It is believed in the next 30 years as of January 1st, 2018 there is a 70-80% possibility that the Nankai Trough off Japan will have its next megaquake. This will become the most destructive natural disaster in human history crippling Japan and in particular severely affecting the cities of Nagoya, Osaka, and Tokyo. It is estimated damages from this event will approach 2 Trillion (USD) in today's dollars eclipsing the current record holder most expensive disaster 2011's Tohoku Earthquake which caused between 200 billion - 300 billion dollars worth of damage. Death tolls from this event in a worst case scenario would also likely be more than 10 times the Tohoku Earthquake and potentially worse than the 2004 Indian Ocean Earthquake and Tsunami with a final death toll of up to 323,000 people possible depending on the time and severity of the quake. The quake and resulting tsunami destroys much of Japan's critical infrastructure in affected regions. Food, water, electricity, and cellular service disappear for days and in some places weeks or months.
