One of the many fan activities away from the match courts so far in Tokyo have been kids clinics.
Like this one - Belinda Bencic and Ana Ivanovic had a Yonex clinic with 60 kids from the Fukushima area.
And this one, a Wilson clinic with Petra Kvitova, Victoria Azarenka, Sorana Cirstea and Simona Halep.
Former No.2 Kvitova, current No.2 Azarenka and Romania's Top 2 posed for a group picture with the kids.

A slew of WTA stars took center court for the opening ceremony of the 30th Toray Pan Pacific Open.
Kimiko Date-Krumm was interviewed by Ai Sugiyama on court - the only two Japanese to reach the Top 10.
Date-Krumm, who has been as high as No.4 in the world before, is fresh off the quarters in Seoul.
The Toray Pan Pacific Open began back in 1984 - its first champion was Manuela Maleeva-Fragnière.
Victoria Azarenka, the No.1 seed at this year's edition, met the press at Monday's All-Access Hour.
Another one of the exciting activities around the grounds took place at the Jetstar booth...
Star jumps - and photos of them - with Jetstar mascot Jetta-kun was a hit with players and fans alike.
Jetstar, an Australian-based airline, is the WTA's official airline partner in the Asia-Pacific.
Roberta Vinci, Petra Kvitova and Angelique Kerber were among the WTA stars hitting the Jetstar booth.
All three played their opening matches on Monday - the rest of the Top 8 seeds do the same on Tuesday.
