SoftBank ended the day up 1.9 percent, after surging nearly 5 percent at one point following a strong earnings report.

Social network operator Mixi Inc also outperformed, soaring 11.9 percent after announcing it would spend up to 10 billion yen ($92.03 million) to buy back up to 3 million of its shares, a 3.5 percent stake.
The broader Topix was flat at 1,334.30 and the JPX-Nikkei Index 400 edged down 0.1 percent to 12,059.51.
