The Japanese sensation has one of the most amusing online presences in the sport, as her Twitter bio states: "I play tennis and make jokes that nobody ever gets."

Filled with ups and downs, Osaka's final year as a teenager was definitely an exciting one.

Let's just hope her next birthday ends up being more fun than this one.
