2) Japan ($10 trillion)

Unfortunate events like tsunami and nuclear plant meltdown have driven Japan to a debt of $10 trillion. That is $80,000 per citizen.

In 2011, Moody’s cut Japan’s long-term sovereign debt rating by one notch to Aa3 from As2. The good news is that the leaders of this nation are taking appropriate steps to handle the crisis.

For instance the government is planning to boost the national sales tax in 2017.
