I don't think I have ever met anyone that hates sushi. It's like that one food that everybody collectively agrees is good.
A Brief History
Sushi apparently originated as something called narezushi near southeast Asia, where fish was fermented, to help preserve food. It made its way to Japan, where, over time, rice vinegar was discovered and rice was boiled instead of steamed. Then this guy called Hanaya Yohei decided to one day put raw fish on the rice, inventing the modern tokyo-style sushi (edomaezushi, 江戸前寿司) which we eat today.
So, Salmon?
If you have had sushi in Japan, or have gone to expensive sushi restaurants with authentic chefs and ingredients, you would have probably noticed that there is rarely any salmon at all, even though it's the most used fish in sushi.
The reason is, because a long long time ago, like before the 80s, salmon in Japan was never served raw, due to parasites. But then these Norwegians came along and, to get rid of their large amounts of farmed uneaten salmon, introduced it to the Japanese.
Sooner or later, salmon became a staple in "japanese" cuisine all around the world, and it really feels like it. I know I'm basic, but salmon is just chef's kiss so damn creamy and good.
Types of Sushi
So I think everybody has encountered either the nigiri or the maki roll.
The nigiri (nigirizushi, にぎり寿司), is like the classic original sushi. One nice piece of raw fish slapped onto a chunk of rice.
The maki, or maki roll (makizushi, 巻き寿司), is one of those rolls of fish, (or cucumber, or just any topping) with rice around it wrapped around a sheet of nori (海苔), and it's usually the stuff that's easier to make, and comes in like 6s, and cheaper as well. These are great for a small meal or snack. The fake crab leg ones are kind of underrated in my opinion.
Some others you may not have heard of include:
The temaki, or hand roll (temakizushi, 手巻き寿司) is sushi that you hold like an ice-cream cone. This makes it a lot more easier to eat apparently, but in my experience, it's pretty hard to get all the ingredients in one bite, and then you're just left with seaweed and rice at the bottom.
The uramaki (裏巻き) is an inverted maki roll, with rice on the outside. It is usually then covered in either sesame seeds or tobiko (とびこ), small red flying fish roe caviar. From what I've seen this is usually for larger rolls like the californian roll or the dragon roll.
The inari (inarizushi, いなり寿司) is a lot more different than your typical sushi. It's sushi rice covered in a fried tofu skin. The sushi is also slightly sweet, but I can't speak from experience because I have never tried it. Seems tasty tho.
The temari (temarizushi, 手まり寿司), meaning handball, is a type of sushi that is shaped in a (take a guess). I first learnt about this from Food Wars, where Alice was making a temari bento. Temari is also typically more decorated and fancy than other types of sushi.
The chirashi (ちらし寿司) is basically just a sushi bowl. It is often served during special occasions, and the toppings differ depending on the region, like lotus roots and shrimps.
