"We have chances to win the championship every year and that is highly appealing to me and is one of the main reasons I have stayed there so long. Being able to play with good players week in and week out is the key. I didn't go over to Japan just for a retirement fund. I am competitive and I want to win."
Nicholas left Tauranga in 1998 to attend the University of Otago and made his provincial debut for Otago as a teenager in 1998. By 2001, he was a key Otago player and earned a Highlanders contract for the 2002 Super 12. He had an outstanding debut season, starting all 12 games and leading the side with seven tries.
But injuries and loss of form meant limited opportunities in following seasons, so he jumped at the opportunity to join Suntory and three years later he was making his test debut for Japan.
Nicholas played most of his test rugby under the coaching of John Kirwan, including the career high of playing back in New Zealand at the 2011 Rugby World Cup.
"I thrived under JK. He understands Japanese rugby and he brings his passion and his particular spin on the way we play.
"I think he has been great and progressively the team got more competitive under him and better and better every year.
"I've got big raps on JK and have total respect for him. He is just one of those guys who is really likeable and dedicated - you just want to follow him."
Nicholas has two more years to run on his Suntory contract and will consider after that what the future holds.
But there is a good chance it will be back in New Zealand.
He has a double degree to fall back on in sports science and management, so will consider options such as a trainer's role or business management.
