As well as Mr Yokoyama, several other employees had not received the training required to drive the forklift.
During the sentencing, Judge Davidson said it was clear the level of training at TFL was a "significant departure from the industry standard".
WorkSafe chief inspector, Keith Stewart, said it was vital that workers operating heavy machinery had correct training and safety management systems.
"Sadly, in this instance, Mr Yokoyama has paid the ultimate price for the company's failure to meet these requirements," Mr Stewart said.
The company was fined $52,000 and the family of Mr Yokoyama will receive $76,994 in court ordered reparation.
