Tokyo's Nikkei 225 index gained 0.3% to 40,074.87 after the central bank raised its benchmark rate to about 0.5% from 0.25%, as widely expected. It is the highest level for the rate since 2008, as the Bank of Japan shifts out of a long spell of extreme low interest rates meant to spur more borrowing and spending.

World shares advanced Friday after U.S. stocks rose to a record and the Bank of Japan raised its key lending rate.
