The uncapped Macs Page is one of eight Scarlets named in a 33-man Wales squad to travel to Japan this summer.
The 20-year-old Pembrokeshire speedster has enjoyed a breakthrough campaign, lighting up the URC with some stunning individual tries.
He is joined in the squad by fellow backs Blair Murray, Tom Rogers, Joe Roberts, Sam Costelow and Johnny Williams, who is recalled after an impressive run of performances.
Back-rowers, skipper Josh Macleod and Taine Plumtree are also named by interim head coach Matt Sherratt.
Hooker Dewi Lake will captain the 581-cap squad for the series.
Scarlets prop Henry Thomas needs to seek specialist opinion on a long-term condition, so won’t join the squad this summer.
A decision has been taken to give Adam Beard and Will Rowlands a break this summer, so they have not been selected in the squad, while Dafydd Jenkins is to have elective surgery.
Sherratt said: “I’m excited to get the players together in camp to begin preparations for our summer campaign. I think there’s a good blend of experience and young talent selected and that this group has a lot of potential.
“Going to Japan this July is a challenge the coaches and I are relishing. We are expecting a fierce contest from Japan in these Test matches.
“Over the next few weeks in camp, it’s about working hard, getting all our prep right on and off the pitch and gelling together as a group.”
Players will assemble in Wales camp on a staggered basis from Monday depending on when their club season ends, before the squad flies out to Japan at the end of June.
The two-Test series against the Brave Blossoms begins with Wales returning to Kitakyushu, the city that hosted the squad for a training camp ahead of the world cup in 2019, where the first Test takes place on 5 July at Mikuni World Stadium. Following that Wales head to Kobe for the second Test on July 12 at Noevir Stadium.
