The nation’s community clubs had the honour of revealing the 31-man squad in an announcement video with each player’s nominated club revealing their selection.
Five props have been named in Nicky Smith, Wyn Jones, Rhys Carre, Tomas Francis and Dillon Lewis.
Ken Owens, who is heading to his third RWC, Elliot Dee and Ryan Elias are included as the three hookers in the squad.
Captain Alun Wyn Jones who has featured in three RWCs and played in 15 tournament matches is one of four second rows alongside Jake Ball, Adam Beard and Cory Hill.
Wales have named six back rows in James Davies, Ross Moriarty, Josh Navidi, Aaron Shingler, Justin Tipuric and Aaron Wainwright.
Gareth Davies, Aled Davies and Tomos Williams are named as the scrum-halfs with Dan Biggar and Rhys Patchell as the fly-halfs.
Jonathan Davies, Hadleigh Parkes and Owen Watkin feature as the centres in the squad with Josh Adams, Hallam Amos, Leigh Halfpenny, George North and Liam Williams included as the back-three selections.
“Selection is always the toughest part of the job and that is especially true come RWC time,” said Wales Head Coach Warren Gatland.
“Reducing the squad down to 31 has been extremely hard especially when you look at the depth we have created and the amount of the work the training squad have put in, for some, 14 weeks of training.
“We are really happy with the final 31, we feel there is an excellent blend to the squad, in terms of talent, experience and age profile and we are all incredibly excited about heading to Japan and what lies ahead.
“These players have performed and delivered for Wales and deserve the opportunity to represent their nation at the game’s showpiece tournament.”
