For the 24-year-old from Perisher, Inawashiro marked his first World Cup final, improving on his previous best performance of 18th in Deer Valley this year.
Hall, on the comeback trail from injury, progressed to the 16-man final with the 10th best score in qualifying.
Unfortunately Hall’s first final score of 68.83 was not high enough to put him into the six-man super final, which was won by Canadian Mikael Kingsbury, and followed by American Brady Wilson and Olympic champion Alex Bilodeau from Canada.
In the dual mogul event at Inawashiro, Hall was unable to replicate his performance in the single moguls, finishing 26th.
