Japanese stocks climbed, with the Nikkei 225 Stock Average poised for its strongest close since March 2011, after shares tracked gains in Asian markets and a weaker Yen increased the earnings outlook for traders. The Nikkei 225 surged 2.6% to 10,663.08, while the broader Topix Index advanced 2.9% to 884.33. The Yen slid to the lowest in two-and-half years versus the greenback, poising for a 2% drop this week and increasing eighth week losses.
