The yen briefly weakened to a one-month low around the mid-132 range against the U.S. dollar Monday morning in Tokyo, after a report that the government has approached Bank of Japan deputy chief Masayoshi Amamiya as a possible successor to the central bank chief fueled expectations of continued monetary easing.
Tokyo stocks advanced in the morning as the yen's weakness helped lift exporter issues.
