History of the bento box

In Japan, the tradition of compartmentalizing food in a box in order to easily have a meal outdoors does not date from yesterday, but from the 12th century. Originally, the bento box was filled with rice and dried fish which was later replaced by rice balls with vinegar (onigiri). Nowadays, Japanese bento boxes can consist of all kinds of foods, according to your taste and desire.

During the Edo period, this meal box was related to special events such as hanami (picnic under cherry blossoms) or hina matsuri (girls' day). In traditional Japanese theater, known as kabuki in Japanese, the makunouchi bento was eaten during the intermissions when the curtain (maku) was lowered.

Traditionally, bento boxes include take-away meals, prepared at home. Nowadays, it is possible to buy ready-made bento in konbini, supermarkets, some restaurants and even in train stations, where the bento is known as eki-ben.

How to choose your bento?

The size of the box may surprise you at first, especially those who tend to have eyes bigger than their stomach, but the bento box has the advantage of being adapted to your (real) food needs of the day and being easily transportable at the same time.

To choose the right bento box, the gender and age of the person should be taken into account. Thus, for a woman between 18 and 60 years old, a suitable bento box will have a capacity of 700 ml. For men between 18 and 60 years old, a 900 ml capacity bento box is ideal. There also exists many boxes with larger capacities for those who are afraid of not having enough to eat or for those who want to take an extra snack for the 10 am or 4 pm hunger. In this case, a bento box with a 1400 ml capacity will be perfect.

You can choose your bento with one, two or three layers. The advantage of the multi-tiered bento is that you can separate them, so that you can microwave only one compartment - your main dish - while enjoying your fresh salad in the second compartment. Nowadays, you can either choose from the traditional wooden bento or a more modern version in plastic and rice straw, but you can also select among different shapes: oval, square, rectangular, high or flat.

How to compose your bento?

In Japan, the bento is not only a meal box, but also an art. Food must be arranged in a harmonious way, both in terms of taste and visual appearance.

Traditionally, the bento is prepared early in the morning by Japanese mothers for the lunches of her children and her husband. Mothers are very creative in preparing kawaii bento that will make their kids feel like eating all kinds of food, even the vegetables. For this, the food is shaped and cut to look like Japanese cartoon characters, landscapes or animals. These bento are called kyaraben and are a great opportunity for stay-at-home moms to compete with each other and see who can create the most beautiful and colorful bento for their children.

A bento box is primarily designed to provide a complete and balanced meal. Therefore, the different compartments of the bento box allow to compose a lunch according to the following proportions: 

  • 40% rice or other starchy food
  • 30% protein, found in meat or fish
  • 20% vegetables
  • 10% fruit for dessert

Three reasons to adopt a bento box
