Tokyo stocks rose Friday morning as automakers and banks chalked up gains, while Toshiba erased early losses that had been driven by fears its loss-hit US nuclear unit is headed for bankruptcy.
The benchmark Nikkei 225 index rallied 1.33 percent, or 256.76 points, to 19,575.34 by the break and the Topix index of all first-section issues rose 1.09 percent, or 17.00 points, to 1,571.68.
Exporters benefited as the dollar hit 115.20 yen in Tokyo, against 114.95 yen in New York.
Eyes are on the release of US jobs data later Friday, which traders hope will provide a clearer idea about the Federal Reserve's future plans for interest rates after an expected hike next week.
"The yen's decline is a main factor behind today's solid gains," said Toshikazu Horiuchi, a broker at IwaiCosmo Securities.
"The market appears convinced that the Fed will raise rates, while investors are expecting encouraging US payroll figures. All in all, Tokyo market sentiment is upbeat."
In share trading Toyota rose 1.04 percent to 6,501 yen, while rival Nissan gained 1.18 percent to 1,155 yen.
Uniqlo operator Fast Retailing, a market heavyweight, rose 2.14 percent to 36,810 yen and Sony jumped 3.48 percent to 3,655 yen. On Thursday, Standard & Poor's raised Sony's credit rating, saying a wide-ranging restructuring had "greatly reduced the downside risk to earnings" in its hard-hit electronics business.
Banking giant Mitsubishi UFJ rose 1.41 percent to 767.6 yen and rival Sumitomo Mitsui Financial Group tacked on 1.18 percent to 4,377 yen.
Toshiba, which dropped more than three percent in early trade, ticked up 0.68 percent to 206.2 yen. It dived seven percent Thursday.
Toshiba has been reeling from huge losses at its US nuclear business, with fears mounting that the hard-hit unit is headed for bankruptcy.
