Beppu - Wales coach Warren Gatland continues to keep the core of his top line-up together, making only two changes for Wednesday's Pool D match against Fiji in Oita.
Both changes in the run-on side are in the back row with Ross Moriarty and James Davies coming in at number eight and openside flanker, with Josh Navidi switching to the blindside.
The front five remain the same from Wales' opening two victories against Georgia and Australia.
Wyn Jones, Ken Owens and Tomas Francis pack down in the front row with Jake Ball and captain Alun Wyn Jones continuing their partnership in the second row.
The backline is unchanged with Gareth Davies and Dan Biggar, who failed a head injury assessment during the win against Australia on September 29, named as the halves.
Hadleigh Parkes and Jonathan Davies are paired in the midfield and Josh Adams, George North and Liam Williams line up as the back three.
Wales are on track to win Pool D and set up a quarter-final against the loser of next weekend's clash between England and France.
