Cardiff Blues lock Bradley Davies will captain Wales on their two-Test tour of Japan, which also sees the return of Steven Shingler.
Davies gets the nod from interim head coach Robin McBryde after impressing on his return to the side having overcome an ankle injury that ruled him out of their successful Six Nations title defence.
The 26-year-old has not played for his country since been knocked out by a punch from New Zealand hooker Andrew Hore during last autumn's Test series.
But Davies is fighting fit again and will get the opportunity to lead his country in the absence of the likes of Ryan Jones and Matthew Rees, who are rested.
Meanwhile, London Irish back Shingler is picked just over a year after he unsuccessfully attempted to represent Scotland.
There are nine uncapped players in the 27-man squad, which has been reduced from an initial training party of 32, including Ospreys centre Dafydd Howells and Blues fly-half Rhys Patchell.
The two hookers in the squad, Scarlets' Emyr Phillips and Scott Baldwin of the Ospreys, are also uncapped.
Scarlets hooker Ken Owens, fly-half Rhys Priestland and centre Scott Williams miss out though after they picked up injuries in the RaboDirect Pro12 semi-final defeat to Ulster, while Blues flanker Josh Navidi also misses out after being chosen in the initial touring party.
Dan Biggar is the only member of the side which beat England in the Six Nations title decider who makes it onto tour, with all 14 of his colleagues from that fixture touring Australia with the British and Irish Lions.
"We've had the training squad together for more than a week and we've been impressed," said McBryde.
"They have really put the effort in and stepped up as we have asked them to. Everyone in the training squad put their hand up for selection making our jobs much harder.
"It's a chance for these players now to experience the international Test environment and put their marker down."
Wales will take on Japan in Osaka on 8 June before facing them in Tokyo on 15 June.
