TOKYO, Sept 30 (Reuters) - Japan's copper wire and cable makers said on Friday they expect shipments of 668,000 tonnes in the year to March 2012, down 2.2 percent from the previous year.
Wire and cables are the biggest application of copper in Japan, the world's second-biggest consumer after China.
Japan is also the biggest supplier of copper products to China.
Japan's appetite for copper, often seen as a gauge of economic activity and already weak in the wake of the global financial crisis, took a fresh beating after the March 11 earthquake and tsunami prompted user industries to reduce domestic production.
