Chatokun, actually the pic that Altariel mention looks like real crab to me and nothing like Kamaboko. Notice how it's uneven and how two pieces of meat (from thinner leg) were used to make the upper (right) one. Kamaboko has a very consistent look and texture.
Nice use of sushi key words to make yourself sound smart though.
Actually, real crab looks more like the pic here. Though, this is maki(rolled) sushi whereas the game uses mostly nigiri(squeezed) sushi. The pic you have may be real, but most fake crab actually looks more like that, and is made similar to kamaboko.
From http://en.wikipedia.org/wiki/Kamaboko
"The simulated crab meat product kanikama (short for kani-kamaboko), the best known form of surimi in the West, is a type of kamaboko."
