Devastating natural disasters struck Japan on March 11, 2011 leaving some 340,000 citizens refugees, and nearly 20,000 dead or missing. The 9.0 magnitude Great East Japan Earthquake and the ensuing tsunami wrought destruction on all facets of Japan’s infrastructure and have been declared the most costly natural disaster in world history. Despite the biblical scale of the catastrophes, within seconds of the disaster a complex network of sensors delivered a flurry of critical information into multi-stakeholder disaster networks that conveyed over diverse physical infrastructure life-saving warnings to the public, without a single accident safely brought to a halt speeding trains across the country, halted factories and elevators, and set in motion other important disaster responses. Japan's decades of preparation and investment were observed to demonstrate the value of communications in achieving key public safety goals of protecting life and property. The paper reviews the key national law foundations for disaster planning and management, regulatory facets of disaster networks and warning systems, the role of industry in preparation and participation in disasters, and citizens' role in communications aspects of Japan's survival of the 311 disasters. The paper identifies important comparative observations with U.S. approaches and experiences for the role of communications in disaster detection and warning, carrier and infrastructure preparedness, refugee assistance and support, social and other new media, and other emerging topics. More than one year later, Japan's ongoing policy responses and developments are reviewed to identify important lessons learned for researchers and policy makers.
