Nagano-grown watercress is a fresh and flavorful leafy vegetable cultivated in the clear spring waters of Azumino, where snowmelt from the Northern Alps rises from the ground. Known in Japan as oranda-mizugarashi, or Dutch watercress, it has a refreshing peppery flavor with a subtle bitterness.
Watercress is traditionally served as a garnish alongside meat dishes, but its crisp texture and distinctive flavor have made it increasingly popular as an ingredient in a wide variety of Japanese dishes.
One of the defining features of Azumino watercress is the environment in which it is grown. Much of it is cultivated in areas that were once used as wasabi fields, where abundant spring water flows continuously through the growing beds.
Because the plants are nourished by naturally flowing spring water, watercress grown in Azumino is known for its fresh taste and clean texture. It is often cultivated without agricultural chemicals, and even the stems remain tender and pleasantly crisp.
In spring, the plants produce delicate white flowers. These blossoms are also edible and can be enjoyed as part of the seasonal harvest, offering another way to appreciate the natural character of this vegetable.
Watercress is remarkably versatile in the kitchen. It can be enjoyed raw in salads, lightly blanched as an ohitashi side dish, stir-fried with other ingredients, or prepared as tempura.
It is particularly delicious from winter through early spring, when its fresh flavor is at its best. Adding watercress to a Japanese-style hot pot gives the dish a vivid green color while adding a refreshing aroma and gentle peppery flavor.
Although it has long been associated with meat dishes as a garnish, watercress can be used in many different ways. Its crisp texture and distinctive flavor make it a versatile ingredient for both traditional Japanese cooking and modern cuisine.
Watercress contains a variety of nutrients, including beta-carotene, vitamins, minerals, and dietary fiber. It is also valued for its antioxidant properties and is traditionally associated with supporting a healthy appetite.
Its appeal lies not only in its nutritional value but also in its refreshing aroma and pleasantly crisp texture. Eating locally grown watercress is an easy way to enjoy some of the natural bounty of Shinshu while experiencing the distinctive flavors of the region.
Grown in the crystal-clear spring waters of Azumino and nurtured by the natural environment of the Northern Alps, Nagano-grown watercress offers a fresh taste that reflects the character of Shinshu.
When visiting Azumino, look for this locally grown vegetable and discover a side of regional cuisine that goes beyond the area’s better-known specialties. From a simple salad to a warming hot pot or crisp tempura, watercress offers a refreshing taste of the clear waters and fertile landscape of Nagano.
