Tokyo - Tokyo stocks rose on 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 256.76 points, to 19 575.34 by the break and the Topix index of all first-section issues rose 17.00 points, to 1 571.68.
Exporters benefited as the dollar hit ¥115.20 in Tokyo, against ¥114.95 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."
