Lee Chong Wei qualified for the Japan Open main event after winning both his qualifying matches in Tokyo on Tuesday.
In his first match, the former world number one made short work of Alistair Casey, beating the Scottish shuttler 21-3, 21-3 in just 23 minutes.
His second and final match of the day saw the Malaysian star trump Kwang Hee Heo, beating the Korean 21-10, 21-12.
In the first round of the main event in Japan, Chong Wei will face Boonsak Ponsana.
Should he beat the Thai shuttler, a second round match against long- time rival Lin Dan awaits Chong Wei while the winner will take on world number one Chen Long in the quarter-finals.
Chong Wei's Malaysian counterpart Iris Wang, who was the top seed in the women's qualifying draw, was unsuccessful in her bid to qualify for the main event, though.
After receiving a bye into the second round of qualification, Wang failed to impress in her match against Kana Ito, eventually losing 21-19, 21-19 to the Japanese.
In the men's draw on Wednesday, top seed Long faces England's Rajiv Ouseph, Kidambi Srikanth faces Ireland's Scott Evans, local favourite Kento Momota takes on Wei Nan, while Dan opens his campaign against Son Wan Ho.
In the women's draw, world number one Carolina Marin faces another local player Yui Hashimoto in her first round, while Saina Nehwal comes up against Busanan Ongbumrungpan.
Third seed Li Xuerui faces Lindaweni Fanetri and Tai Tzu Ying faces qualifier, Kana Ito.
Men's second seed Jan O Jorgensen withdraw on the eve of the event.
