Line Corp. raised more than ¥100 billion from its consecutive debuts on the New York and Tokyo stock exchanges on Thursday and Friday, as CEO Takeshi Idezawa said the company planned to build trust in its messaging and other services and expand.

In the year's biggest tech offering, Line shares soared in both markets, closing at $41.58 in New York, up about 27 percent from the IPO price of $32.84, and at ¥4,345 in Tokyo, up from ¥3,300.

"We have so many Line users . . . We've gone public because we think it's important for a company that provides such communication infrastructure to improve the transparency of our management and win trust," Idezawa said at a news conference in Tokyo.
