From long ago Japanese thought, that the time is certain cycle, where the seasons are changed each other. First season is spring, which means the changes in nature and beginning some new in the people life.
Spring gauze is appeared in an air, the trees are blossomed, here and there could hear a nightingale. A lot of work in the gardens: feed up the trees, cut the dead limb, put a prop under the crooked trunks, create some sea and mountains landscapes from the gravel and sand by landscape rake. The Japanese formed this reverential attitude to the nature because feel themselves the organic part of it sensitively.
By the way the school child begin their new school year and all companies – new financial year.
