In the spring fishing season comes the time when you can taste in-season Hokkaido herring at its freshest. This article brings together the Otaru herring experience in one place, from when spring herring is in season to how to buy it at the markets and the best restaurants for herring dishes.

Otaru's deep ties with herring go back to the era of huge catches from the late Edo period through the Meiji era. In spring, herring surged close to the shore in Ishikari Bay, and in 1897 (Meiji 30) the catch reached about 980,000 tons, the highest in Japan.

In the Shukutsu area, the way of life of the wealthy merchants of the time, such as the great net-owner Shiratori family, still survives in physical form. From 1884 to 1886, landings exceeded 6,000 koku every year, and a net owner's annual income is said to have topped 100 million yen in today's money. The prosperity of fishing became the economic foundation of the port town of Otaru and laid the groundwork for its growth as the gateway to Hokkaido.

From 1954 onward, however, herring numbers plummeted, and a long era of poor catches followed. Then, from 2009, kuki (gunrai) began to be observed again in Ishikari Bay, and in recent years catches have been recovering. The memory of the "herring town" remains deeply engraved in Otaru's culture and food.

When is spring herring in season? The fishing season and the gunrai phenomenon

The herring landed in Otaru and Ishikari Bay mainly belong to the "Ishikari Bay stock." This stock's spawning season runs roughly from late January to early May, and February and March, the spawning period, are considered the peak season, when the fish are at their fattiest and most flavorful.

However, the fishing season varies from year to year with water temperature and sea conditions. We cannot promise "you'll definitely be able to eat it at this time," so please check the latest information from each shop and market before your visit.

During the season, you may see the "kuki" (gunrai) phenomenon along the coast of Otaru Bay and Ishikari Bay. When herring spawn in huge schools, the sea turns milky white from the males' milt, a sight once loved as a seasonal sign announcing "the arrival of spring." For many years it was almost never seen, but since 2009 sightings in Otaru Bay have been reported again. It is not seen every year; it is a rare experience that only happens when timing and luck coincide.

Buying herring in Otaru: walking the Rinyu Morning Market and Sankaku Market

Located near the Otaru Aquarium, its trademark style is boldly grilling fresh seafood bought from local fishers over charcoal. Its famous extra-large charcoal-grilled herring can be over 30 cm long, and grilling it with nothing but salt brings out the flavor of the flesh. In spring, herring sashimi sometimes appears. It is about 10 minutes by car from the Rinyu Morning Market and the canal area.

Otaru Masazushi Main Store: A long-established shop representing Sushiya-dori, with a history of over 80 years. It is particular about seasonal ingredients, and in spring fresh fish landed in Hokkaido join the nigiri lineup. Herring is not listed on the official menu, but it may be served as a spring seasonal topping. Please ask the shop directly when you visit.

Donburi Chaya Otaru Sakaimachi-dori: Located in the Sakaimachi Street sightseeing area, this shop serves rice bowls made with seasonal seafood landed on Otaru's coast. In spring a herring bowl made with herring sent straight from the fishing port appears. Its strengths are a location that's easy to drop into while sightseeing and the freshness of its seafood. Menu details and prices vary with the season and supply, so check the official website before you go.

In 1960 it became the first Hokkaido folk house to be designated a cultural property, and it preserves and displays a bunkhouse actually used at the height of herring fishing. In fiscal 2026 (Reiwa 8) it may be closed because of slope repair work. Check the official website for the latest opening information before you go.
