TOKYO, Nov 13 (Reuters) - Japan's Nikkei stock average lost 0.4 percent on Friday, weighed down by selling of smelters after non-ferrous metals prices fell, with worries about consumer spending and Wall Street's performance leading to broad selling.

But buying of a range of defensive shares such as seafood company Nippon Suisan (1332.T: Quote, Profile, Research), which surged after a brokerage upgrade, kept the fall in check. A brokerage upgrade also boosted Sharp Corp (6753.T: Quote, Profile, Research) In thin trade, the benchmark Nikkei .N225 shed 34.18 points to 9,770.31, marking its third negative week in a row, the first such run since the three weeks ending Oct. 2. The broader Topix .TOPX lost 0.1 percent to 866.80. (Reporting by Elaine Lies)
