Japan: Memoirs of a Secret EmpireExplores the period between the 16th and 19th centuries in Japan by examining the lives of shoguns, samurais, geishas, and the very few westerners allowed into Japan. Japan was then a world unto itself, closed to outsiders, and ruled by shoguns with absolute control. During this period, Japan transitioned from chaos and violence to a land of ritual refinement and peace.
