Tokyo stocks opened higher on Friday, extending rallies on Wall Street as worries over geopolitical risks linked to US-Iran tensions receded.
The benchmark Nikkei 225 index edged up 0.31 percent or 73.16 points to 23,813.03 in early trade, while the broader Topix index was up 0.35 percent or 6.07 points at 1,735.12.
Japanese shares are seen "dominated by buying, helped by rallies in US shares," with easing geopolitical concerns in the Middle East, said Toshiyuki Kanayama, senior market analyst at Monex.
The gains marked a second straight session of advances on rising confidence that the US and Iran would avoid all-out conflict, following statements Wednesday by US President Donald Trump and Iranian officials.
Investor sentiment was further boosted by China's announcement that Vice Premier Liu He will travel to Washington next week to sign the "phase one" deal with the United States that has lowered trade tensions between the world's two biggest economies, analysts said.
The dollar fetched 109.53 yen in early Asian trade, against 109.51 yen in New York late Thursday.
