TOKYO, Aug 6 (Reuters) - Japan's Nikkei share average reversed early losses to trade higher on Wednesday, as concerns about the U.S. economy receded, prompting investors to continue buying cheap stocks after a heavy sell-off earlier this week.
The Nikkei .N225 rose 0.62% to 40,802.73 by the midday break, reversing a 0.3% decline earlier in the session.
The broader Topix .TOPX jumped 1.12% to 2,969.55, supported by 2% gains for each of Toyota Motor 7203.T and Sony Group 6758.T.
"Investors bought stocks because the gains of the Nikkei in the previous session were not enough to recoup declines on Monday," said Naoki Fujiwara, senior fund manager at Shinkin Asset Management.

Mitsubishi Heavy Industries 7011.T rose 4.19%, jumping for a second session, after the heavy machinery maker clinched a landmark deal to build Australia's next-generation warships.
