But many times, the shop assistants of the whole family put the whole lunch box into the microwave oven to heat it, that is, put the lid and the plastic wrap outside into the microwave oven to heat it. Yes, the box is fine, but the lid and the transparent plastic wrap outside are not. Moreover, many bentos are marked with the lid made of different materials from the box, and the lid should be removed before heating. However, I have never seen a shop assistant open the box and put it in the microwave oven to heat it. So, from now on, I won't buy lunch for the whole family.

Japan's unique bento culture

The reason why bento is deeply loved by Japanese people is closely related to its dietary characteristics. Japanese people's eating habits are mainly rice with side dishes. Rice is made from Japanese rice. The rice grains are short and round, and the taste is still delicious after cooling. Most Asian countries outside Japan eat long, thin and flat Indian rice, and the taste after cooling is not as good as Japanese rice. The so-called bento is a kind of meal with side dishes and pickles on the cold rice and packed in a portable container when going out.

Japan is an economically developed country, but it still has the habit of taking meals to work and school, because box lunch is a representative of Japanese food culture. Although many kindergartens and schools have started to provide lunch for students, many children still take lunch to school. Especially in sports games or travel, children need to bring their own meals. Japanese people are very particular about making lunch, and usually cook the dishes and meals of the day in the morning. If it is for children, they will also make vegetables and rice into some animal or plant shapes to make children happy.
