Naomi Osaka has a certain comfort level when playing in Japan, something the former world No. 1 hopes to use to her advantage during the Toray Pan Pacific Open this week.

She has a good track record at the tournament — with one title and three appearances in the final — and the tennis star hopes the good vibes can help carry her to another triumph.

"I feel like I just want to play well," Osaka said at Ariake Coliseum on Monday afternoon. "I think that's always a really good feeling for me. Whenever I come to Japan, I feel really happy, I feel like I always play well here, and I think I do. So I think it's a really good combination."
