"The BOJ meeting - no surprises there and no surprises were expected," Ed Rogers, CEO of Rogers Investment Advisors, told CNBC Asia's "Cash Flow."
"We think the policy makers feel very comfortable right now and are very confident. We think we will see more accommodative policy if needed but don't expect any dramatic changes any time soon," he added.

The central bank maintained the policy frame-work it set up in April, when it said it would increase Japan's base money, the cash and deposits at the central bank, at an annual pace of 60 trillion yen ($597 billion) to 70 trillion yen, to boost inflation.
