What’s in that sushi roll?

A field guide to 17 classic rolls. Match the cut face on your plate to a cross-section, see what’s inside and where it comes from, then roll your own.

A California roll, cut open. From the outside in: sesame seeds, rice, a sheet of nori, then crab stick, avocado and cucumber.

Five shapes of roll

Most rolls you’ll meet come in one of these shapes. The quickest tell is where the nori sits: outside the rice, inside it, or wrapped around it like a wall.

  • Hosomaki 細巻き

    The thin roll, 2.5 to 3 cm across: half a sheet of nori around rice and usually a single filling. Normally cut into six pieces.

    Spot it by its small size and single filling.

  • Futomaki 太巻き

    The thick roll, 5 cm or more across: a full sheet of nori around several colourful fillings.

    Spot it by the wide, crowded middle.

  • Uramaki 裏巻き

    The inside-out roll: rice on the outside, nori wrapped around the filling. The shape behind most Western-style rolls.

    Spot it by the missing nori on the outside.

  • Temaki 手巻き

    The hand roll: a cone of nori, filled and eaten by hand straight away, while the nori is still crisp.

    Spot it by the cone shape; it isn’t sliced.

  • Gunkanmaki 軍艦巻き

    The “battleship” roll: a strip of nori wrapped around a small oval of rice, rising above it to hold loose toppings such as salmon roe.

    Spot it by the topping piled above the nori wall.

Which roll is that?

Compare the cut face on your plate with these cross-sections, then pick one to read about it.

Classic Japanese rolls

Thin rolls with one filling, and the thick futomaki. Simple combinations that let the rice, the nori and a single ingredient speak.

Kappa maki かっぱ巻き

  • Thin roll
  • Vegetarian

Crisp cucumber in rice and nori: the plainest roll on the menu, and one of the most refreshing.

Inside
Cucumber, sometimes with a few sesame seeds.
Spot it by
A small roll with a pale green centre and a dark green edge of cucumber skin.
Name
After the kappa, a water creature of Japanese folklore said to love cucumbers. At sushi bars, cucumber itself is nicknamed kappa.
Origin
A 20th-century roll. Sushi shops in Osaka and in Tokyo’s Waseda district both claim to have created it.

Tekka maki 鉄火巻き

  • Thin roll
  • Raw fish

A stick of lean red tuna (akami) rolled in rice and nori. Simple, and only as good as the tuna.

Inside
Raw lean tuna.
Spot it by
A deep red square of tuna in the middle of a small roll.
Name
Tekka means “red-hot iron”. One popular story links the roll to gambling dens (tekkaba), where it made a quick meal eaten by hand; another to the tuna’s fiery red. Neither is proven.

Negitoro maki ねぎとろ巻き

  • Thin roll
  • Raw fish

Soft, pink minced fatty tuna mixed with chopped green onion. Rich and melting rather than firm.

Inside
Minced fatty tuna (toro) and green onion (negi).
Spot it by
A soft pink filling flecked with green.
Name
Usually explained as negi (green onion) plus toro (fatty tuna). A popular alternative, from a supposed verb negitoru, “to scrape off”, is probably a folk etymology.
Origin
Usually credited to the Tokyo sushi shop Kintaro-zushi, around 1964, as a way to use tuna scraps.

Kanpyo maki かんぴょう巻き

  • Thin roll

Strips of dried gourd, simmered until tender in a sweet soy mixture. The original Tokyo roll: chewy, savoury-sweet, and traditionally cut into four pieces rather than six.

Inside
Simmered kanpyo: dried, shaved strips of bottle gourd.
Spot it by
Glossy light-brown ribbons in the middle.
Also called
Teppo-maki, “gun-barrel roll”, and in Tokyo simply norimaki.
Vegetarian?
Often, but not always: some cooks simmer the gourd in dashi made with fish.

Oshinko maki お新香巻き

  • Thin roll
  • Vegetarian

A bright yellow stick of pickled daikon radish (takuan). Crunchy, salty-sweet, and a good palate cleanser.

Inside
Takuan (pickled daikon), occasionally other pickles.
Spot it by
A vivid yellow square in the middle.
Also called
Takuan maki or shinko maki. Oshinko simply means pickles.
Vegetarian?
Usually. A few brands of takuan contain bonito extract.

Natto maki 納豆巻き

  • Thin roll

Fermented soybeans, sticky and pungent, often with chopped green onion. Loved and avoided in equal measure.

Inside
Natto (fermented soybeans), often with green onion.
Spot it by
Brown beans in a stringy, sticky filling.
Vegetarian?
The beans are, but natto is often seasoned with a sauce containing bonito, a fish. Ask if it matters to you.

Futomaki 太巻き

  • Thick roll

A thick roll, 5 cm or more across, packed with cooked and seasoned fillings and sliced into thick rounds. At Setsubun in early February, many people in Japan eat one whole and uncut, as an ehomaki.

Inside
In Tokyo style: rolled omelette (tamagoyaki), simmered kanpyo and shiitake, spinach, mitsuba or cucumber, and sweet pink fish flakes (sakura denbu).
Spot it by
A wide roll with a crowded, colourful middle: yellow, brown, green and pink.
Ehomaki
Eaten whole, in silence, facing the year’s lucky direction. The custom comes from the Osaka area; Seven-Eleven began selling it across Japan in 1998, and the name ehomaki spread with it.
Vegetarian?
No: the pink flakes are made from fish.

Western-style rolls

Mostly created in North American sushi bars: usually inside-out, often with avocado, mayonnaise, fried fillings or sweet sauces. Inside-out rolls are still rare in Japan itself.

California roll

  • Inside-out

The best-known inside-out roll: imitation crab, avocado and cucumber, with the rice on the outside. The earliest versions used real crab.

Inside
Imitation crab (kanikama, a cooked fish paste) or real crab, avocado and cucumber. The crab is often mixed with mayonnaise.
Outside
Rice coated with sesame seeds or orange fish roe (tobiko or masago). The roe isn’t cooked.
Spot it by
Rice outside; a white-and-red crab stick and a pale green crescent of avocado in the cut face.
Origin
Disputed. Most often credited to Ichiro Mashita at the Tokyo Kaikan restaurant in Los Angeles in the 1960s. A 1979 news report credited Ken Seusa of Kin Jo, also in Los Angeles, and Vancouver chef Hidekazu Tojo says he made an inside-out version in the 1970s.

Philadelphia roll

  • Inside-out
  • Smoked fish

Smoked salmon and cream cheese, the pairing from a bagel with lox, rolled inside-out with cucumber. Smoked salmon is cured, not cooked.

Inside
Smoked salmon, cream cheese and cucumber. Avocado, green onion or sesame are common extras, and some places use raw salmon.
Spot it by
Bright orange salmon above a white block of cream cheese.
Origin
Philadelphia chef Madame Saito says she created it in the 1980s, though her accounts vary. Whether the name refers to the city or the cream cheese brand is unclear.

Spicy tuna roll

  • Inside-out
  • Raw fish

Chopped raw tuna mixed with mayonnaise and chilli sauce. Creamy, with a gentle heat.

Inside
Raw tuna in spicy mayonnaise (in the US usually made with sriracha), often with cucumber or green onion.

Dragon roll

  • Inside-out, topped

An inside-out roll draped with thin slices of avocado that overlap like scales, finished with sweet, dark eel sauce.

A deep-fried soft-shell crab, shell and all, rolled so its crispy legs poke out of the end pieces. That’s where the name comes from. Rarely seen in Japan.

Inside
Fried soft-shell crab, cucumber and avocado; often daikon sprouts or lettuce, and spicy mayonnaise.

Often fish roe (tobiko), which isn’t cooked.
Spot it by
Crispy crab legs sticking out of the ends.

A short history of the roll

From pressed seaweed in Edo to convenience-store rolls. Where the records disagree, the entry says so.

  1. Edo period

    Makers in Edo, today’s Tokyo, start pressing seaweed into thin sheets on frames, borrowing the method of local papermakers. Accounts date it anywhere from the late 1600s to the 1770s. Sold as Asakusa nori, it is the ancestor of every sheet used today.

  2. 1750

    The word makizushi first appears in print, in Ryori Sankaikyo, a cookbook published in Kyoto. Its roll is not the rice-and-nori kind: it is cured fish rolled up with grated daikon.

  3. 1776

    A cookbook describes rice and fish laid on a bamboo blind lined with nori and rolled up: the first recognisable sushi roll in print.

  4. 1837–53

    Morisada Manko, a record of everyday life, notes that in Edo rolls are called norimaki and hold nothing but kanpyo.

  5. 1940s

    Kyubey, a sushi restaurant in Ginza, says its founder created the gunkanmaki, a nori wall around rice, to hold soft sea urchin.

  6. 1960s–70s

    Inside-out rolls appear in North America. Los Angeles and Vancouver both claim the first California roll.

  7. 1972

    Sugiyo, a fish-cake maker in Ishikawa Prefecture, launches the first crab-flavoured kamaboko, forerunner of the imitation crab in today’s California rolls.

  8. 1980s

    The spicy tuna roll and the Philadelphia roll join American sushi menus.

  9. 1998

    Seven-Eleven sells ehomaki for Setsubun in its stores across Japan, turning an Osaka custom into a national one.

Roll your own

You need a bamboo rolling mat, a sharp knife, nori and well-seasoned rice. Start with thin rolls: one filling, half a sheet of nori, and very little that can go wrong.

Sushi rice

For 300 g of uncooked rice (2 Japanese rice-cooker cups)

  • 300 gJapanese-style rice: short-grain, or medium-grain Calrose (about 1½ US cups)
  • 360 mlwater, or fill a rice cooker to its sushi line
  • 4 tbsp (60 ml)rice vinegar
  • 2 tbsp (25 g)sugar
  • 1 tspsalt
  1. Rinse the rice until the water runs almost clear, then drain. If you have time, let it soak for 20 to 30 minutes.
  2. Cook it with the water, then let it stand, covered, for 10 minutes.
  3. Stir the sugar and salt into the vinegar until they dissolve.
  4. Tip the hot rice into a wide, damp wooden tub or bowl. Pour over the seasoning and fold it in with a paddle, using slicing strokes rather than stirring.
  5. Fan it, or just leave it, until it cools to about body temperature. Keep it under a damp cloth and use it within a few hours; the fridge makes it hard.

Recipes vary. The vinegar maker Mizkan uses 3 tbsp of vinegar for the same amount of rice, and some cooks add more sugar. Taste and adjust.

A thin roll, step by step

Six pieces of kappa maki or tekka maki from one half sheet of nori.

  1. Set up

    Lay the bamboo mat flat, slats running across, and put half a sheet of nori on it, shiny side down. Keep a bowl of water with a splash of vinegar nearby for your hands.

  2. Spread the rice

    With damp hands, spread a thin, even layer of rice over the nori, leaving a finger-wide strip bare along the far edge. Press lightly; packed rice turns heavy.

  3. Add the filling

    Lay a single line of filling across the middle of the rice: a cucumber stick, a strip of tuna, a stick of pickled daikon.

  4. Roll

    Lift the near edge of the mat and roll it over the filling until the nori meets the rice on the far side. Squeeze gently along the length, then roll forward to seal the bare strip.

  5. Slice

    Wipe a sharp knife with a damp cloth. Cut the roll in half, then each half into three, wiping the blade between cuts.

Bare strip Thin rice Filling Start rolling from this edge
Half a sheet of nori on the mat, seen from above: rice spread thinly, a bare strip along the far edge, and one line of filling across the middle.

Inside-out rolls

Cover the mat with cling film. Spread rice over a whole half sheet of nori and sprinkle it with sesame seeds, then flip the sheet so the nori faces up. Add the filling, roll as above, and cut into eight.

Raw fish at home

Buy fish sold for eating raw. Freezing kills parasites, though not bacteria: EU rules require −20 °C for at least 24 hours or −35 °C for 15 hours, and US FDA guidance −20 °C for 7 days. A home freezer usually runs at about −18 °C. The FDA advises pregnant women, young children, older adults and anyone with a weakened immune system to avoid raw fish. Eat sushi the day you make it, and don’t leave it out for more than two hours.

At the counter

A few customs worth knowing. None of them should stop you enjoying your food.

  • Hands are fine.Eating sushi with your fingers is perfectly acceptable, even at a formal counter. Chopsticks work too.
  • Dip lightly.Rice soaks up soy sauce quickly. With nigiri, dip the fish side, not the rice. If the chef has already brushed a piece with sauce, eat it as it comes.
  • Go easy on mixing wasabi into soy sauce.Many sushi chefs season each piece themselves and would rather you didn’t. At casual places it comes down to taste.
  • Ginger goes between pieces.Pickled ginger (gari) is there to refresh your palate between different fish, not to be piled on top.
  • Eat hand rolls right away.A temaki is best eaten the moment it’s handed to you, while the nori is still crisp.
