The Nikkei held gains from the morning, fluctuating very little following the midday break, to end the day 2.09% higher at 26,717.34. It was its first session of gain in four, with nearly 10 stocks rising for every one that fell.
"There's a feeling that the sell-off has gone too far, so it's natural for there to be some buying back of shares," said Koji Toda, a fund manager at Resona Asset Management.
"If gains slow close to 27,000, it could be a sign of more turbulence ahead."
