Apart from Srikanth and Lakshya, B Sai Praneeth, the bronze medallist of the 2019 edition and HS Prannoy are also capable of springing a surprise. World No. 33 Saina Nehwal, unseeded this time, will be looking to return to form at the Tokyo event. The former World No. 1 will try to gain the upper hand in the absence of Nozomi Okuhara and PV Sindhu.
