In this paper the author summarized the researches done in Japan on the relation between sunspots and meteorological phenomena.<BR>The idea common to almost all the researchers is that the sunspots as an index of solar activity cause the variations of atmospheric pressure on the earth namely, as the conditions of the earth's atmosphere which receives solar radiation are varying according to seasons and locations, the changes in solar radiation due to sunspots cause the variations of the distribution of atmospheric pressure, which result in disturbances of air currents and in climatic variations. And these disturbances are almost strongly effected, in Japan, by the changes in the intensity of the North Pacific High and by the migration of its center.<BR>A few Japanese researchers are making use of the faculae instead of sunspots in their researches, and they consider the degree of the faculae's facing to the earch as the solar activity index, and this consideration seems to be an excellent one perhaps unseen in other countries.
