They think sleeping on solid ground is better for the waist. But Japan doesn't sleep directly on the ground. On this basis, they will weave a mat with straw mats, which are collectively called "tatami" in China. Many people in China will prepare several such mats at home for easy use.

Another reason is that Japan's land area is very small, so sleeping directly on the ground is more space-saving and very simple than a bed. So in countries like Japan, in order to save space, they choose to sleep directly on the ground.

Eating habits in Japan

Japan's diet is very delicate, with fish, meat, vegetables, beans, fruits and rice noodles, all of which are served in small dishes and bowls with various patterns. In this way, although you don't eat much at each meal, you can ensure a variety of nutrients.

They eat vegetables for three meals a day, and bread with salad, rice and vegetables to ensure the absorption of cellulose and vitamins. Japanese eat milk and dairy products every day, and women are twice as many as men. Milk and yogurt are rich in protein, calcium, vitamin A and vitamin B.

Japanese people pay great attention to the amount of salt, and often use vinegar, mustard, pepper, spices and other appropriate seasonings instead of salt, which not only enriches the taste of dishes, but also does not consume too much salt.
