What started as a plan to reduce the national debt is turning into a reason to issue more bonds.

Prime Minister Shinzo Abe¡¯s administration implemented a higher consumption tax in April to boost revenue as government liabilities ballooned to ?1 quadrillion ($8.5 trillion), more than double the nation¡¯s yearly economic output.

Consumption plunged and the economy fell into a recession, prompting companies including Mirae Asset Global Investments Co. and High Frequency Economics to predict even more sovereign debt sales to revive growth.
