Among the legions of supporters to descend on Japan are a host of proud parents, partners, siblings and cousins following the fortunes of Fiji, Tonga and Samoa.
Saki Waikere made the trip from Suva to Sapporo with some friends to watch his cousin Leone Nakarawa play in Fiji's World Cup opener against Australia.
"We're here to support him and definitely we're coming for a win so we're looking forward to that and I know it's going to be a good game," he said.
"Even though (against) Australia we are playing as underdogs today so definitely we will catch up to them."
