Wales wing Liam Williams believes that the young squad of players would have learned from their narrow victory over Japan on Saturday.

The 22-year-old, who was part of the side that trailed 11-6 at the interval, has also vowed that the team will improve in the remainder of the tour.

"We are a fairly young squad with a number of new caps making their first appearance at this level. To come up against Japan without that many games as a team was tough, but the boys pulled through in the end," he told Press Association Sport.

"You learn more from hard games like that when you're under pressure, away from home and playing those conditions than a 60-point win. That experience will stand everyone in good stead.

"But we know we need to improve all aspects of the game. There were a couple of areas we didn't play too well and, once we have sat down and examined the video, we'll take it from there."

Williams has won four caps for his country.
