TOKYO: Tokyo stocks closed higher Thursday, as a result in US presidential election appeared imminent. The benchmark Nikkei 225 index ended up 1.73 percent or 410.05 points at 24,105.28 while the broader Topix index was up 1.39 percent or 22.69 points at 1,649.94. The prospect of an election win for Joe Biden was fuelling the gains, Okasan Online Securities chief strategist Yoshihiro Ito said in a commentary.

The knife-edge presidential race has tilted toward Democrat Biden with wins in Michigan and Wisconsin bringing him close to a majority, but President Donald Trump claimed - without offering any evidence - that he was being cheated and went to court to try and stop vote-counting.
