The climate of japan is modified by insularity and also by meeting of the cold and warm ocean currents. It receives adequate rainfall from both the south east monsoon in summer and the north west monsoon in winter.
During the north west monsoon dry cold wind from mainland Asia blows. But they gather moisture on its way from sea of japan to give heavy relief rain or snow on the western coasts of Japan.
The rainfall is more evenly distributed, as in Tokyo, with two maxima, one in June, the Plum rain and the other in September the typhoon rain. The Warm Kuroshio has played an important role in making the climate of Japan less extreme. In meeting the cold Oyashio from the north, it also produces fog and mist, making North japan a second new foundland. Fishing replaces agriculture as the main occupation in many of the indented coastlands.
