herring — the fish that built Hokkaido's coastal fortunes
The fish behind Hokkaido's 'herring mansions', built on booming catches from the Meiji era into early Showa. Its roe is kazunoko, and a history of shoals so dense spawning turned the sea white lives on in dried mikaki-nishin preservation.

Lineage
What it's made of
A fish landed in staggering volumes from the Meiji era into early Showa, its roe becoming kazunoko, a New Year staple. The flesh itself is fatty white meat, and dried migaki-nishin releases concentrated flavor with every chew, while nishin simmered sweet and slow turns soft enough to eat bones and all. It peaks in early spring as shoals approach shore to spawn, both fat and roe at their fullest.
How it's made
The core method nets an entire shoal as it approaches shore to spawn, and catches once ran so far beyond what could be processed fresh that drying it into migaki-nishin became standard for preservation. How long it's dried changes the texture, with longer drying said to concentrate more flavor. The roe is brined separately into kazunoko, processed apart from the flesh entirely.
Why it took this shape
Off the coast of Otaru in Hokkaido, herring once arrived in shoals so dense during spawning season that their milt is said to have turned the sea white — a phenomenon called kuki. That boom brought wealth to the coast, and the preservation craft it required, like migaki-nishin, survives today alongside the herring mansions it built. The sheer scale of those shoals is what shaped the fish's whole story here.
Before you go
- How to shop at a supermarketHow to choose prepared foods, sashimi, and packaged sushi, when discount stickers tend to appear, region-only specialties, buying by weight, the checkout and bagging flow, and sampling etiquette at a local supermarket.
- Roadside stations, direct-sale stands, and marketsHow to enjoy buying food near where it's produced, visiting and shopping at morning markets and fish markets, what to expect at farm stands, and finding local food at roadside stations (michi-no-eki).

Dishes in the same style
- AjiA blue-backed fish sold year-round, served raw, minced as tataki, or fried. Fish that settle in one fast-flowing strait rather than migrate firm up and fatten, and are pole-and-line caught there under premium regional brand names.
- BuriA 'shusseuo' whose name changes with size. Winter's fat-laden 'kanburi' is prized raw, teriyaki-glazed, or simmered with daikon — bays where it fattens before wintering, then is taken in set nets, are valued for both fat quality and yield.
Ingredients and dishes from this land
Known for it here
- Known for it here: Hokkaido, Otaru
Spawning shoals once ran so dense the coast turned white in what was called 'kuki' — the wealth they brought survives in the city's herring mansions.
Uses
- Daikon-zushiA fermented sushi from the Kaga region layering daikon radish with dried herring in rice koji. Said to have taken root once herring carried by the Kitamae trading ships reached ordinary tables, it now sits alongside kaburazushi as a New Year staple.
- Nishin-zushiA fermented Fukui sushi layering daikon radish with dried herring in rice koji — a dish telling the story of kelp and herring the Kitamae ships carried down the Sea of Japan coast, sharing its lineage with Ishikawa's daikonzushi.
- Tsuyu NishimeTsuto-dofu, tofu wrapped in straw for better keeping, simmers in dashi with dried herring, taro, and kelp, seasoned with soy sauce and sugar — a dish of Minamiaizu. It is served at weddings, funerals, and festivals as an accompaniment to sake, and is said to still be served at local events.
- Migaki Nishin no Kouji ZukeA dish from Tsugawa in Agamachi, where rehydrated dried herring is salted with daikon and napa cabbage, then finished with sweet amazake. Born of the inland wisdom for using herring carried in by kitamae-bune ships, it is said to have been served as a New Year treat.
