“Japan expects to spend a record $257 billion to service its debt during the next fiscal year, a document obtained by Reuters showed, underscoring the huge burden created by the government’s borrowings. That will be up 13.7 percent from the amount set aside for the current fiscal year, reflecting the ministry’s plan to guard against any future rise in long-term interest rates. Years of fiscal stimulus to revive a stagnant economy and surging social welfare costs for a rapidly ageing population have led to Japan running a record 1,000 trillion yen ($10 trillion) in public debt, double the size of its economy and the biggest among major industrialized nations.”
