Japan has a new prime minister.

In August, Naoto Kan stepped down as the country’s prime minister.

He said he had failed the country by not doing a good job of helping Japan recover after it was rocked by an earthquake last March.

On March 11, the fifth most powerful earthquake in history took place in the sea off the coast of Japan. It caused a tsunami, or giant sea wave.

Waves up to 10 metres high flooded the coast of Japan, causing massive damage to many homes and to a nearby nuclear energy plant.

In addition to the problems caused by these natural disasters, Japan also has the largest debt of any country in the world.

Debt is the money the country owes to other countries and to banks.
