Tokyo's benchmark Nikkei index gained more than 1.8 percent on Thursday with market sentiment buoyed by a rally in Wall Street shares after the US midterm elections produced no major surprises.
The Nikkei 225 index rose 1.82% to 22 486.92, while the broader Topix index was up 1.74% or 28.82 points at 1 681.25.
"Buying sentiment spread as the market took a positive lead from Wall Street, erasing initial concerns about the US elections," said Toshikazu Horiuchi, a broker at IwaiCosmo Securities.

On Wednesday, the Japanese bourse closed lower as investors were still digesting the US vote result - a split Congress that analysts say is likely to halt any major advances in President Donald Trump's economic agenda.
"Following the vote, the market shifted its focus to the FOMC (Federal Open Market Committee)," Horiuchi told AFP.
The Federal Reserve will end its two-day policy meeting later in the day, with central bankers widely expected to hold their fire but likely to signal a December rate hike.
"And the market is also refocusing on the prospect of a US-China trade war," he added.
