Asian markets were mixed on Wednesday following a strong lead from Wall Street, with investors biding their time as they await the end of a crucial Federal Reserve policy meeting.
With few other trading cues, the main focus is on the Fed meeting, which is expected to see policymakers begin reeling in the bank's massive stimulus programme.

"Japan stock investors are encouraged by the relative resilience in both the dollar and in US indices' apparent acceptance of at least a modest amount of Fed tapering," said Tachibana Securities market adviser Kenichi Hirano.
