The impact of the dramatic monetary policies adopted last week by the Bank of Japan was "within expectations," but the bank will keep a close watch on markets, BOJ Gov. Haruhiko Kuroda said Wednesday.

Speaking during a joint interview with The Japan Times and other media outlets, Kuroda reiterated that the policies revealed on April 4 were "considerably different from previous easing" by the BOJ and that it may take a while for the ripples to calm.

The former Asia Development Bank chief has become the man of the hour after his quantitative and qualitative easing caused a quick depreciation of the yen and stocks to soar.
