The Bank of Japan kept its monetary policy unchanged Tuesday, deciding to keep the banking system awash with funds.

The decision reflects the central bank's view that despite the Cabinet Office's judgment last week that the economy has hit bottom, any export-assisted recovery will probably be weak.

The central bank will continue pumping money into private-sector banks' current accounts at the BOJ to keep the balance at around 10 trillion yen to 15 trillion yen, the Policy Board decided by unanimous vote.
