Marking 200 days to go until the tournament kicks off, World Rugby and ChildFund, the main charity partner for the event, have confirmed that a record US$2 million has been pledged to ChildFund Pass It Back.
ChildFund aims to instil values associated with rugbyand the programme will teach more than 25,000 children -- half of them girls -- leadership and conflict resolution.
"Rugby is a sport that embraces different shapes and sizes and therefore that spirit of solidarity feeds into such a programme," Gosper told AFP.
"The values of our sport are understood by people before they get to grips with the rules of it.
"Our values are ideal for things such as leadership skills, confidence, gender equality, management of a community, working together to achieve goals."
Gosper, who is hoping to visit one of the programmes, in Laos, in the next couple of months, said he is delighted with the money raised so far.
"Part of any major sports programme is what will be an uptick in the area," he said. "We hope the people involved will pass on the message to the village and that it resonates with those who have not been part of it."
And Gosper believes the message it conveys will have a long-lasting impact.
"The charity link-up was ideal as it is geographically aligned," he said.
"The benefits of the collaboration are enormous as it is a truly transformational and tangible legacy for the sport, but also society in Asia, which is one of the reasons we awarded the Rugby World Cup to Japan."
