Note: True World, which supplies many US sushiya with fish from Tsujiki, offers a very useful seasonal guide to neta varieties. You can see it here.
The Basics (most important!)
- Neta = in terms of sushi, this means the topping, or the fish!
- Shari = the sushi rice, typically white rice seasoned with some combination of vinegar, sugar, and salt
- Nigiri = the sushi (neta+shari)
- Omakase = a term meaning "I'll leave it to you"; the format of a meal at most high-end sushi is omakase, where a chef chooses the meal for you
- Itamae = literally means "in front of the counter", sometimes refers to an assistant sushi chef as opposed the head chef/master (sometimes called "taisho")
- Maki = sushi in "rolled" form (the type most Americans like to eat)
- Gunkan = a sushi style where seaweed is wrapped around the rice and topped with the neta
- Sushiya or "sushi-yasan" = sushi shop - I sometimes use this for brevity, and it also makes me sound cooler
Ingredients/Seasonings
- Aburi = means "torched" or "seared"
- Akazu = red vinegar, made from sake lees
- Dashi = a cooking base (most commonly for soup), made typically from fish and seaweed
- Gari = pickled ginger, served as a palate cleanser between bites
- Gomezu = white rice vinegar, most commonly used with sushi rice
- Kanpyo = a type of Japanese squash, usually marinated and served as maki
- Konbu = edible kelp, often used as a base seasoning or for curing fish (as in "konbujime")
- Kurozu = black rice vinegar, not typically used as a seasoning with sushi
- Myoga = Japanese ginger, sometimes used as a garnish
- Otsumami/tsumami = small appetizers or snacks served at the beginning of a meal
- Nori = dried seaweed, used for wrapping maki or "gunkan"-style sushi
- Ponzu = a yuzu-based sauce typically served with sashimi
- Shio = salt
- Shoyu = soy sauce
- Sudachi = small green Japanese citrus, with a tart, acidic flavor
- Tare = a seasoned soy sauce used for topping or basting (sometimes used interchangeably with 'shoyu' or 'tsume')
- Tsume = a sweet soy-based sauce, usually used with eel or squid
- Yuzu = small yellow Japanese citrus, most closely resembling a cross between grapefruit and orange
- Zuke = refer to neta that have been marinated, usually in shoyu
Neta
To give some sort of format to the laundry list below, I've decided to segment fish by their type. Books like this one (written by Nagayama-san of Dai San Harumi) are incredibly useful as a reference for this. In practice, the universe of fishthat a sushiya might serve probably numbers in the hundreds, but the list below will probably cover 95% of what you might encounter at a typical sushi meal, over the seasons.
You'll also notice that this list doesn't include any members of the salmon/trout family. That's because these fish (with very few exceptions) aren't typically served in Japanese sushiya and thus more commonly go by their English names.
Lean white fish (shiromi)
- Engawa - the dorsal fin muscle of hirame or flounder
- Fugu - blowfish (don't worry, it's not poisonous)
- Hirame - fluke
- Isaki - grunt
- Karei - flounder, of which various varieties might appears in different seasons (ex:mako-karei, same-karei)
- Kawahagi - trigger fish, often served with a dipping sauce made from its liver (kimo) and ponzu
- Kochi - flathead
- Kurodai - black snapper
- Madai - red snapper (sometimes used interchangeably with tai, but it's a different fish)
- Suzuki - sea bass
- Tai - sea bream
Medium-bodied white fish

Red-fleshed fish
- Katsuo - bonito, in season during autumn and winter
