Tokyo stocks rose on Tuesday, driven higher by a brisk performance from the construction sectors, but investors remained cautious over the US-China trade deal and fresh unrest in Hong Kong.
The benchmark Nikkei 225 index gained 0.81 percent, or 188.17 points, to close at 23,520.01, while the broader Topix index was up 0.33 percent, or 5.64 points, at 1,709.67.
"Investors were chasing companies such as construction firms that showed strong results," said Yoshihiro Okumura, general manager at Chibagin Asset Management.
"But profit-taking could easily emerge as the Nikkei has risen sharply in recent trading," Okumura told AFP.
Yoshihiro Ito, chief strategist at Okasan Online Securities, said in a commentary that stocks had struggled to rise in early trade after "mixed US shares, uncertainties over US-China trade talks, and unrest in Hong Kong."
Traders were trying to interpret US President Donald Trump's latest comments on US-China trade and were unsettled by the increasing violence in Hong Kong, where police shot one person and another man was set alight.
The dollar fetched 109.18 yen in Asian afternoon trade against 109.95 yen in New York late Monday.
In Tokyo, the construction sector was sharply higher. Obayashi surged 5.95 percent to 1,193 yen and Shimizu jumped 3.09 percent to 1,065 yen.
Nissan rose 1.00 percent to 714.5 yen. The firm is due to release its first-half earnings report after the closing bell on Tuesday with investors bracing for more poor results.
Chip-linked shares were higher, with semiconductor testing equipment maker Advantest gaining 3.49 percent to 5,620 yen and chip-testing equipment manufacturer Tokyo Electron up 0.96 percent at 22,075 yen.
