The defending champions take on Kenya in pool play today and Australia and New Zealand tomorrow.
Coach Gareth Baber said Fiji had been training away from the limelight of central Hong Kong but were now hoping to be energised by their supporters.
"We deliberately went and stayed out of Hong Kong because of how busy it is. We needed to gain focus," Baber said.
"I haven't seen a huge amount of supporters yet. I know that come Friday and Saturday that will be a different case," he said.
