The yen was last down about 0.15% at 136.36 after a knee-jerk plunge of as much as 0.62% after the BOJ kept policy unchanged in Governor Haruhiko Kuroda's final policy meeting before retirement. Despite some volatility against the yen, the U.S. dollar was mostly flat on Friday. Against a basket of currencies, the U.S. dollar index was little changed at 105.28 but remained on track for a weekly gain of 0.73%. The focus now turns to the closely watched nonfarm payrolls report later on Friday, the next major data point that could offer clues on the Fed's next steps for monetary policy. According to a Reuters survey of economists, nonfarm payrolls likely increased by 205,000 jobs in February after surging by 517,000 in January.
