Before explaining "how Japanese people develop environmental awareness", I want to introduce the most basic and important common sense of Japanese society, that is, "Don't disturb others".

Japanese people have been deeply instilled with this basic common sense of "don't disturb others" since childhood.

"Being late for work", "making mistakes at work", "not keeping appointments for no reason" and "littering" and so on, all behaviors that do not follow social rules, no matter how big or small, will be despised by society, rejected by the collective and condemned by public opinion.

The Japanese have a strong sense of collectivity, and being despised and rejected by the collective (companies, departments, neighbors, classmates and colleagues) is the most embarrassing and disturbing thing for the Japanese.

So the Japanese learned the common sense of "garbage sorting" from their parents at an early age. In addition, many service agencies and commercial organizations in Japan will also post notices to remind customers of "smoking area" and "non-smoking area". Some packages will be printed with "combustible", "nonflammable", "recyclable", "non-recyclable" and "disposal method".

In addition, Japanese city prisons have printed pamphlets on environmental protection and distributed them to urban residents (including foreigners) free of charge.

And it has been translated into many foreign languages, telling foreigners how to sort garbage, throw garbage, donate reusable items and collect reusable items in Japan. And the contact information of some hazardous waste recycling institutions.
