The first-ever summit between sitting leaders of the two foes went "better than anybody could have expected", said Trump.
Tokyo: Tokyo stocks gained on Tuesday, extending rallies on Wall Street as investors largely welcomed a historic summit between the United States and North Korea.
The benchmark Nikkei 225 index rose 0.33 per cent or 74.31 points to close at 22,878.35, while the broader Topix index was up 0.33 per cent or 5.98 points at 1,792.82. "The market largely welcomed the US-North Korea summit," said Hikaru Sato, senior technical analyst at Daiwa Securities.
"The fact that the summit took place without a breakdown can be regarded as a positive factor," Sato told AFP. "But we will have to keep an eye on the two countries for now as they have just begun the process."
US President Donald Trump said there had been a "lot of progress" in his talks with North Korea's leader Kim Jong Un, before the pair signed a document together.
The first-ever summit between sitting leaders of the two foes went "better than anybody could have expected", said Trump, who is scheduled to hold a news conference later in the day.
"Stocks this week will face a series of events... namely the US-North Korea summit and central bank meetings in Japan, the US and Europe," Masayuki Toshida, senior market analyst at Rakuten Securities, said in a commentary.
"In addition, worries over trade frictions caused by protectionist US economic policy still linger," he said. The direction of the market could change dramatically depending on developments in these events, he said.
