Matsubara Ayu refers to ayu, or Japanese sweetfish, caught in the Mogami Oguni River, a tributary of the Mogami River that flows through Mogami Town and Funagata Town in Yamagata Prefecture.
Blessed with clean, clear water, the Mogami Oguni River is known as one of the notable rivers in the Tohoku region for wild ayu fishing. The sweetfish raised in these pristine waters are known as Matsubara Ayu.
Matsubara Ayu is particularly appreciated for its beautiful appearance, rich aroma, and delicate flavor. Its distinctive taste reflects the natural environment of the clear river where it grows, making it a special seasonal delicacy that captures the essence of summer in Yamagata.
One of the simplest and most traditional ways to enjoy Matsubara Ayu is salt-grilling. As the fish is grilled, its characteristic fragrant aroma becomes more pronounced, while the skin develops a wonderfully savory crispness.
The tender flesh flakes apart easily and has a delicate natural flavor. Salt-grilled ayu is a classic Japanese river-fish dish and allows you to fully appreciate the distinctive taste of fish raised in a clear mountain river.
With every bite, the fragrant aroma and natural umami of Matsubara Ayu come together, offering a taste of the pristine rivers and abundant nature of the Mogami region.
The best season for Matsubara Ayu is generally from July through September. During this period, visitors may have opportunities to enjoy the fish at restaurants and traditional inns around Mogami Town.
When traveling through the Mogami region, try Matsubara Ayu and experience one of Yamagata’s distinctive summer delicacies, nurtured by the clear waters of the Mogami Oguni River and the region’s rich natural environment.
