Japan's debt hit a record high of $10.54 trillion at the end of June amid massive government bond issuance and declining tax revenues, a data by the Finance Ministry has shown.
It is the first time that the debt balance, including government bonds and financing bills, has exceeded $10.49 tril.
Per-capita debt came to around $80,000 based on Japan's estimated population of about 127.42 million as of July 1.
The debt is equivalent to almost 1.9 times the nominal gross domestic product in fiscal 2009, which totaled $5.55 trillion.
Under its medium-term fiscal management plan through fiscal 2013 announced in June, the government is aiming to keep annual spending below $83 billion, the same level planned for fiscal 2010, and government bond issuance below $51 billion.
In its longer-term plan, the government will aim to bring the primary balance for both the central and local governments back into surplus by fiscal 2020 after halving the deficit by fiscal 2015.
