The two events "will work closely together" Tokumasu promised at the Sport Events Management Conference

Tokumasu told insidethegames that the fact Japan is hosting two of the world's biggest events so closely together is a positive for rugby's showpiece event in 2019.

"Because of the 2020 Olympics then [the profile of sport] in the country will be automatically raised to [a new level] and because the Rugby World Cup will be staged in 10 or 12 venues across the country as well as various training camps that will be hosted across around 30 cities then we can [capitalise] on that interest also," saidTokumasu.

"The Rugby World Cup 2019 Organising Committee will work closely with the Tokyo 2020 Organising Committee.

"As long as we have good communication then we can do something together.

"The two events have to look at each other very closely and see what we can do separately and what we can do together."

Tokumasu, who claims he fell in love with the sport when he saw former Wales and British and Irish Lions star Gareth Edwards playing in Japan on a tour in 1975, is part of an Organising Committee that also includes Tsunekazu Takeda., President of the Japanese Olympic Committee (JOC) who led the successful Tokyo 2020 bid.

But Tokumasu revealed the two Organising Committee's have yet to sit down and discuss possible ways of working together but will do soon.

Japanese Olympic Committee President and head of Tokyo 2020 Tsunekazu Takeda is also a member of the Rugby World Cup 2019 Organising Committee
