Career
He also plays for Top 14 side the Panasonic Wild Knights in his home country. Yamada has been a prolific try-scorer for the Wild Knights in Japan"s Top 14 competition since making his debut during the 2010-2011 season. He enjoyed a stand-out year in 2012-2013 scoring 20 tries in 14 games to be the league"s top scorer.
Ahead of the admission of a Japanese franchise into Super Rugby, Australian sides were permitted to contract one Japanese player per season to aid their development.
And so it was that the Perth-based Western Force signed Yamada to a one-year contract ahead of the 2015 Super Rugby season. Yamada made his debut for Japan on 15 November 2013 in a 40-13 victory over Russia in Colwyn Bay, Wales.
To date he has scored 8 tries in 10 international matches.
