Stocks of aluminum at Japan's large ports fell 2.2% in May compared with April, a Japanese trading house said on Wednesday.
Stocks totaled 272,300 metric tons--with 140,500 tons in Yokohama, 116,800 tons in Nagoya and 15,000 tons in Osaka.
While the on-month decline signals a modest increase in demand in Japan May stock levels are almost 22.0% higher than a year ago when they were 223,200 tons.
