TOKYO, Oct 28 (Reuters) - As his term winds down, Bank of Japan Governor Haruhiko Kuroda has retreated from both the radical policies and rhetoric of his early tenure, suggesting there will be no further monetary easing except in response to a big external shock.

In a clear departure from his initial "shock and awe" tactics to jolt the nation from its deflationary mindset, he has even taken to flagging what little change lies ahead, trying predictability where surprise has failed.

This new approach will be on show next week, when the BOJ is set to keep policy unchanged despite an expected downgrade in forecasts that could show Kuroda won't hit his perpetually postponed 2 percent inflation target before his five-year term ends in April 2018.

"The days of trying to radically heighten inflation expectations with shock action are over," said a source familiar with the BOJ's thinking. "No more regime change."

Kuroda told parliament last week that while the BOJ might again stretch the timing for its inflation target, he saw no need to ease at the Oct. 31-Nov. 1 policy meeting.

"There may be some modification to our forecast that inflation will hit our 2 percent target during fiscal 2017," he said, the first time he has offered hints on upcoming projections.

Japan's core consumer prices fell for a seventh straight month in September as household spending slumped, data showed on Friday, reinforcing the view it will take some time for inflation to accelerate to its target.

In the past, the market has learned to expect the unexpected.

In 2013, when the BOJ deployed its massive asset-buying programme, dubbed "quantitative and qualitative easing" (QQE), his shock therapy boosted stocks and weakened the yen.

Further surprises came with an expansion of QQE in October 2014, and then the switch to negative rates early in 2016, which he had denied was an option just days before.

But the law of diminishing returns bought him less bang for each buck.

"When monetary policy options begin to wear out, the shock approach doesn't work any more," said Toshiro Mutoh, former BOJ deputy governor and now chairman of Daiwa Institute of Research.

"That's why the BOJ needs to avoid surprising markets and make its intentions more predictable through guidance."
