Wales Under 20 head coach Phil Davies has brought five uncapped players into his 22 for a development game against Japan at Aberavon (Wednesday, 7.10pm).
Carmarthen Quins threequarters Jamie Davies and Jason Harris have been brought into Davies' training squad and named in the starting line-up, while Glamorgan Wanderers scrum half Lloyd Williams, Llandovery prop Owen Evans and Scarlets academy full back Daniel Newton will start on the bench.
Japan are set to host the second Junior World Championship in June and are currently half way through a four-match tour of Wales in preparation for that tournament. Davies too, will use this game to help build his squad for the Junior World Championship.
He said: "This will be a very useful exercise. It will help us to keep our momentum going after the Six Nations Championship, and gives some players a chance to work their way into contention for the Junior World Championship squad.
"All five of the uncapped players have trained with us at some point during the Six Nations Championship and this match, with injuries to a number of our Six Nations three quarters, gives them an opportunity to prove themselves at this level."
Japan have played Welsh Academicals and UWIC since arriving in Wales and will play a North Wales Under 20 XV at Swansea RFC on Saturday.
