Book excerpt: In Post-war Japan as a Sea Power, Alessio Patalano incorporates new, exclusive source material to develop an innovative approach to the study of post-war Japan as a military power. This archival-based history of Asia's most advanced navy, the Japanese Maritime Self-Defence Force (JMSDF), looks beyond the traditional perspective of viewing the modern Japanese military in light of the country's alliance with the US. The book places the institution in a historical context, analysing its imperial legacy and the role of Japan's shattering defeat in WWII in the post-war emergence of Japan as East Asia's 'sea power'.
