As the U.S.-Japan Business Conference kicked off Thursday in Tokyo, Keidanren chief Hiromasa Yonekura called on domestic and American business leaders to reaffirm stronger bilateral ties and tackle issues troubling the global economy.

Speaking at the annual meeting, Yonekura, chairman of the country's largest business lobby, voiced concern that China and other emerging economies, the major engines for worldwide growth, have begun to slow.

"I sincerely hope that this year's conference will serve as an excellent opportunity for our two business communities to reaffirm the strength" of their partnership and discuss what both countries can do to address a host of challenges, said Yonekura, who is chairing the 49th annual conference with Aflac Japan Chairman Charles Lake through Friday.
