Japanese Golfer Ryo Ishikawa said compatriot Naomi Osaka had suffered a "tough time" and he understood her decision to skip news conferences at tennis's French Open.

Osaka withdrew from the French Open last month before the second round in the wake of controversy caused by her decision to skip some of her mandatory post-match media commitments.
