TOKYO, July 29 (Reuters) - The Nikkei average fell 2.2 percent on Tuesday, with financial shares sliding as worries about the U.S. credit market mounted while automakers were hurt after Toyota Motor Corp <7203.T> cut its global sales forecast.
As investors jitters grew again about the potential for more U.S. bank losses to wreak further damage to the slowing U.S. economy and the global economic outlook, exporters like Canon Inc <7751.T> skidded.
"The uncertainty in the global economy is pushing down exporters, while the downward revision to sales forecasts by Toyota is weighing heavily on automakers," said Yoshinori Nagano, chief strategist at Daiwa Asset Management.
He added that while Japanese financial shares were tracking their U.S. peers, their stronger fundamentals meant they would not fall as hard.
