Asian markets mostly rose Wednesday following big losses in the previous session, with Tokyo surging as the yen tumbled after Bank of Japan governor Masaaki Shirakawa said he will step down early. Traders also took a lead from Wall Street and Europe, where encouraging economic data offset concerns over political uncertainty in Spain and Italy. Tokyo\'s benchmark Nikkei index soared 3.37 percent, or 416.83 points, to 11,463.75 -- its highest close since September 2008 soon after the collapse of US bank Lehman Brothers and at the height of the financial crisis. In the months afterwards the Nikkei suffered more selling before it hit its bottom of 7,054.98 on March 10, 2009. On Wednesday, Tokyo\'s broader Topix index of all first-section shares also soared, by 3.10 percent, or 29.12 points, to 968.82. Shirakawa said on Tuesday he will step down about three weeks before his five-year term is due to end on April 8, after the BoJ and Japan\'s new government butted heads on policy matters. The country\'s new Prime Minister Shinzo Abe has openly said he wants a more like-minded candidate, fuelling expectations a new governor will take over who has similar views on following more aggressive monetary easing. Toyota shares closed 6.05 percent higher at 4,815 yen after the automaker late Tuesday said net profit in the nine months to December quadrupled while it also lifted its full-year earnings outlook. The weaker yen helped other exporters with Sony up 2.34 percent to 1,481 yen, Nikon rising 1.85 percent to 2,639 yen, Canon jumping 2.86 percent to 3,415 yen and Panasonic up 2.78 percent at 739 yen. The Sydney index climbed 0.78 percent, or 38.3 points, to 4,921.0 and Hong Kong added 0.47 percent, or 108.40 points, to 23,256.93, while Shanghai ended flat, edging up 1.35 points to 2,434.48. But Seoul lost 1.99 points to close at 1,936.19. Wellington was closed for a public holiday. Japanese foreign exchange traders welcomed Shirakawa\'s announcement that he would step down on March 19, about three weeks before the end of his term. It fuelled expectations that Prime Minister Shinzo Abe will likely fill the post with someone who shares his ideas on aggressive monetary easing that would see more yen pumped into the economy. The Japanese currency tumbled in New York. By the end of trade on Tuesday the dollar bought 93.61 yen and the euro was at 127.13 yen, compared with 92.28 yen and 124.67 yen earlier in the day in Tokyo. In afternoon Tokyo trade on Wednesday the dollar bought 93.70 yen and the euro fetched 126.90 yen. Yen \"weakness has resumed with a vengeance\", National Australia Bank said. Major Japanese exporters have been raising their earnings outlooks thanks to recent weakness in the yen, heartening investors. \"Global markets continue to normalise, allowing risk-on trading to resume,\" said SMBC Nikko Securities general manager of equities Hiroichi Nishi. \"This is partially reflected in the fall of the yen,\" he told Dow Jones Newswires.
