British number one and eighth seed Laura Robson saw off Greece's Eleni Daniilidou 6-4 6-2 to reach the second round of the HP Open in Osaka.
Robson, seeded in a WTA tournament for the first time, appeared to be letting her opponent back into the match when Daniilidou came back from 3-0 down in the second set to the brink of levelling at 3-3.
But Robson held a tough service game, re-established her double break at 5-2 and served out at the first attempt to join compatriot Heather Watson in the second round, where she will face either Japan's Kurumi Nara or Zhou Yimiao of China.
