Surprisingly, is Japan a country that managed its national debt very well?..

You might ask what I'm talking about, given that Japan has the highest national debt-to-GDP ratio in the world.
However, if you look strictly at the volume of debt, Japan is a country with a very, very low growth rate.
But because GDP is stagnant or shrinking,
even a tiny increase—or even if the debt amount doesn't increase at all—
it creates a structure where the proportion relative to GDP naturally grows...
This happened because, due to the lack of inflation, it is impossible to "melt away" the debt by growing the economy's size..
