Hirayama has been a mainstay for Canada Sevens since making his series debut in 2006 at the age of 18. Since then he has built a global reputation as one the top playmakers in the game. Hirayama was one of the standout players in 2012/13 as he racked up the third most points on the series with 241. He went on to top the points list at the 2013 Rugby World Cup Sevens in Moscow as his excellent performances that campaign earned him the captaincy in 2013-14.

However, an injury plagued season led to Hirayama missing five of the nine tournaments, which meant he could not repeat or better the outstanding showings he displayed the previous
year. Injury again hampered his 2014-15 season as he featured in only the final two tournaments of the series. Hirayama was a member of Canada’s 2015 gold winning Pan-Am Games
team and won gold with the team in 2011 too.

In the fifteen-man game, Hirayama has been part of the last three Rugby World Cups for his country and was outstanding in the 2015 tournament, playing a high quality game at flyhalf
as Canada impressed with their slick style. He has scored 47 test points in 23 games.
