Aluminum stockpiles in Japan dropped 1.2 percent in April from March, the second straight month of decline, according to Marubeni Corp., Japan's largest importer of the metal.
Inventories in Yokohama, Nagoya and Osaka ports decreased to 190,500 metric tons as of April 30 from 192,800 tons at the end of March, said Yutaka Ishibashi, general manager at Marubeni's light metals section.
"Stockpiles fell on active shipments of the metal from warehouses and on delayed arrival of South American cargo," he said by phone today.
Stockpiles fell to 169,900 tons in September, the lowest level since Marubeni began compiling data in June 1995, after importers slashed the volume of purchases on expectation that demand would weaken amid an economic slump.
