For a long time Japan has upheld the values of pacifism, democracy and industrial and economic prosperity. However, protection of these values seems to be at stake now as Japan is grappling with a number of challenges on the domestic and foreign policy fronts. Various scholarly works have been undertaken to research these challenges. However, given the limited scope of these studies, they have so far failed to offer a comprehensive view of all the major challenges. This book rectifies that and offers an in-depth analysis of nine major challenges faced by Japan. In doing so, the authors build nine worst case scenarios and offer some policy recommendations to address them.
