Abstract
Our study group is aiming to take valuable lessons of Project Management from some historical characters or occurrences. This time, I would like to report on 'Chugoku Ohgaeshi' project of Hashiba Hideyoshi which is one of the most famous occurrences in Japan's Sengoku Period (officially Azuchi-Momoyama Period). When Honnoji Incident happened near Kyoto in 1582, Hideyoshi was isolated in Takamatsu Castle in the Chugoku-Shikoku area (western part of Japan). But in the end, Hideyoshi rapidly avenged his assassinated boss, Oda Nobunaga, and opened the door for the national unification of Japan. How did he get over the difficulty and turn the tide? I considered these questions from the viewpoint of PM. I referred to a few books on this report but after all my emphasis concerning the historical character and interpretation is the one having put it on the aspect of PM.
