Pool D captains, including Wales's Scott Andrews, at the Tokyo launch ahead of the tournament kick-off.
Ospreys academy and Aberavon back row Justin Tipuric will lead Wales Under 20 in their opening match of the IRB Junior World Championship, against Tonga in Saga tomorrow (Friday, 11am UK time).
Three players will earn their first Wales Under 20 caps in this game with uncapped trio Llanelli of full-back Daniel Newton, Carmarthen Quins centre Jason Harries and Glamorgan Wanderers scrum-half Lloyd Williams all earning their places in the starting line-up.
Two other uncapped players, Owen Evans of Llandovery and Jamie Davies of Carmarthen Quins, start on the bench.
Squad captain Scott Andrews, Dragons academy outside-half Dai Langdon and Cross Keys scrum half / wing James Leadbeater are unavailable for this game with minor injuries but should all be available for Wales' second game of the championship against Canada on Tuesday. Ospreys academy no 8 Rory Pitman goes straight into the starting line-up after joining up with the squad from New Zealand where he has been playing with Air New Zealand Cup side Taranaki
Wales head coach Phil Davies said, "The boys have worked extremely hard since we arrived in Japan at the end of last week. The new caps have all performed well in training and deserve their opportunity on the field tomorrow. We are confident in these players and hopeful this team will bring us a winning start to the tournament. However, we have five games over 16 days and therefore a 26-man effort is undoubtedly required in order to do well for Wales in this campaign. Rory (Pitman) is in great shape, he has trained well and fitted straight back into the group well, there is no doubt his time in New Zealand has helped him.
"Being in Japan is providing a new cultural experience for the players, alongside the rugby experience. We visited the Atomic Bomb Museum in Nagasaki this week, an unbelievable experience for the players and management."
