The new governor of the Bank of Japan Haruhiko Kuroda has succeeded in persuading the bank's board to adopt aggressive measures to try and end more than a decade of deflation.
The central bank vowed to boost an asset purchase programme and meet a 2% inflation target in two years, after a two-day meeting, the first chaired Mr Kuroda.
Speaking to Today business presenter Simon Jack, Dr Seijiro Takeshita, director of Mizuho International, said that the move would "not necessarily" awaken the country from its economic coma.
