The next governor of the Bank of Japan faces a "job from hell."

That's according to Takeshi Fujimaki, a banker-turned-lawmaker who sees any attempt by the central bank to exit its program of unprecedented easing as triggering a Greek-like debt crisis.

"This is the calm before the battle," Fujimaki, an Ishin no To (Japan Innovation Party) politician who once served briefly as an adviser to George Soros, said in an interview at his Tokyo office Monday.
