Hatahata-zushi
fermented sandfish sushi for a New Year that can't start without it
Sandfish landed only in the waters off Akita, packed in rice and rice koji to ferment about three weeks. The fish arrives in huge schools only during its short spawning run inshore, and the whole catch gets preserved this way.

Lineage
What it's made of
Sandfish are butterflied and gutted, given a preliminary cure of vinegar and salt, then layered with cooked rice, rice koji, and bamboo leaves. Carrot, funori seaweed, yuzu, and ginger add color and scent, and about three weeks of fermenting somewhere cool leaves the flesh a thin amber, carrying koji's sweetness alongside the vinegar's tang.
How it's made
Sandfish are gutted, rinsed in cold water, bled for about three days, then cured in vinegar. Rice mixed with koji is layered with bamboo leaves in alternating tiers, weighted, and left to ferment about three weeks somewhere cool. Some households finish it with a touch of sake and mirin for extra depth.
Why it took this shape
Sandfish live in deep water and come inshore in huge schools only in late autumn and early winter, timed to thunderstorms, right before spawning. A local saying holds the New Year can't arrive without it — a sign of how this fermented sushi grew out of the need to make a fish caught in one short burst last much longer. It's also a dish built on Akita's identity as rice country, using rice and koji without restraint.

- How to use a convenience storeA quick guide to choosing rice balls and hot snacks, buying coffee, paying by cash, IC card, or tap payment, using the eat-in corner, and sorting your trash — the basics for a first visit.
- 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.
Dishes in the same style
- Aburi-zushiNigiri with just its surface flash-seared by torch or hot iron. Unlike Edomae's shigoto curing for keeping, the searing here is done purely for the change in aroma and fat it brings — a relatively recent way of eating sushi.
- Aichi HakozushiVinegared rice is packed into a wooden frame, topped with shrimp, eel, shiitake, and egg arranged diagonally, and pressed. Placing toppings on the diagonal so everyone gets a fair share of each is said to be a feature of the Owari and western Mikawa style, made for celebrations.
Ingredients and dishes from this land
Contrast
- Akazushi (Akazuke)Cooked glutinous rice cured briefly in red shiso and vinegar — an Akita sushi with no fish in it at all, a plant-based cousin of narezushi also offered at Obon altars.
- Hatahata ZushiKnown locally as "shirohata zushi," this dish from Tottori City's Karo district cures sandfish in vinegar, then stuffs the belly with toasted, seasoned okara instead of rice. Being rice-free, it eats light, and it's been served as a feast dish at Karo Shrine's biennial Hoenya festival.
Also from Akita
- AsazukeBroken rice grains are pureed, simmered, and seasoned sweet-and-sour with sugar and vinegar, then mixed with cucumber, turnip, and seasonal fruit — a summer dessert unrelated to the pickle of the same name, said to refresh women after a day planting rice.
- Edokei RamenA soy ramen topped with a knob of bright red chili miso built on garlic and garlic chives. Stirred in gradually as you eat, it turns a mild bowl steadily richer and spicier — a specialty of Akita City.
- Akita HoshimochiSliced mochi is strung up, soaked in water, then left to freeze and thaw through the winter cold in a process called 'kanjime' — the result crisp and filling, said to have fueled breaks during rice-planting season.
- Imonoko JiruBaby taro corms called 'imonoko' simmer with chicken, mushrooms, and wild greens in miso or soy — an autumn soup said to use taro grown in Yokote's Sannai district, prized for its soft bite, and set alongside kiritanpo nabe as the region's autumn counterpart.
- Akita no SakeAkita sake, brewed with soft water in deliberate contrast to Nada's hard water, aiming for a mellow, delicate character. Breweries buried in snow are said to gain a natural insulating effect from it, a tradition of slow, low-temperature fermentation built around that climate.
