TOKYO, April 1 (Reuters) - The Nikkei average rose 1.4 percent on Tuesday, led higher by exporters such as Canon Inc <7751.T>, tracking gains on Wall Street.
The market rebounded from a tumble on Monday, despite the weaker-than-expected results of a Bank of Japan tankan business sentiment survey.
"There was not much surprise in the tankan. The market has already priced in weak readings," said Harushige Kobayashi, head of research at Maruwa Securities. "It's natural to see a rebound of this size, given yesterday's sharp fall."
Business sentiment among big Japanese manufacturers sank to a four-year low in the March tankan, adding to evidence of a worsening economic outlook and reinforcing some market speculation that the central bank may cut interest rates later in the year.
Worries about the global credit crunch, rising raw material costs, fragile stock prices, and a rise in the yen contributed to weakening business confidence, and the outlook for the coming quarter was even more bleak. [
]Trade in Tokyo remained thin, with investors opting to sit tight ahead of a raft of economic data and earnings from U.S. banks later in the month.
"Investors don't feel an urgent need to buy any particular sector, and they are also holding off ahead of earnings," said Norio Shimura, deputy head of the equity department at Chuo Securities.
