And McBryde is convinced lifting the Six Nations trophy for the fourth time in nine years will boost the spirits of those who played in the Championship and players new to the squad.
"The squad we take to Japan will head over there full of confidence and belief," said McBryde. "Players who played in the Championship will have the belief behind them but also players who maybe didn't feature will be boosted as success breeds success. It was a very accomplished performance on Saturday.
"We spoke during the week that it was just another test match that we had to go out and win and that's exactly what we did. We didn't focus on the points difference or the advantage they went into the match with, we were focused on the 80 minutes in front of us.
"The side went out and started well, controlled the early exchanges and took us into the break with a small cushion. In the second half we stepped it up and showed the sort of performance we all knew we were capable of and it was a fantastic way to win the Championship."
McBryde will announce his squad once the British & Irish Lions selections have been revealed this spring, with the former Wales hooker looked to blend experienced pros with younger players.
"For North America in 2009 we took a good mix of experience and youth and I'm sure that will be the case again this summer," he added. "It's a good chance to reward players with more international game time and give players the opportunity to play at this level.
"The Lions will obviously impact on selection but it will be taking experience out to Japan with us. We will also be looking to reward players who have performed for their regions week in and week out and who put their hand up towards the end of the season."
