TOKYO, June 13 (Reuters) - The Nikkei stock average lost ground on Monday, hurt by a surprise fall in Japanese machinery orders, further signs of a global economic slowdown and a drop in shares of Toyota Motor after a weaker-than-expected earnings forecast.
Japan's core machinery orders unexpectedly dropped in April in a sign that disruptions to energy supplies are impeding capital expenditure although demand should later rise when the country rebuilds its earthquake-ravaged northeast coast.
The benchmark Nikkei fell 0.7 percent to 9,448.21, while the broader Topix shed 0.6 percent to 812.26.
