the spirit of ancient local hero Hachimen Daio, after whom the farm is named and who serves as its spiritual protector. The site gained international recognition when renowned filmmaker Akira Kurosawa used its iconic waterwheel as a filming location for his acclaimed movie ""Dreams,"" cementing its place in Japanese cinema history.

Visitors can explore the expansive grounds through well-maintained walking trails that wind between the wasabi fields, offering spectacular views of the surrounding Japanese Alps. The farm offers boat tours starting from 1,400 yen depending on duration, providing a unique perspective of the cultivation areas from the waterways. The on-site restaurant and shops present an extensive array of wasabi-based cuisine, from traditional wasabi soba (buckwheat noodles) and wasabi tempura to innovative creations like wasabi ice cream and wasabi wine.

Admission to the farm is free, making it an accessible attraction for all visitors. The facility is located approximately 32 kilometers north of Matsumoto in Hotaka city. Access is available by bus, taxi, or bicycle from Hotaka Station on the JR Oito Line, which is 30 minutes from Matsumoto Station. During winter months when bicycle rentals are unavailable, taxi services operate regularly from Hotaka Station, with the farm's information office able to arrange return transport to the station.
