Rice dishes ── Sushi
Oshi-zushi
sushi shaped by pressing rice and topping together in a mold
Sushi shaped by packing vinegared rice and toppings into a wooden mold and pressing under weight before slicing. Said to predate nigiri, it survives regionally in forms like Osaka's hako-zushi.
Lineage
What it's made of
Vinegared rice is packed into a mold — wood or bamboo bark, depending on the region — topped with cured mackerel, small sea bream, or fish floss, covered, and pressed under weight. Rather than shaping each piece by hand like nigiri, a whole block is pressed at once and cut into squares or rectangles, giving it a regular, uniform shape.
How it's made
The inside of the mold is dampened with vinegar so the rice won't stick, then rice and toppings are packed in alternating layers. A lid and weight press it for anywhere from tens of minutes to several hours. Once unmolded, it's sliced with a wetted knife. How long it's pressed is said to shape both how well the flavors meld and how firm the texture turns out.
Why it took this shape
Curing fish in salt or vinegar rather than serving it raw, then packing and pressing it in a mold, is said to have been practiced mainly around the Kansai region even before nigiri spread as street food. Being preparable in bulk and easy to transport is thought to have suited it to festivals and celebrations needing to feed many people at once, and it survives today across the country with the mold's size and toppings changing by region.

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
- Nigiri-zushiVinegared rice topped with a slice of fish or other seafood and lightly pressed into shape. So central to sushi today that the word 'sushi' often means this alone, it's said to have spread as late-Edo street food.
- NarezushiFish salted and packed with rice for a long lactic fermentation — thought to be the oldest form sushi took. Some eat the rice too, others discard it and eat only the fish, sharply sour and pungent either way.
- HinezushiSalted fish is packed into a tub with rice, chili, and sansho leaves and left to ferment for a month or two — a narezushi from the Oku-Noto area whose flavor is said to shift with the salt level and the weather, varying even when the same person prepares it each time.
Derived style
- Hako-zushiOsaka's sushi pressed in a wooden box and cut into neat pieces — a form older than nigiri.
- Iwakuni-zushiA pressed sushi from Iwakuni, layered three to five tiers deep in a wooden frame. Lotus root, shiitake, and shredded egg stack into a striped cross-section — a dish also known as 'the lord's sushi,' cut and shared at celebrations.
- Kakinoha-zushiThin-sliced salt-cured mackerel over vinegared rice, wrapped tight in a bitter persimmon leaf and left overnight — a pressed sushi from Yoshino, Nara, where the leaf's tannin is said to do double duty as preservative and flavoring.
- Kokera-zushiA pressed sushi from the Higashi-Kishu coast of Mie, stacking an odd number of toppings — cured mackerel, dried shiitake, and more — three or four tiers deep in a wooden mold. Named, it's said, for the way the layers shingle like a cedar-bark roof.
- SakezushiA Kagoshima pressed sushi built on rice splashed with a local ash-cleared sake, layered with about ten toppings like sea bream and shrimp and left to ferment half a day. Local telling traces it to leftovers from a flower-viewing feast.
- Suko-zushiNon-glutinous and glutinous rice cooked together and topped with Ariake Sea and hill-country ingredients like grilled mudskipper, pressed square in a wooden box called a morobuta — a hospitality dish from Shiroishi, Saga.
- Omura-zushiWhite fish crumble, dried gourd shavings, and shredded egg layered and pressed in a wooden frame — a sushi from Omura, Nagasaki, said to trace to troops fed after retaking their castle. Its rice carries a gentle sweetness.
- Boze no Sugata-zushiA whole butterfish, locally called boze, butterflied and wrapped around vinegared rice to keep its shape intact — an autumn festival sushi from Tokushima, best made with the freshest, firmest fish.
- Bo-zushiVinegar-cured fish laid over rice and rolled bar-shaped with a bamboo mat before slicing — a form of pressed sushi seen in Kyoto's saba-zushi and regional saury and mackerel versions elsewhere.
