The Bank of Japan voted to keep interest rates near zero, holding off on further measures to tackle a strong yen that is undermining the country's fragile economic recovery.

In a unanimous decision, the nine-member BOJ Policy Board decided Tuesday to maintain the key interest rate at 0.1 percent, as widely expected. The BOJ has not changed the overnight call rate since December 2008.

The BOJ maintained its assessment of the economy, saying it shows "further signs of a moderate recovery" but acknowledged growing head winds.
