シベリア高気圧
The climate is colder than in other parts of Honshū due to the stronger effect of the Siberian High, and permits only one crop a year on paddy fields. The Pacific coast of Tohoku, however, is generally much less snowy than the region's popular image and has among the smallest seasonal temperature variation in Japan. The city of Iwaki, for instance, has daily mean temperatures ranging from in January to in August.
