What does the Japanese word bento mean?

The term bento was borrowed from a Southern Song Dynasty Chinese slang term (biàndāng), meaning “useful thing” or “convenient thing”. This has a dual meaning since it refers to both the container and the content.

The modern word ‘bento’ is thought to have originated with Oda Nobunaga (1534-82), a sixteenth-century military leader who fed the vast crowds at his castle by having food given out to each person. To characterise the modest meals that were given in this way, the term bento was born.

The English translation of bento is “lunch box,” yet that hardly begins to convey the extreme importance in the imagination and reality of the experience of consuming what is inside. Bento’s are the quintessential essence of Japan encapsulated in a box. 

The History of the Bento Box

At its simplest, a Bento box is a Japanese to-go box containing a complete meal, most often for lunch. The original bento stretches back to the 5th century when bamboo boxes were used to send food to the fields, hunting grounds, or battlefields.

Workers began bringing tiny bags of cooked rice to work in the 12th century during the Kamakura Period. Later on, people began to utilise wooden boxes for gatherings. Onigiri, rice balls, became a common lunch in bento boxes by the 17th century as the technique of making them grew in popularity. Many students carried commercial bento boxes to school in the late 19th century when they were available.

Traditional Japanese cuisine is typically presented separately on several tiny plates. This method of little servings is also be seen within a Japanese bento box. Where each ingredient is neatly placed within each compartment, carefully planned out so that the foods do not mix. Making Bento Boxes easy to carry and ready to eat!
