Japan's new elite rugby union competition will kick off its inaugural season Saturday with the lofty goal of becoming the "best league in the world."

Superseding the more corporate-oriented Top League, the newly minted Japan Rugby League One aims to recruit the world's top players and build upon the enthusiasm generated by Japan's successful hosting of the 2019 World Cup, its chairman Genichi Tamatsuka said.

Outlining these ambitions at a recent media conference, Tamatsuka, a former university rugby player and the current president of Lotte Holdings Co., said the World Cup provided a glimpse of the sport's massive potential in Japan.

"All of Japan was caught up in the rugby. I felt an unbelievable sense of possibility," Tamatsuka said.

The curtain raiser was to be held on Friday, but was canceled after six players from one team tested positive for the coronavirus.

Some of the sport's biggest names are already set to play in JRLO, continuing the recent trend of world-class players joining big-spending Japanese clubs.

Toyota Verblitz scored a coup by signing 2019 World Rugby Player of the Year, South Africa loose forward Pieter-Steph du Toit. He will play alongside New Zealand lock Patrick Tuipulotu, while another All Black, back Damien McKenzie, has joined Tokyo Suntory Sungoliath.

NTT Communications Shining Arcs Tokyo-Bay Urayasu, meanwhile, added controversial former Wallabies star Israel Folau, a record three-time winner of the John Eales medal for Australia's best player.

To increase the overall quality and competitiveness of matches, JRLO has trimmed its first division down from Top League's 16 teams to 12 divided into two conferences.

Despite the push for professionalism, clubs remain dependent on the backing of their parent corporations, with squads still combining fully professional players and others who are company employees.

Tamatsuka, however, says this "unique hybrid system" is an advantage for the league, which draws financial and marketing clout from some of Japan's biggest corporations.

JRLO plans to emulate soccer's J-League in fostering loyal local support bases and requires clubs to have a city in their team name. This has resulted in several monikers including "Tokyo," reflecting the concentration of corporate headquarters in the capital.

Toshiba Brave Lupus Tokyo, featuring Japan back rower Michael Leitch, will aim for their first trophy since capturing their fifth Top League championship in 2009-10.

"The team is confident. Our goal is to win the title," said Leitch, who captained Japan to the World Cup quarterfinals in 2019.

"Our style is to play boldly without hesitating. When we have the ball, we'll look to simply carry it forward."

Last season's Top League champions, Saitama Panasonic Wild Knights, were to face Kubota Spears Funabashi Tokyo Bay at Tokyo's National Stadium on Friday night but six infections within the Wild Knights forced a postponement.

At a preseason press conference, Saitama captain Atsushi Sakate said the Wild Knights want to start the new era with another trophy.

"We're aiming to win the first (JRLO) championship," the Brave Blossoms hooker said.

Instead of its planned Friday opening, the league will kick off with three games slated for Saturday, including Sungoliath vs Brave Lupus at Ajinomoto Stadium, with the remaining two opening-round fixtures set for Sunday.
