The 16-year-old backed his aggressive backhand throughout the contest and went on to win 17 of his 23 points at the net to seal victory in 61 minutes.
Mochizuki became Japan's only second Grand Slam junior champion, following the footsteps of Kazuko Sawamatsu, who captured the Wimbledon and French Open girls' titles in 1969.
Having began playing tennis at the age of three, Mochizuki has fine-tuned his game under coach Natsuo Yamanaka at IMG's tennis academy in Bradenton, Florida, where Japan's current number one Kei Nishikori also honed his game.
