Some of those changes have come about by the withdrawal through injury of Fiach O'Loughlin (Shannon) and Peter O'Brien (UCC), but this game against Japan affords coach Michael Bradley the opportunity to use his full squad of players.
Fiach O'Loughlin's replacement Daragh Geraghty, is named in the replacements. O'Brien is replaced by Denis Fogarty (CorkConstitution).
