As for cold rice, Japanese cold food is also a habit (raw fish, rice balls and many others are cold food), and the Japanese diet "rice" is rice. Rice, the food is a little cold, and the children's spleen and stomach are cool (you will find it when you grow up and eat cold drinks). . ）。 When I go to work, the lunches bought by ordinary convenience stores will be heated by microwave, and some companies also have microwave ovens to heat them.
Primary schools in Japan provide lunch, but it is not free, and you have to pay monthly. Tuition is free. Some middle schools provide lunch; Some do not provide, must bring lunch; There are also canteens, which can be eaten or brought by yourself. Schools are different. All high schools do not provide lunch, so you must bring your own or eat in the canteen.
Why do middle schools and high schools bring their own lunches instead of providing lunch? Because of financial problems.
The school canteen can't make a profit, but only charges for materials, and the gap is filled by the local government. Therefore, maintaining the canteen requires a lot of money every year, which is the direct reason.
In addition, Japanese society also has the family conditions to bring lunch to children-mothers are mostly full-time housewives. They also have the conditions of food culture-they are used to eating cold food, unlike what China thought should be hot. There is no collective hot lunch box in Japan like China, no matter where the company is or where it is, it is a microwave oven.
