Temperatures in Japan are expected to soar close to 40°C when Wales head out there next month for the opening match of their two-Test tour, with the opening match pencilled in for July 5 at Mikuni World Stadium in Kitakyushu.

In a bid to cope with the expected heat, Wales have gone through a series of stomach-turning training sessions at their Vale Resort base.

The squad has been doing gym work in a special chamber recently, where the heating has been turned up to over 38°C, leaving players exhausted and drenched in their own sweat.

Adams says many of the players have already been left close to breaking point, and says it's even tougher than the two-week training camp in Fiesch, which aimed to get the players up to speed with the increase in altitude ahead of the 2023 World Cup.

"I came out of the chamber on Friday and some boys were like, that's the hardest thing I've ever done and then I was like, it's got to be in the top three worst I've felt after a session," Adams said.
