Tokyo stocks rose Friday with automakers and banks rallying, while Toshiba erased early losses despite fears that its troubled US nuclear unit is headed for bankruptcy. Exporters benefited as the dollar punched above 115 yen for the first time since the end of January, ahead of a key US jobs report likely to seal the case for the Fed to raise rates. Sentiment also got a lift after European Central Bank President Mario Draghi on Thursday offered an upbeat outlook for the eurozone economy.
"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."
A cheaper yen boosts the profitability of Japan's major exporters, stoking demand for their shares.
