The yen surged after BOJ Governor Kazuo Ueda said the central bank could end its policy of negative interest rates when the achievement of its 2% inflation target is in sight.
Global shares, as reflected by the MSCI All-World index (.MIWD00000PUS), rose 0.1%, supported by a bounce in stocks in Europe, where the STOXX 600 (.STOXX) gained 0.3%.
Last week, the STOXX posted its longest stretch of losses in 5-1/2 years.
Economists polled by Reuters expect consumer prices to have risen by 3.6% from last year, up from July's 3.2% reading.
The ECB meets on Thursday to set interest rates and markets have all but priced out any chance of a hike.
