Forget about Greece and Italy, when you look at the numbers, Japan poses the greatest worry.

This data visualization explores the growing but underreported problem of Japanese debt.

A nations debt to GDP ratio usually becomes worrisome near 90%; Japan is over 200%. Japan has more public debt than any other nation in the world. Despite being the 10th most populated nation, Japan owes a staggering $86,262 per person.

By looking at the chart at the bottom of the infographic, we see that Japan is able to borrow money at the extremely cheap rate of .98%. This has shielded Japan from many of the worries that plague European economies. However, as this number rises, we may be in for a debt crisis that far exceeds Greece and Italy combined.
