General Motors Corp.'s filing for bankruptcy protection Monday will have a wide impact on Japan's economy, ranging from further reduced U.S. consumption and car sales to fallout hitting the nation's parts makers, experts said.

The largest industrial bankruptcy in U.S. history is expected to push down U.S. gross domestic product by 0.03 percentage point because it will idle around 114,000 GM assembly workers and dealership employees, putting a further damper on household spending, said Takahide Kiuchi, chief economist at Nomura Securities Co.

The weaker consumption in turn will push down Japan's GDP by about 0.02 point through a fall in sales of Japanese cars, he said.
