TOKYO, Aug 25 (Reuters) - Bank of Japan board member Toyoaki Nakamura said on Thursday it was premature to change the central bank's dovish forward guidance to a more neutral one given sluggish wage growth.

On recent yen declines, Nakamura told a news conference there is not much the BOJ can do to address the currency's falls, as they are driven predominantly by changes in the U.S. economy and the Federal Reserve's interest rate hikes. (Reporting by Leika Kihara; Editing by Jacqueline Wong)
