As the "cleanest" countries, how do Japan and Switzerland maintain the environment on a daily basis?

Japan and Switzerland are recognized as the "cleanest" countries. Because Japan sits or kneels directly on the ground, they pay great attention to the hygiene of the ground. There are all kinds of shoe covers and special shoes. The tap water in Japan is well filtered and can be drunk directly. Garbage classification is very strict.

As long as you look at the dazzling array of shower gels, lotions and antiperspirants in supermarkets and shopping malls in Japan, you can know that Japanese people attach importance to personal hygiene, sometimes even to the point of cleanliness. Most people take a bath twice every morning and evening, and the clothes they wear today will never be the same as yesterday. When going to a hotel for business or tourism, you should take a bath, soak in a hot spring and change clothes immediately, and then do other things. Moreover, this kind of love for cleanliness is not unique to women. Japanese men attach great importance to appearance and body odor, so in Japanese shops, there are not only women's skin care products and cosmetics, but also men's skin care products, breath fresheners and masks, all of which are classified in detail.

Because of the habit of sitting on the floor, the Japanese pay great attention to the hygiene under their feet, and ordinary families have to take off their shoes before they can enter the door. The same is true of schools. There are special shoe cabinets at the entrance of Japanese primary and junior high school teaching buildings. Students should put on appropriate shoes or bring shoe covers before entering the teaching building. Some schools also require students to wear uniform soft-soled shoes. Before going to physical education class, students should put on sports shoes, which can not only prevent injuries, but also keep the ground clean.

As early as the Shanghai World Expo in China, the Japanese Pavilion once displayed tap water that can be directly drunk as the pride of its own country. Direct drinking water pipes for people to quench their thirst can be seen everywhere in the streets of Japan, and ordinary Japanese can basically drink water directly from the tap water hall at home. If nothing else, the water purification technology of Japanese waterworks is very high. Ordinary water and even sewage have reached the level of direct drinking after multi-layer filtration and advanced treatment with activated carbon, ozone and biology. People don't have to worry about cutting corners in the water plant, because once found, the fine is enough to stop the factory.
