Were the lunchboxes that the students ate in Japanese comics hot?

Answer 1

Usually, the lunchboxes that students ate in Japanese comics were hot. In the anime culture, hot food had become a common food culture, and many anime characters were used to eating hot food at noon. This was because hot rice could provide better taste and nutrition and was more attractive than cold rice. In addition, anime works often depicted the protagonist living in a fast-paced modern society. Eating cold food might seem too bland, so hot food was more in line with the eating habits of the real world.
