France kicked on in the second half to defeat Japan 47-7 at the U20 World Championship in Parma.
Tighthead prop Quentin Bethune grabbed the opening try when France attacked off the lineout and he was followed over by his tight-five colleague Julien Delannoy, with fly-half Anthony Belleau knocking over both conversions to give France a 14-0 lead.
Japan however rallied, just as they did against England on Tuesday, and forced France down to 14 men when prop Quentin Walcker was sin-binned for multiple scrum infringements.
Not long after Japan were awarded a penalty try for their first points of the match thanks to their scrum, with France leading 14-7 at half-time.
Scrum-half Gauthier Doubrère struck early at the start of the second half to ease the pressure on the French who grew in confidence.
Judicaël Cancoriet and replacement Camille Chat scored two quick tries, both converted by replacement Lucas Meret, with centre Pierre Fouyssac following them over shortly after as France cruised home.
Lucas Bachelier's yellow card left them down to 14 men in the close minutes, but the job was done as Fouyssac grabbed a late second score for it to finish 47-7.
