 Weather in Japan

Due to its wide range of latitude, Japan hosts contrasting climate regions, ranging from a humid continental climate in the north to a humid subtropical climate in the south. The island nation has four distinct seasons, but the weather conditions differ between the Pacific side and the Sea of Japan side.
In Japan, the majority of rain falls during the rainy season, which usually lasts from early June to mid-July. Furthermore, heavy rain is often caused by typhoons, which regularly approach the archipelago between July and October.

 Climate change and extreme weather

Global warming has already influenced Japan's climate in recent years, resulting in increased average annual rainfall as well as an increase in the average annual temperature in Tokyo. These weather changes can intensify extreme weather situations and natural disasters such as heavy rain, typhoons, and heatwaves. In recent years, the higher frequency of heat waves with temperatures above 35 degrees caused health problems for citizens, as shown in the increase in the number of patients taken to the hospital with heat strokes.
