Courtney Lawes has promised England will give their all in pursuit of winning the World Cup.
Eddie Jones' men launch their bid to wrestle the Webb Ellis Trophy from New Zealand when they clash with Tonga at the Sapporo Dome on Sunday, the first of two games they must play in four days.
Arriving in Japan as joint-second favourites alongside South Africa and behind the All Blacks, they have the goal of atoning for their embarrassing performance at the last World Cup.
"We can't be more committed to winning the tournament. We've given everything over the last four years that we could to prepare for it," Lawes said.
It is one of only two changes made to the team that overwhelmed Ireland at Twickenham last month with Anthony Watson's selection ahead of Joe Cokanasiga on the right wing the other.
"I'm delighted to have a start and I want to get out there and put it all on the pitch," said Northampton lock Lawes, who is appearing in his third World Cup.
"Eddie wants physicality from me. I've got a lot of experience so he wants me to help lead the team in my actions.
"Although on paper we are a young team, we are still an experienced team with cool heads throughout and so we have a good chance of going far."
