Players earned points based on their performances in the singles and doubles tournaments at the 12 events of the 2018 ITTF World Tour. The top 16 men's and women's singles players, and the top eight men's, women's and mixed doubles pairs who satisfied the qualification criteria were invited to compete. China's Ma Long qualified for the men's singles event, but withdrew due to injury. His place was taken by Japan's Yuya Oshima.[2] [3] [4]
The singles and doubles tournaments consisted of knockout draws, with 16 players starting each of the singles events and eight pairs starting each of the doubles events. The seedings for the tournament draws were based on final tour standings, not the official ITTF world ranking.[1]
The 2018 ITTF Star Awards ceremony was held at the Grand Hyatt Hotel in Incheon on 12 December.[10]
