Sushi bento boxes are a staple of Japanese supermarkets and convenience stores. As these stores began rising in prominence in the 1960s, the labor-intensive cut leaves were increasingly replaced with green plastic to lower costs. This coincided with the increased prevalence of refrigeration, which extended sushi's shelf life without the need for cut leaves. Today plastic strips are commonly used in sushi bento boxes and, to a lesser degree, in sushi presentations found in sushi bars and restaurants. In store-sold or to-go packages of sushi, the plastic leaf strips are often used to prevent the rolls from coming into early or unwanted contact with the ginger and wasabi included with the dish.

Etiquette
Unlike sashimi, which is almost always eaten with chopsticks, is traditionally eaten with the fingers, even in formal settings. Although it is commonly served on a small platter with a side dish for dipping, sushi can also be served in a bento

, a box with small compartments that hold the various dishes of the meal.
Soy sauce is the usual condiment, and sushi is normally served with a small sauce dish or a compartment in the bento. Traditional etiquette suggests that the sushi is turned over so that only the topping is dipped to flavor it; the rice—which has already been seasoned with rice wine vinegar, sugar, salt, mirin, and kombu—would otherwise absorb too much soy sauce and would fall apart.
Traditionally, the sushi chef will add an appropriate amount of wasabi to the sushi while preparing it, and the diner should not add more.[ However, today, wasabi is more a matter of personal taste, and even restaurants in Japan may serve wasabi on the side for customers to use at their discretion, even when there is wasabi already in the dish.]
