Monthly Weather of Japan - Temperature & Rainfall
Typhoon Season in Japan
In East Asia, Japan sees its typhoon season from June to October generally, with September to early October being the peak months. The entire Japan would encounter 20-30 typhoons every year, which bring plenty of rain and gale to the landing areas.
The rainy season will last for one month or one and a half months in Japan, generally from May to July. Rainy season begins in southern islands of Japan in early May or mid-May; the farther north you go, the later the rainy season comes. To the northeast of Honshu, rainy season comes in the early or middle June. As for Hokkaido, it is relatively an exception in Japan with no rainy season.
Cherry blossoms are blooming in the southern regions first. The farther south, the earlier the cherry blossom season. In the south of Kyushu, cherry trees put forth the blossoms in late March; to south of Hokkaido and the northernmost of Honshu, it begins until late April.
