The Bank of Japan (BOJ) is one of the main focuses of investors this week which will see further monetary policy setting from the central bank on Thursday.
With the yen still hovering around its weakest level since 1998, authorities have given indications of taking action to stem the currency's decline.
As a result, analysts see it likely to start offering signals to move away from its ultra-loose monetary policy at this week's meeting.
Even so, interest rates are expected to remain unchanged at -0.10% and the 10-year Japanese government bond yield target is around 0%.
Widening policy divergence with the Federal Reserve (Fed) has caused the yen to weaken significantly, plunging about 25% so far in 2022.
Last week, the Nikkei reported the central bank had conducted a rate review in apparent preparation for currency intervention.
The review is said to involve scrutiny of trends in the foreign exchange market and is widely seen as a trigger for physical intervention to defend the yen.
Inflation data published on Tuesday showed price pressures in the country remained under control despite rising to a new 8-year high of 2.8% in August.
