First of all, to correct you, Japanese sushi is not called "big roll" or "small roll", but "thick roll" and "thin roll". Japanese is called:

Put laver rice and side dishes on the bamboo curtain of sushi, roll them into thick rolls and cut them into sections.

Fine (まきほそまき) Put the laver rice and side dishes on the sushi bamboo curtain, roll them into fine rolls and cut them into sections.

Roll 1/2 pieces of laver, rice and side dishes into a sharp barrel shape by hand.

This warship 怗き (ぐんかんまき) holds a rice ball that can be eaten in one bite, puts it on the chopping board, encloses the rice ball with slender laver slices, the height is slightly higher than the height of the rice ball, and then serves side dishes (roe) on it.
