It marks an historic first association for Vans with the WSG, which will be held in Miyazaki between September 7 and 15. 

Places at next year's Tokyo 2020 Olympic Games, where surfing will debut, will be on offer to competitors.

"We welcome Vans as a partner to our event," said ISA President Fernando Aguerre.

"It's an amazing moment in the history of the ISA and the World Surfing Games.

"We are stoked that Vans has understood and embraced the unique value of this year's historic edition as a qualifying event for the Tokyo 2020 Olympic Games.

"Vans has a rich and vibrant history in the sport of surfing and we can't wait to celebrate with them this momentous occasion."

Bobby Gascon, Vans' global director of action sports, added: "This is an exciting time for surfing worldwide, and Vans salutes ISA for championing diversity as part of their global vision.

"We're excited to support the world's surfing elite in their Olympic pursuits and look forward to partnering with the ISA in furthering the momentum of surfing culture on the world stage and beyond."

This year's WSG will be headlined by World Surf League champions Stephanie Gilmore from Australia, Brazilian Gabriel Medina and United States star Carissa Moore.

Strong showings are also expected from WSG champions Sally Fitzgibbons from Australia, France's Jeremy Flores and American Courtney Conlogue.

Slots at next year's Olympic Games are up for grabs at the WSG for the top finishing eligible men and women from Asia, Africa, Europe and Oceania.

The Americas' qualification slots will be determined at the Lima Pan American Games this week, with the surfing competition running from yesterday (July 29) through to Sunday (August 4).

Event branding for the WSG will be designed by world-renowned Japanese artist Yusuke Hanai and there will be a two-day Surf Festival during the opening weekend of the event to showcase the culture, food, music and lifestyle of surfing in Japan. 

Japanese musicians Def Tech and HIRAIDAI will perform during the festival.
