Sympathy for Osaka in Japan over French Open withdrawal
The four-time Grand Slam winner's career is followed closely in Japan and the controversy in Paris, which followed her refusal to attend press conferences, led news bulletins on Tuesday.
"I hope she gets to eat what she wants, watch what she wants and listen to what she wants. I hope she wraps herself up in a fluffy blanket and takes it easy until she feels content."
Her withdrawal follows the fall-out from her decision to boycott press conferences at the tournament, which she said were like "kicking people when they are down".
But Japanese fans urged her to take care of herself first and foremost.
"I dare say she might withdraw from the Tokyo Olympics," wrote one Twitter user.
"It's disappointing, but I hope she takes her time and gets well."
"There's a big difference between people's personalities, and I think we need to consider things on a case-by-case basis," said Sugiyama, who reached a career-high number eight world ranking.
"I think the system where you absolutely have to turn up and you're fined if you don't is a little out-dated."
Some Twitter users questioned whether Osaka was feeling the strain of competing for titles and speaking out against racial injustice.
"Naomi Osaka is fighting -- against herself, against pressure, against fixed ideas, against discrimination," tweeted TV presenter Ruriko Kojima.
"All these things surely cause her anguish. I just can't imagine the pressure she carries on her shoulders. It's such a different perspective. I hope she gets some time where she can laugh and relax."
