After his first season in the Top League. Tanaka made his debut for Japan in May 2008 coming off the bench. He soon became a regular member of the Japan side and made the squad for the 2011 Rugby World Cup as first choice scrum half and is currently considered one of Japan's best and most important players.
In 2007 he played alongside former All Blacks fly half Tony Brown who was credited with helping him to develop immensely and Tanaka himself said Tony Brown is one of the most important influences on his career.
New Zealand Herald noted him as one of the most exciting players in the ITM Cup and was regarded as a hero for Otago and seen as their standout player.
He is my favourite player from the Otago Highlanders.
