There are many warm and positive messages displayed in Japan. Like this one: "Nature is our teacher." It may seem simple, though it comprises a deep meaning and profound respect for nature, indeed. It is a country that thoroughly beautifies it and keeps it clean.
One Japanese proverb says: かちょうふうげつ ka-chou-fuu-getsu 花鳥風月. These are the beauties of nature: flower-bird-wind-moon. Nature is our mirror; being closer to nature we learn more about ourselves.
