The U.S. business community is urging Japan to pursue reforms that will help the economy and attract more American investment, the visiting chairman of the U.S. Chamber of Commerce said Friday.

Economic reforms currently pressed by Prime Minister Junichiro Koizumi would increase the certainty of business operation in Japan and thus help American companies to invest in the country, said Steve Van Andel, who is also chairman of Alticor Inc., the parent company of Amway Corp.

"When businesses look at investment at some place, they look for a certain amount of certainty," he said in an interview in Tokyo. "And the direction toward economic reforms gives such certainty and helps make a market more interesting, particularly for U.S. businesses to come over and invest."
