Vegetarian sushi can be saved for the next day since it does not contain fresh fish.
It is not always a good idea to do that it depends a bit on how careful you have been with the preparation of materials such as the rice.
By that I mean that if the rice is not cooked to perfection and kept in the right way the individual rice grains will get tougher and they will also looser their texture.
The vegetables should be prepared or cooked to perfection, otherwise any moisture will get sucked into the rolls and it will give a cloth-like feel.
