Samoa head coach Stephen Betham has named his starting XV for the Pool B match against Japan at Stadiummk on Saturday.
Samoa have named their most-capped RWC team ever for the game, with a starting line-up boasting 346 caps.
The cap number beats the 316 total Samoa's starting XV had in their final pool match against South Africa at RWC 2011.
They have made five changes to the line-up that started the previous match against South Africa with Johnny Leota, Tusi Pisi, Fafili Levave, Kane Thompson and Ole Avei all named in the run-on team.
Leota makes his RWC debut, while Kane Thompson plays for the first time at RWC 2015 after serving a two-match ban for striking Australia's Saia Fainga'a in the 27-24 defeat by the Barbarians at London's Olympic stadium on September 2.
Thompson already has eight RWC appearances from 2007 and 2011.
