Japan stocks fall after concerns for US economy

Japan's Nikkei 225 fell today amid a stronger yen and signs of a slowing US economy, while other key Asian stock indexes were closed for a public holiday.

The Nikkei Stock Average in Tokyo fell 1% to 9,422.83. Export shares struggled as the dollar hovered below the 80-yen mark. The greenback has not been this weak against the Japanese currency since February.
