Wallabies back-rower Rob Valetini is crediting a timely refresh for his barnstorming Test form, out to continue it in Japan.
Valetini and the Wallabies resume their Test campaign in the heat of Osaka, facing Japan to start a two-Test series.

It comes after the Brumbies Player of the Year was one of Australia's best during the Nations Championship.
Valetini was the Wallabies' top tackle-buster in the three-Test series alongside Joseph-Aukuso Suaalii, recording 14 defenders beaten in four matches.
Only Harry Wilson (35) made more carries than Valetini (35), with the 27-year-old feeling refreshed after the Brumbies' early exit.
"I carried a few niggles during Super, so going into the Wallabies I've been feeling better," Valetini said to reporters.
"I've been able to focus on my role more at Wallabies will a bit more certainty out in the wider channels or running hard balls off the centres.
"I think it's been all about my mindset and I got that good break and refresh."
Valetini monstered Italy late to cap off a perfect performance in Perth, bulldozing several defenders before Ben Donaldson's try.
The expansive style and the fitness of the Wallabies will be tested on the weekend during the oppressive conditions in Osaka, with the group using saunas and whatever else at their disposal to get used to the heat.
"We know that they want to play fast, and obviously it's quite hot here. We think they'll try to use that to their game plan and try to run us off our feet," Valetini notes.
"It'll be important for us to adapt to the weather here, and we have been doing that with our saunas daily and our training so hopefully we're prepared well for the weekend."
The back-rower and the squad are looking to express themselves under new coach Les Kiss, believing it'll bring the best out of their star back-row trio.
"I think he wants us to use our strengths and skill sets, whilst working on your weaknesses throughout the week to try and get better," he explained.
"I think with some like 'Wilso' [Harry Wilson] who can offload and free up his hands, get the ball wide, there's a bit more freedom within that."
