Jelena Jankovic said it was more like the Japanese Open than the Australian Open Saturday after beating her third opponent from the Asian nation to reach the last 16.
The former world number one knocked out Kurumi Nara in straight sets after wins against Misaki Doi and Ayumi Morita in the first and second rounds.
"I'm playing the Japanese Open, it's not the Australian Open for me!" she said. "Of course, I'm not going to get a visa for Japan next time I want to go.
"I look forward to playing some other people from somewhere else next round."
Serbia's Jankovic, 28, will play Simona Halep from Romania for a place in the quarter-finals. All four Japanese contenders are out of the women's competition -- with Jankovic accounting for all but one of them.
