Reigning women's champion and top seed Akane Yamaguchi cruised through her opening game at the World Badminton Championships on Tuesday, while men's number one Viktor Axelsen continued his smooth progress.

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 number one 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 but she said Tuesday that she was "not 100 percent yet."

"This is the condition that I have right now and I have to play in this condition," said Marin, seeded number five 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 number three seed An Se-young - 21-18, 21-10 over Vietnam's Thuy Linh Nguyen - and India's Saina Nehwal, who beat Cheung Ngan Yi from Hong Kong, China 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 number two seed Kento Momota will play India's HS Prannoy on Wednesday.

China's Shi Yuqi beat the 11th seed Rasmus Gemke of Denmark to reach the last 16 at the World Badminton Championships on Tuesday.

Shi, who returned to action at the tournament after a 10-month suspension, took 46 minutes to down the Dane 21-13, 21-16 in the second round.

The 2018 worlds finalist has slipped to 25th in the world rankings after a long absence, but he proved much stronger than what the ranking place has suggested.

He rated his performance "7 out of 10," one point more than his first round show.

"I played much better than the first match, although there is still a long way from my best badminton," he said.
