Water breaks and longer half-time for Wales in Japan
Wales and Japan will be given water breaks and an extended half-time period to help the two sides deal with the heat and humidity in Kitakyushu on Saturday.The match is being played at 14:00 local time with temperatures expected to reach 33C, while there will also be a high level of humidity.There will be a three-minute break midway through each half, while half-time will be extended to 20 minutes.The measures are being taken under World Rugby's updated heat and air quality guidelines, which set out the measures to be taken to support players playing in hot conditions. The half-time extension is the second most severe reading with the next step being to consider "delaying or suspending the game".
How hot is too hot for World Rugby?
The guidelines cover whether water breaks should be introduced, as well as measures such as extending the half-time break or if a game needs to be suspended.Written by Dr Grant Lynch and Dr Olly Jay of the University of Sydney, the guidelines focus on a heat stress index rather than just basic air temperature. The index runs between 0 and 250 with levels of heat stress determining what action will be taken.World Rugby uses a number of devices which measure all the elements which go into calculating the heat stress Index, including air temperature, humidity, wind speed and ground radiation. The readings are then put into the following categories:Low (0-99 heat stress index) – teams follow standard practiceModerate (100 to 149) – players take on more fluids and reduce the amount of clothing wornHigh (150 to 199) – players to have a three-minute cooling break in each half. Team also to implement cooling strategies such as iced towelsVery High (200 to 249) – half-time extended to 20 minutesExtreme (250+) – consider delaying or suspending the game.In the extreme case of a game being suspended, the guidelines also set out exactly the conditions that need to be met for a game to begin or resume:The heat stress index must fall below 230 and remain below that level for 45 minutesWeather forecasts indicate a low risk of the heat stress Index rising above 250 for the next two hours if the game has started or three hours if it has not yet begunThe match-day doctor is happy it is safe to play.
Preparations for heat and humidity
Wales have turned to ice towels and freezing flannel hats to combat the extreme conditions on this trip.The thermometer has hovered around the 33C mark since the Wales squad touched down in Japan last Thursday for the two-Test series against the Brave Blossoms.The draining humidity means the temperatures feel much hotter for Wales' players, who had eight ice baths at the side of the pitch during Tuesday's training session.Each player in the 33-strong squad was required to spend a minimum of five minutes in an ice bath and 500 kilos of ice was used in the session.Before Wales arrived in Japan, they prepared in a specially designated heat chamber at their Vale of Glamorgan training base, where they performed extensive exercises in extreme conditions.Japan coach Eddie Jones says whoever deals with the conditions better will win the game and has previously commented he hopes for a hot day as the hosts try to "run Wales off their feet".

Further despair as Wales feel the heat in Japan
Summer tour second Test: Japan v WalesVenue: Noevir (Misaki Park) Stadium, Kobe Date: Saturday, 12 July Kick-off: 06:50 BSTCoverage: Watch live on S4C and BBC iPlayer; listen live on BBC Radio Wales, BBC Radio Cymru & BBC Sounds; text commentary and highlights on BBC Sport website and app. Wales revealed their devastation at wilting in the Kitakyushu heat to lose 24-19 to Japan and suffer a record 18th successive Test tries from Ben Thomas and Tom Rogers, as well as a penalty try, gave Wales a 19-7 half-time lead and hopes of a first victory since beating Georgia at the 2023 World Cup in October Japan dominated the second half as Wales suffered in the extreme heat and from Takuro Matsunaga, Ichigo Nakakusu and Halatoa Vailea, plus nine points from the boot of Seungsin Lee, piled on more misery for captain Dewi Lake was close to tears after the final whistle with Wales' 21-month wait for an international victory continuing."I don't want to speak for everyone but we are gutted," said Lake."It's very tough to take because we have worked hard. "We take nothing away from Japan for the way they played and coming out on top, but we had moments to win that game and put it to bed." Wales interim head coach Matt Sherratt says the whole squad had been affected."You could see the feelings not just from the squad but the whole staff as well," said Sherratt."They are a very passionate group. We had a lead going into half-time so to lose the game at the end is very disappointing." Wales slump to new low The defeat means Wales have again slumped to a new all-time low as they are still searching for a first Test win in 21 months. Wales have slipped two places to a lowest place ever of 14th in the world rankings, now below Japan and says Wales can not feel sorry for themselves with the second Test in Kobe next Saturday."Already we have got to quickly use the hurt to fuel us for next week," said Sherratt."The great thing about this tour is we get the chance to put it right."Japan head coach Eddie Jones warned Wales they will face an improved side next weekend."We're really happy with the win," said Jones."We will enjoy it and get ready to go again in Kobe, where we'll need to play much better than today."Sherratt confirmed Wales lock Ben Carter will miss that game after he took a heavy hit to the side of the head after just 34 slumped to the ground after attempting to make a tackle and there was a lengthy stoppage before the second row was taken away on a Dragons captain was up and about in the changing room afterwards but will not be available next weekend. Wales not blaming the conditions The oppressive conditions - with the temperature above 30 degrees Celsius as well as high humidity - meant a three-minute water break in each half and an extended interval of 20 minutes were faded badly in the second half as Japan scored 19 unanswered points but Sherratt refused to blame the heat and humidity for the tourists' demise."I would be making excuses if I said that [conditions played a part]," said Sherratt."If you look at the game, we took pretty much every chance we got bar one in their 22."Every ball that hit the floor bounced for us and we were on the right side of the penalty count."In the second half there were some big moments. We had a lineout around 45 minutes to take the game to three scores and it was a tough call by the referee to penalise us."We have a young group, we have not had a win for a while and those little scars can start to run deep."In the second half every bounce went for them, we had some key lineout positions we did not make the most of and the penalty decisions went away from us."Maybe the conditions added to that also but my instinct is not so much."Lake says Wales will look at themselves first."Conditions are going to play a factor but we're not blaming that," said Lake. "We weren't clinical enough in the 22 and we didn't come away with points."Jones was proved right when he said before the match the team that coped with conditions would win the game, but the Australian also praised his opposition."For Wales to come from the northern hemisphere into those conditions is difficult," said Jones. "Like every Wales team, they were always tough to beat. They're a proud rugby nation and produce tough, good players." Second success for Jones and Japan Jones, who masterminded a second success against Wales for Japan following the win in 2013, praised his side's resilience after a slow start."For a young team's perspective, that's a very good win," said Jones"In the first-half, we were getting beaten in territory and possession. "We had a lot of nerves and frequently gave the ball back early in the phase count. "As a result, we were being beaten fair and square. But I sensed at half-time the players knew what to do."Jones praised the leadership of his captain Michael Leitch."With Mike's leadership in the second half, I thought they played a good 40 minutes of rugby and were really tough," said Jones."At times, we were able to break the Wales defence and our set-piece was absolutely outstanding. "I can't remember the last time I saw a front-row play 80 minutes in a Test match, especially in difficult conditions."

It hurts – Matt Sherratt urges Wales to use latest defeat by Japan as ‘fuel'
But Eddie Jones' Brave Blossoms stormed back in sweltering conditions, where the temperatures reached 34 degrees Celsius alongside a very high humidity reading, to win 24-19 and register only their second ever victory over Wales. 'I think you could see the feelings pitchside (at the final whistle), not just the squad but the whole staff,' said interim head coach Sherratt. 'To have a 19-7 lead in the first half and to lose the game at the end is obviously very disappointing. It hurts. 'Already we've got to quickly use that hurt to fuel next week. The great thing about this tour is we get a chance next week to put it right.' The second Test of the two-match series takes place in Kobe next Saturday, and Wales will certainly hope for cooler conditions than the stifling heat of Kitakyushu. Water breaks were taken in each half and there was also an extended interval under World Rugby's updated heat and air quality guidelines, to provide support to players playing in hot conditions. But Sherratt, who has now overseen four defeats since replacing Warren Gatland during the Six Nations Championship in February, insisted the oppressive heat was not a factor in Wales' latest loss. He added: 'If I'm honest I'd be making excuses if I said that. First half we took pretty much every chance we got bar one in their 22. 'Every ball that hit the floor bounced for us and we rolled the right side of the penalty count. Great crowd here in Kitakyushu! 🙌 Thank you so much to everyone for bringing the vibes ✨#JPNvWAL — Japan Rugby (@JRFURugby) July 5, 2025 'In the second half there were some really big moments. We had a line-out around 45 minutes to take the game to three scores, and it was a really tough call from the referee in terms of penalising us. 'It's a young group and we've not had a win for a while, those little scars can start to run deep. 'In the second half every bounce went for them in the aerial battle, and the penalty count went away from us. 'Maybe the conditions added to that as well, but my instincts (say) not so much.' Wales second-row forward Ben Carter will miss the Second Test against Japan in Kobe next week with a head injury (David Davies/PA) There were worrying scenes inside the opening 30 seconds as lock forward Ben Carter suffered a head injury making a tackle. Carter was prone on the ground after contact and treated for several minutes before leaving the field on a stretcher. Although the Wales camp reported later that Carter had not suffered a serious injury, Sherratt said: 'Ben will be unavailable next week. 'We'll have a discussion with the staff to see what we'll do about that. But we've got cover here with Freddie (Thomas) and Ted (Williams).'

Japan 24-19 Wales: Welsh losing run extends to 18 Tests after desperate defeat by Eddie Jones' side
Wales' horror losing sequence is now at 18 Tests after Matt Sherratt's side plumbed new depths with a 24-19 defeat by Eddie Jones ' Japan in Kitakyushu. Welsh rugby has had a truly awful two years but the national side's latest loss in the Far East was a fresh low. Wales should have had enough to win what was a low-quality contest. But they failed to close out the game despite facing a Brave Blossoms side that was at their best mediocre and often incredibly poor. Somehow, Wales still found a way to lose. Sherratt's men were in control for two thirds of the match, but failed to score after the break. Their winless run is now at a mammoth 638 days, dating back to October 2023. Sherratt is the interim Wales head coach, as the Welsh Rugby Union continues to search for a new permanent boss. 'To lose the game at the end is obviously very disappointing,' Sherratt said. 'It hurts. We've got to use that hurt. The great thing about this tour is we have next week. In the first half we pretty much took every chance we had bar one. 'It's a young group and when you haven't had a win for a while, those scars can start to run deep.' Wales were without Jac Morgan and Tomos Williams after both were selected by the British & Irish Lions. But what is most concerning is that those two fine players apart, this was close to the best side Wales could put out. And they were beaten once again despite their opposition's paucity and the fact former England coach Jones fielded eight Japanese debutants. Wales' players have simply gotten out of the habit of winning both at domestic and international level. Captain Dewi Lake was crestfallen at the final whistle. 'A couple of mistakes and ill-discipline cost us dearly in the second half,' he said. 'We allowed Japan into the game and they're tough to stop when they're playing at speed. 'Although we felt like we were in control, if you don't score points, you're not going to win games. Conditions are going to play a factor but we're not blaming that. 'We weren't clinical enough.' Wales endured a worrying start, lock Ben Carter seemingly knocked out just 27 seconds into the game. Carter was taken from the field on a stretcher, but was on his feet by half time. The outstanding veteran No 8 Taulupe Faletau created Wales' first try, setting up Ben Thomas before Japan hit back with a set-piece move. Takuro Matsunaga was the scorer. In sweltering temperatures which touched 30 degrees, both teams took regular water breaks. The first half was played at a slow pace, suiting Wales. Japan's accuracy was particularly disappointing. They conceded a penalty try for which Ichigo Nakakusu was yellow carded and Tom Rogers grabbed Wales' third. The stop-start nature of the game and the heat breaks meant that 90 minutes after kick-off, the match clock hadn't even hit the hour mark. The last time Wales played in Japan, they reached the semi-finals of the 2019 World Cup with a team packed full of world-class talent. But now things are very different. Welsh rugby has been hit by all manner of problems since then. Sherratt's side should still have been further clear, but they failed to do so. And on the hour mark, Japan suddenly clicked into gear. Nakakusu made amends for his sin binning and the boot of Seungsin Lee cut the Welsh advantage to just two. Then, things got even worse. Wales offered nothing in the final quarter and Halatoa Vailea's try in the 70th minute won the game for Japan. Wales will face Japan next Saturday in the second Test in Kobe. 'We're gutted. It's very tough to take. We had moments to win that game and put it to bed,' Lake said. 'We've got to be better around our accuracy.'
