What's the climate like in Japan in April?

Spring in Japan generally starts around February 10 and ends in mid-May, with changeable weather and less rain. Summer lasts six months, seven months and eight months. Due to the control of the Pacific subtropical high, the southeast monsoon with high temperature and high humidity affects Japan. There is a long period of sultry weather in the south of Honshu, and the precipitation on the Pacific side, that is, "Japan", is relatively large. The important feature of summer in Japan is that the rainy season appears shortly after summer and lasts for a long time. September, 10, 1 1 is autumn in Japan. Autumn is crisp, as the saying goes, "autumn is crisp, and horses are fat." From the beginning of September to the beginning of 10, there is another autumn frost season in Japan, during which typhoons are frequent and often accompanied by heavy rains, causing harm. Winter in Japan generally lasts from 165438+1October 20th to February 20th of the following year. Affected by the cold northwest monsoon from the Asian continent and the warm current on horses along the coast of the Sea of Japan, there are many snowfalls, cloudy days, short sunshine and humid air on the side of the Sea of Japan, while there is little rain, sunny and dry on the side of Japan. In winter, the temperature difference between north and south of Japan is quite large. For example, the monthly average temperature in Asahikawa, Hokkaido is -7.8℃ at 65438+ 10, and that in Naha, Okinawa 17.2℃, with a difference of 25℃. Due to the rainy season and autumn frost period, Japan also has the saying that there are six seasons in a year.
