Captain Alun Wyn Jones will equal Gethin Jenkins' Wales cap record when he leads out his side against Georgia in Toyota City.
Jones, 34, will win his 129th Wales Test cap on Monday as he starts his fourth World Cup.
Flanker Aaron Wainwright and prop Wyn Jones start ahead of Ross Moriarty and Nicky Smith.
Josh Navidi is named at number eight with Justin Tipuric completing the back-row.
Head coach Warren Gatland has chosen his strongest side for the tournament opener.
Prop Jones is picked ahead of Smith at loose-head in a front-row that also includes Tomas Francis and hooker Ken Owens who makes his first World Cup start in his third tournament.
"With Georgia, we know how strong they are up front and their scrum is a weapon," said Gatland.
"We've got to be competent at scrum time, We've been very impressed with the way Wyn has scrummaged in training and it's one of his strengths.
"It's important for us and it's been a real focus for us, particularly this week."

With locks Cory Hill and Adam Beard missing the first game through injury, Jake Ball partners captain Jones in the second-row with Aaron Shingler covering the position among the replacements bench.
Dragons flanker Wainwright has been chosen at blindside with Josh Navidi preferred at number eight to Moriarty and Justin Tipuric completing the back-row.
The 24-year-old from Newport has impressed Gatland.
"Aaron Wainwright is just a player that's continued to improve," he said.
"He's incredibly athletic and an intelligent rugby player. He's very inexperienced still but I think there's only an upward curve for him as a player.
"I don't think people realise how quick he is and how explosive he is.
"Since his first cap 12 months ago, he's just gone from strength to strength.
"There's some real competition in the back row and that's the way we want it. We feel there's a nice balance."
Gatland revealed Moriarty's disappointment at not starting against Georgia.
"He hasn't been where he has needed to be in a couple of games and at training," said Gatland.
"There are a few things for him to work on. He's a fantastic ball carrier and there were some things we worked on defensively in terms of changing his tackle technique.
"He's not too happy with me with him not being in the side, but from the initial disappointment and chat we had, he's turned that around.
"I'm interested to see what his reaction will be when he comes on the field."
Scrum-half Gareth Davies partners Dan Biggar at half-back with fly-half Rhys Patchell fit to take his place on the replacements bench after suffering a head injury in the final warm-up game against Ireland.
Scarlets centres Jonathan Davies and Hadleigh Parkes again link up in the Welsh midfield alongside full-back Liam Williams and wings George North and Josh Adams.
This selection follows a testing week which has seen backs coach Rob Howley sent home for an alleged betting breach.
It will be a first game for new backs coach Stephen Jones who has arrived in Japan to replace Howley and will only have a couple of training sessions with the players.
"Stephen has been really good in getting up to speed," said Gatland.
"He's come in and sat down with the analysts, myself, Dan Biggar and Jonathan Davies.
"Yesterday we had a day off and he spent all day in the team room looking at game footage, going through training and the calls and everything.
"He took a full part in training today. Earlier in the week the players took a lot of responsibility, as you'd want them to.
"Stephen has started to have a good look at Australia. He'll have much more of an input into things and the plan that we put in place for that game.
"It's been easy because he's been in this environment as a player, he knows so many of the players as well.
"One of the things about Stephen is he's a very popular and amicable person and it's been good how he's fitted in so quickly in the first few days."
With an average age of 28 years 331 days Gatland's selection is the oldest Wales starting 15 at the Rugby World Cup - 80 days per man older than the team which beat Japan 72-18 at the 2007 tournament.
