Naomi Osaka feels no 'extra pressure playing in Japan' after reaching Pan Pacific Open semis
US Open champion has too much firepower for Barbora Strycova in Tokyo, advancing to face Italy's Camila Giorgi in last four
Japan's Naomi Osaka exuded a major champion's aura on Friday as she dispatched Barbora Strycova 6-3, 6-4 to reach the Pan Pacific Open semi-finals, despite being nowhere near her best.
The third seed, who stunned Serena Williams to capture the US Open title earlier this month, failed to hit the same heights she did on that historic night in New York.
But she still had too much firepower for Strycova in Tokyo, advancing to the last four to face Camila Giorgi, who led Victoria Azarenka 5-3 before the former world No 1 was forced to retire after not feeling well.
Eighth seed Strycova had little answer to her opponent's venomous hitting and the world No 7 bagged the first set with a sledgehammer forehand that almost tore the racquet from the Czech's hand.
Osaka, 20, contesting her first tournament since becoming Japan's first grand slam singles winner, never looked back against a player 12 years her senior, another forehand rocket bringing up a first match point.
Strycova saved that one but moments later, Osaka fired a bruising serve into the body to extend her current winning streak to nine matches.
"I've played her three times and each time it's been very hard," said Osaka, who reached the Tokyo final in 2016.
"I don't feel any extra pressure playing in Japan," added Japan's latest sporting celebrity, who has a Japanese mother, a Haitian father and was raised in the United States.
"I've improved a lot of things in the last few years and I feel excited playing here."
Earlier, fourth seed Karolina Pliskova saved two match points before the former women's top-ranked player ended American qualifier Alison Riske's run with a 6-1, 6-7, 7-6 victory.
The Czech, who smashed a racquet in disgust after squandering multiple chances at 5-5 in the deciding set, completed a "lucky win" with a sliced backhand that Riske wafted into the net after two hours, 40 minutes.
"It was an important win for me," Pliskova said after reaching her first Tokyo semi-final.
"I saved a couple of match points - she was a little bit better than me but you need a bit of luck in tennis. I'm just happy to be able to fight back."
Pliskova faces Croatia's Donna Vekic in the last four after she upset second seed Caroline Garcia 6-3, 6-4.
Garcia blew an early break to allow Vekic to take the opening set and the Frenchwoman suffered a carbon-copy letdown in the second, the Croatian ending her misery with a backhand winner.
