Modern Japan offers us a view of a highly developed society with its own internal logic. Eiko Ikegami makes this logic accessible to us through a sweeping investigation into the roots of Japanese organizational structures. She accomplishes this by focusing on the diverse roles that the samurai have played in Japanese history. From their rise in ancient Japan, through their dominance as warrior lords in the medieval period, and their subsequent transformation to quasi-bureaucrats at the beginning of the Tokugawa era, the samurai held center stage in Japan until their abolishment after the opening up of Japan in the mid-nineteenth century.
