Ayu, a familiar fish in mountain streams and rivers.

With their simple yet deep olive color and prominent "oi-boshi" (yellow spots), they have been cherished since ancient times as a representative fish of summer in Japan.

In the world of fishing, "ayu no tomotsuri" (decoy ayu fishing) using live decoy ayu is deeply enjoyable and is celebrated as a premier method of ayu fishing.

Imagine these wild fish living in harmony with nature.
