Bank of Japan's Kuroda says they will do whatever it takes to beat deflation

Bank of Japan governor Haruhiko Kuroda has pledged that the central bank will do "whatever it takes" to beat deflation, as Japan's economic improvement steadily proceeds.

Kuroda cited signs of positive cycle of output, income and spending, but claimed that a proposed sales tax hike wouldn't derail Japan's economic recovery.

The central banker also warned that delaying steps to restore Japan's fiscal heatlh could create problems in the future.
