The Yokohama Keio Challenger International Tennis Tournament 2025 supported by Mita Kosan, in which Kei Nishikori will return to competition for the first time in about three months, will kick off on November 17th at Keio University's Hiyoshi Campus (Kohoku Ward, Yokohama). On the 14th, WOWOW announced that it would be live streaming Nishikori's matches on WOWOW On Demand.
Nishikori withdrew from the second round of the ATP250 Geneva Tournament in May this year due to back pain, and has since been absent from the tour. He returned to action at the ATP Masters 1000 Cincinnati Tournament in August, but lost in the first round. This will be his first return in about three months.
This will also be his second time competing in a challenger tournament held in Japan, 19 years after the Shimazu All Japan Indoor Tennis Championships in 2006.
