Japan’s Yamaguchi beat Indonesia’s Gregoria Mariska Tunjung 21-12, 21-15 in front of an appreciative home crowd in Tokyo to kick off her hunt for a second straight world title.
“I wasn’t really nervous but you do get players who lose in the first round and go straight out, so I was really focused on getting the result,” said 25-year-old Yamaguchi.
“I never felt that I had any breathing space until towards the end of the second game. It was more about dealing with my opponent than me going on the attack.”
Spain’s Carolina Marin, who is aiming to win a record fourth world title in Tokyo, got her campaign off to a steady start with a 21-16, 21-14 win over Canada’s Wen Yu Zhang.
Former world No 1 Marin endured a horror 2021, missing both the pandemic-delayed Tokyo Olympics and the World Championships in her hometown of Huelva after suffering an ACL injury.
Marin returned to action in April this year but she said today that she was “not 100% yet”.
“This is the condition that I have right now and I have to play in this condition,” said Marin, seeded No 5 for the competition.
“Let’s see how far I can go in this tournament. Of course I want to get a medal here and I want to win, but this is not something I have in my mind.”
There were also first round wins for South Korean No 3 seed An Se-young – 21-18, 21-10 over Vietnam’s Thuy Linh Nguyen – and India’s Saina Nehwal, who beat Hong Kong’s Cheung Ngan Yi 21-19, 21-9.
On the men’s side, Denmark’s Axelsen was pushed hard in the first game of his second round match against Mark Caljouw of the Netherlands before hitting his stride in a 21-19, 21-10 win.
Axelsen has lost only one match on tour this season and he was again ruthless in putting away Caljouw.
“Mark played really well in the first game and made it really hard for me, especially on that far side where the drift is a little bit hard to deal with,” said Axelsen.
“I’m really happy that I managed to turn it around, it’s good to be in the third round and I’m really looking forward to it.”
Men’s No 2 seed Kento Momota will play India’s HS Prannoy tomorrow.
China’s Shi Yuqi, who is returning from a 10-month ban from the Chinese Badminton Association, continued his comeback with a 21-13, 21-16 second round win over Denmark’s Rasmus Gemke.
Shi, a world finalist in 2018, retired during a 2021 match against Momota and was banned by the Chinese Badminton Association for making “inappropriate comments” about his withdrawal.
He said he was “trying to prepare myself mentally to get better and better” after beating Gemke.
“I’m just taking it one step at a time but I’m hoping to get to the final and win the title,” he said.
