Tokyo stocks closed lower Tuesday in cautious trading ahead of results from several major companies, as investors largely ignored the Bank of Japan's policy decision. The benchmark Nikkei 225 index fell 0.46 percent, or 134.34 points, to 28,991.89, while the broader Topix index slipped 0.76 percent, or 14.60 points, to 1,903.55. si/kaf/axn
