Top seeds Kento Momota and Tai Tzu-ying booked their places in the second round of the men's and women's singles respectively on day one of the Badminton World Federation Indonesia Open in Jakarta.
A strong line-up has gathered at the Istora Gelora Bung Karno for the prestigious event which is a Super 1000 tournament on the BWF World Tour – the very top tier.
Japan's Momota, the reigning world champion and world number one, knocked out Malaysia's Liew Daren 22-20, 21-14 in his first round clash.
It means the 24-year-old is on track to defend the title he won in Indonesia last year and claim it for a third time in all.
None of the seeded players were knocked out as the top half of the draw took centre stage on day one, with Chinese Taipei's Chou Tien-chen among the other contenders going through.
The fourth seed was too strong for Thailand's Suppanyu Avihingsanon, winning 21-12, 21-11 at the venue which was used for the 2018 Asian Games.
Indonesia celebrated double joy on home ground as their fifth seed Jonatan Christie and sixth seed Anthony Sinisuka Ginting both advanced.
Asian Games gold medallist Christie defeated Rasmus Gemke of Denmark 21-17, 24-22 as Ginting came from behind to oust China's Lu Guangzu, 20-22, 23-21, 21-18.
Beijing 2008 and London 2012 Olympic champion Lin Dan survived a scare as the Chinese icon battled back to defeat Canada's Jason Ho-shue 14-21, 21-16, 21-16.
Players involved in tomorrow's bottom half of the draw include China's Shi Yuqi and Chen Long, the number two seed and reigning Olympic champion respectively.
In the women's event Tai also enters as the world number one and defending champion, as well as being the current Asian Games gold medallist.
The Chinese Taipei player knocked out Singapore's Yeo Jia Min 21-12, 21-18.
As with the men's event the seeds all survived in the top half of the draw but Japan's fourth-ranked Akane Yamaguchi needed three games to beat China's London 2012 Olympic champion Li Xuerui 18-21, 21-10, 21-15.
Seventh seed Ratchanok Intanon of Thailand, a former world champion, beat Indonesian home hope Ruselli Hartawan 21-14, 21-14.
The home team did see a player go through, however, as Gregoria Mariska Tunjung knocked out Pornpawee Chochuwong of Thailand 21-10, 21-8.
Tomorrow sees players including Japan's 2017 world champion Nozomu Okuhara, the third seed, and India's fifth seed PV Sindhu take to the court for their first round matches.
The tournament, also including men's, women's and mixed doubles, will conclude with finals on Sunday (July 21).
