Japan joined leading figures in tennis in rallying around Naomi Osaka on Tuesday after the world No. 2 withdrew from the French Open in a row about post-match media duties, saying she had been suffering from "depression" and "anxiety."

One of the biggest names in sport, Osaka stunned the tennis world when she pulled out of the Grand Slam on Monday after being fined and threatened with expulsion for declining to face the media after her first-round match on Sunday.

The four-time Grand Slam champion had last week signaled her intentions to skip her media duties to protect her mental well-being and she returned to Twitter on Monday to announce her withdrawal.
