Japan today is a nation synonymous with contemporary culture and ambitious technology that tries to transform the way in which we live. However, it is hard to imagine that just over a century ago; Japan was in the midst of a massive change which saw it go from a country of feudal military foundations to an industrious world power which would contribute to world history in a substantial way. This project aims to look at the History of Japan over the Meiji Restoration in the late 1800s and see how this event was the catalyst which caused a nation to turn its back on 800 years of uniform history and become a contending power on the world stage. The cultural principles of Japan at this time shall lead me to look at the post war writer Yukio Mishima, whose ideas on the culture of Japan after World War II provoked him to write some of the most defining Japanese literature of the 20th Century. Ultimately, his views in this area led to his highly publicised ritual suicide in 1970 prior to which he tried to start a coup against the new media based, industrial Japan. To link this project philosophically, I shall be referring the ideas of Mishima to those of Georges Bataille, who Mishima himself had a fascination with. Bataille’s theories brought forward notions related to sacrifice within a culture. This includes specifically the concept of Potlatch, wherein Native American tribal chiefs would appease opposing leaders by destroying resources and objects of value. With this in mind, I shall show how the Japanese transformation was a Potlatch on a grand scale, and how Mishima was a microcosm of this in the 20th Century. The conclusion of this project will come to the point where justification of Japan’s change will be shown.
