Haruibuki is an original variety of butterbur (fuki) cultivated in Gunma Prefecture. Compared with ordinary butterbur, it develops a larger number of bracts, the leaf-like structures surrounding the base of the flower. This characteristic allows growers to harvest abundant quantities of fuki-no-tō, the edible flower buds of the butterbur plant.
Because the fuki-no-tō flower buds tend to emerge in clusters, they are also relatively easy to harvest. These practical advantages have made Haruibuki a variety of interest among growers in Gunma.
Fuki-no-tō harvested from Haruibuki is a traditional Japanese wild vegetable that heralds the arrival of spring. It is known for its distinctive bittersweet flavor and rich, aromatic fragrance, and is used in a variety of dishes, including tempura and dressed vegetable dishes.
The characteristic bitterness and fragrance of fuki-no-tō are enjoyed as a seasonal delicacy from the end of winter through spring. For many people in Japan, its appearance marks one of the first signs that spring is approaching.
Haruibuki is also valued for the quality of the butterbur stalks themselves. They are known for their rich aroma and relatively soft, easy-to-eat texture. When simmered or stir-fried, they offer the refreshing fragrance and distinctive texture associated with butterbur.
The ability to enjoy both fuki-no-tō in early spring and the mature butterbur stalks later in the season is one of the special attractions of Haruibuki.
Haruibuki is a distinctive variety whose cultivation is restricted to organizations made up of agricultural producers and other growers within Gunma Prefecture. As a result, it is rarely encountered outside the prefecture and has become a particularly characteristic agricultural product of Gunma.
Carefully cultivated by local growers, Haruibuki represents a unique variety developed through Gunma’s agricultural traditions and contributes to the region’s distinctive food culture.
The main season for Haruibuki is from around February through May. In particular, early spring is an ideal time to enjoy the distinctive aroma and pleasant bitterness of freshly harvested fuki-no-tō.
From the fragrant fuki-no-tō that signals the arrival of spring to the tender and aromatic butterbur stalks that follow, Haruibuki is a rare Gunma-grown variety that allows visitors to experience the changing flavors of the season.
