Japan Open Super Series tennis gets underway with the qualifiers in Tokyo tomorrow. The Indian challenge at the sporting event will be led by P V Sindhu and K Srikanth as ace shuttler Saina Nehwal has decided to skip the Japan Open due to fatigue after a gruelling Uber Cup campaign. She would concentrate on the next two events at Indonesia and Australia later this month. In Saina's absence, Sindhu and young Tanvi Lad will represent India in women's singles, while Srikanth will spearhead the challenge in the men's singles.
