Cibulkova and Wozniacki answered questions from the young fans…

…as well as taught them a thing or two on the tennis court!

We challenged Agnieszka Radwanska to show off her origami skills – and of course she made herself a trophy!

The No.2 seed talked to the media during All Access Hour…

…and signed lots of autographs.

Someone else who signed lots of autographs was Naomi Osaka – known as “Nao-chi” to her delighted Japanese fans.

Spain’s Carla Suárez Navarro manned the autograph booth for a bit…

…and of course, she kept signing autographs for her many fans even after she was done.

Japanese fan favorite Nao Hibino is enjoying her time on home soil.

Toray’s top seeds and biggest stars – Caroline Wozniacki, Petra Kvitova and Garbiñe Muguruza – held a Q&A session at the Fan Zone.

Monica Puig, Puerto Rico’s trailblazing gold medalist, was back to her winning ways in Japan.

Top seed Muguruza and Wozniacki left the tournament a memento and signed the autograph board at Toray.

During a rain delay, Radwanska, Puig and Australia’s Jessica Moore donned kimonos and played a round of hanetsuki.

Hanetsuki is a traditional Japanese game similar to badminton (but minus the net). Usually played by girls on New Year’s, players who lose a point get a mark on their forehead – like Puig and Moore!

Now the players are ready to take to the court at Toray!
