Japan PM Kishida: Specific monetary policy tools are up to BOJ to decide

• Expects BOJ to keep up monetary policy settings to achieve inflation target

They have previously been explicit about the BOJ maintaining its ultra easing policy to achieve the 2% inflation target, but are now saying that the central bank should achieve that "steadily and sustainably". Given Japan's predicament, it roughly means the same thing so I wouldn't look too much into the change in wording.
