ABSTRACT

Typhoons approaching Japan usually move from west to east under westerly winds, with events moving from east to west along the Pacific coast being very rare. Nevertheless, such storms do take place from time to time, such as the typhoon that approached the Kanto region of Japan in August 1945. As the event took place before the surrender of the country during WW2, and thus before the US military moved in, detailed weather information (such as the exact path of the typhoon or its central pressure) were not collected. Typhoon Louise in 1963 also took a westward course and caused heavy damage to the country, mainly due to heavy rains. Typhoon Jongdari in 2018 was the first significant typhoon to take a westward course since that time, generating high waves along the western side of Sagami Bay.
