TOKYO, 25 Oct - Winning his 50th England cap this weekend will be an occasion for Billy Vunipola to savour. But plenty of time for that later.
Right now, it is the opportunity to upset rugby's world order that is dominating his thoughts.
The big number eight, dogged by injury after injury in recent times, has absolute faith in coach Eddie Jones and his blueprint to beat New Zealand on Saturday.
Despite England losing six games in a row to the All Blacks, Vunipola, above, is confident the streak will end, thanks to Jones's impressive record against them with Australia (five wins in 11 matches).

"I don't think I have known a coach who has beaten New Zealand more times than Eddie," Vunipola said.
"He always knows how to do it. It might not happen consistently but he has the formula. Trust in Eddie and hopefully we can produce the performance.
"I don't know how to explain it. I haven't beaten them but it almost helps you by firing you up to try to change the course of history. And it's a World Cup semi-final."
Having recovered from three broken arms and other injuries, Vunipola, pictured below outmuscling Tonga, is understandably proud of hitting his international half century.
"Getting to 50 caps is a big mark but it isn't something I have put a lot of thought into yet. My focus has been on trying to help the team.
"From my point of view it was a journey I was on and I have tried to keep my head down. It was a case of getting over the injuries and trying to get back into the team. That has been driving me. It is part and parcel of the game to get injuries and I seemed to get them in one go, not one at a time."
Billy follows brother Mako Vunipola in winning his 50th cap, and both will have vital roles to play on Saturday. Mako expects the scrum to be key and is not convinced his experience as a member of the British and Lions squad that shared the test series with the All Blacks in 2017 is that relevant.
"Being part of a team that beat the All Blacks is the only thing you can take from it," he said. "They are a different team now from two years ago, with new players and a different way of playing. Saturday is a different scenario on the biggest stage of my career so far.
"The scrum kind of sets the tone for us as a forward pack. We want to be the best pack in the world. New Zealand are the best team in the world for a reason, and it all starts up front.
"We are under no illusion about what it will be like. We are very excited to get stuck into the challenge."
