Takanashi was celebrating on Saturday, after victory in Romania's first ever ski jumping World Cup event saw her clinch this season's overall title.
The 17-year-old was pleased to bounce back from Winter Olympic disappointment last month, where she missed out on a medal, and she continued the recovery the next day.
Takanashi was in second place following the opening run, just 1.4 points behind Italian Evelyn Insam, but a huge leap second time around ensured she would not be caught.
She went 93.5m to pick up 123.2 points, 7.2 more than anyone else, on the second jump to ease to victory.
Insam finished third after a disappointing second jump of 103.7 points, with American Jessica Jerome capitalising to take second, 10.4 points behind the winner.
