Mount Ontake
General Kōichi Isobe was the 37th Commander of the Eastern Army in his final two years of service. The Eastern Army's area of responsibility covers the Tokyo Metropolitan Government and ten prefectures, and nearly half of the Japanese total population and GDP. During his tenure, he deployed more than 100,000 JSDF personnel in three major disasters: the October 2013 Pacific typhoon season flood and landslide on Izu Ōshima, February 2014's record-breaking snowfall in the Kantō region, and the September 2014 Mount Ontake eruption.
