Japan's try-scoring hero in their shock win over the Spingboks was an "explosive" schoolboy athlete in Hawke's Bay before he shifted south and became a "block-busting" winger.
Replacement back Karne Hesketh's extra-time touchdown has written the 30-year-old into rugby history.
He is part of a strong Kiwi contingent in the Japanese team, including captain Michael Leitch, Luke Thompson and Michael Broadhurst.
Fumiaki Tanaka plays for the Highlanders and Otago too.
Hesketh didn't start and Mr Brown said he would have viewed the entire game if he had.
"We're very proud of him [and] all these guys who do well on a world stage, but particularly in such a significant event for world rugby, that's probably why we're delighted.
"It's always great to see them playing and you knew them well as kids. I've been away on a prefects camp with Karne."
Hesketh was a strong all-round athlete and excelled at the high jump too.
"He's a chunky fella but he's powerful and very explosive," Mr Brown said.
"He was a very good flanker and you could imagine someone with his speed, power and agility. He really got around."
Hesketh headed to Dunedin for university and ended up playing for Otago from 2006 to 2010.
While studying he met his partner Carla Hohepa. Both played for the Alhambra-Union Rugby Football Club and Hohepa represented New Zealand.
Alhambra club captain Hugh Tait, who watched a replay of today's match, said Hesketh was part of a successful era for club, where they won the local competition a couple of times and regularly made the play-offs.
"When he was playing for us he was outstanding. He used to be a flanker. He came to us as a flanker but I think he realised he wasn't going to be big enough and he said he wanted to be a winger.
