TOKYO (AP) — Japan’s benchmark Nikkei 225 share index soared as much as 10.7% early Tuesday, a day after it plunged a near record 12.4%. The index was up 3,360.39 at 34,818.81 about an hour after trading began. The gains followed sharp losses on Wall Street that were dramatic but not on the same scale as Monday’s debacle in Tokyo.

Japan’s Nikkei Stock Average had its worst day since 1987, falling 12.4% in a frenzy of selling triggered by disappointing economic data in the U.S. and a surge in the Japanese yen.

Japanese stocks collapsed on Monday in their biggest single day rout since the 1987 Black Monday sell-offs, driven by last week's plunge in global stock markets, economic concerns and worries investments funded by a cheap yen were being unwound.
