The transformative potential of blockchain technology can impact a wide array of industries and geographies. This book focuses on blockchain's particular implications for Japan. The topics covered are relevant to innovation ecosystems worldwide; however, we believe that Japan is the most interesting place to start. Developed societies across the globe are increasingly facing challenges arising from the trends of corporate stagnation, aging populations, talent mismatch, urbanization, automation, and decentralization. We believe that these challenges will affect almost all developed countries but are manifesting themselves most acutely in Japan first. Yet challenges create opportunities. Given its status on the front lines, Japan, we imagine, can be an early market in which the ensuing innovations take shape.Profits from the sale of this book are directed to Japan's Tohoku region, still rebuilding from the Great East Japan Earthquake.
