Wilson knows the short-term plan is for Wales to break the losing cycle and win a Test match for the first time since October 2023.
Wales travel to face Eddie Jones’ Japan in Kitakyushu on 5 July before the trip to play in Kobe seven days later.
“The group here are extremely passionate about turning around this run of games and results,” said Wilson.
“It is tough for some of those boys who have been involved in this long run of games and we collectively need to break that cycle.
“One win can change and breed confidence, sometimes that’s the bounce of a ball.
“Once you get on the right side of that, in this group there’s quality rugby players who will flourish.”
Wilson knows plenty about the challenges after being part of the Scotland set-up at the 2019 World Cup that were eliminated at the group stage after suffering a shock 28-21 defeat to Japan in Yokohama.
The afternoon kick-offs will provide challenges surrounding heat and humidity with Wales trying to get to grips with a greasy ball.
Wales prepared in 2019 by training with wet balls and sometimes using baby oil on them, with similar tactics being used six years on.
“There are big challenges around the humidity and cultural differences,” said Wilson.
“We did a huge amount of work on the humidity side of things and that is already being done.
“Greasy balls is an obvious challenge. I remember going out there and in the first few training sessions there were a lot of balls on the floor.”
