Osaka still set to play Wimbledon, say organisers
The 23-year-old four-time Grand Slam winner said following her withdrawal from the French Open that she was taking some time out of the game as she battles depression and anxiety.
However, on Wednesday All England Club chief executive Sally Bolton said as things stood Osaka would be at the championships, which get under way on June 28.
"We've reached out to her team, we haven't spoken to Naomi herself," said Bolton. "At this point in time she's entered into the championships and we haven't received confirmation that she won't compete."
Tournament director Jamie Baker said he had told Osaka's entourage that the phone lines were always open to discuss any issues that might arise.
"I had the conversation with her team," said Baker.
"It's absolutely clear that we're here, we're completely open for any discussions when they want to have that. Hopefully it goes without saying that we want the best players competing here no matter what."
World number two Osaka has been in the spotlight since withdrawing from the French Open.
She was fined $15,000 and threatened with disqualification from Roland Garros after she refused to honour mandatory media commitments.
French Open organisers protested that they had treated her with "care and respect" after they were accused of being heavy-handed.
