Possible government regulation of the tech sector has rattled investors, with Amazon losing over $30 billion of its market value in overnight trade on a report U.S. President Donald Trump wants to rein in the growing power of the world's largest online retailer.
"Fears of a global trade war have eased, although concerns still linger about the U.S. technology sector," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui Asset Management in Tokyo.
"But equities in Asia will receive support from an easing of tensions regarding North Korea, with countries like Japan seeking a summit," Ichikawa added.
Japan has sounded out the North Korean government about a bilateral summit, and Pyongyang has discussed the possibility of a leaders' meeting with Japan and other countries, Japan's Asahi newspaper said on Thursday.
Earlier, North Korea's leader Kim Jong Un pledged his commitment to denuclearisation and to meet U.S. officials, Beijing said on Wednesday after Kim met with Chinese President Xi Jinping.

Focus was on whether the Trump administration would press China for currency reassurances as part of the trade negotiations, like those secured from South Korea.
Fears of a full-blown trade war have eased on hopes that negotiations can foster a compromise, but concerns remained.
"Expansionary U.S. fiscal policy should support global trade, but markets will remain attentive to further tensions as the China-U.S. trade saga continues to unfold," wrote economists at ANZ.
