Flowing through western Shimane Prefecture, the Takatsu River is a Class A river and the only one in Japan with no dams—a miraculous pristine stream. From this river, which has repeatedly ranked first in water quality assessments by the Ministry of Land, Infrastructure, Transport and Tourism, comes a luxurious culinary experience that delivers nature’s ultimate gifts directly to your body.
Wild Ayu from the Takatsu River (Season: June–September) | Rod Fishing Season Opens: May 27, Reiwa 8
A masterpiece born of pure waters
● Raised on high-quality moss growing on the undammed riverbed, one bite releases a refreshing, noble sweetness reminiscent of watermelon or cucumber. Beyond its fragrance, it boasts exceptional umami and texture (flesh quality).
● Local restaurants serve elegant sashimi called "se-goshi," where the refreshing aroma and subtle bitterness bloom, as well as the classic "salt-grilled" version, enjoyed whole from head to tail. Crispy on the outside, tender and flaky within. The simplicity of preparation highlights the superior quality of Takatsu River ayu, transforming even the concept of grilled fish.
Wild River Crab (Mokuzu-gani) (Season: Early summer to autumn) | Fishing Period: August 1 – October 10
The hidden delicacy known only to connoisseurs—"the river’s Shanghai crab"
● A relative of the premium Shanghai hairy crab, this luxurious local specialty has long been cherished in the region. Raised in Japan’s cleanest river environment, it lacks the muddy taste typical of river crabs. The richness and depth of its crab miso are said to surpass even the original Shanghai crab.
● As a reward for your hard work, enjoy spoonfuls of exquisite crab miso with a glass of local sake. The regional specialty dish "kani-jiru," made by mashing the crab to extract its broth, is an inner-beauty soup that warms and nourishes your entire being.

Kamoshima Clam (Season: Spring to around October)
A miracle in just 1.5km—the Venus of the sea
● The native Japanese clam found only in a 1.5km estuary where the pure freshwater of the Takatsu River meets the rough waves of the Sea of Japan. Under strict resource management, only a limited number of fishermen can harvest it, making it an ultra-rare brand consumed almost entirely locally.
● Plump, thick flesh and an intense, overflowing essence. Packed with zinc and taurine—nutrients beloved by women—this is truly a "mythical gift from the sea" that delights the body.
