Assistant coach Shaun Edwards says a narrow victory over Japan on Saturday was a "tremendous" achievement for a young Welsh side.
Wales, led by Robin McBryde this summer and missing rafts of players to the Lions tour of Australia, came through 22-18.
"A lot of the lads in the team hadn't played a lot of Test match rugby and hadn't played in a number of weeks, and factor in the heat and humidity, it was a good result."
"We got on with the job, showed a lot more fluidity in the second half. We battled it out and we have a lot to be proud of."

Wales head coach Rob Howley admitted his side's performance 'simply wasn't good enough' against Scotland this afternoon.
It will be cloudy with outbreaks of rain at first, but most of the rain will clear by morning.
Despite leading at half time, Howley's men failed to score in the second half with Scotland racking up 20 points to seal the win.
