Japan vs Australia Prediction: Wallabies Eye Winning Start Under Les Kiss

Australia begin a new chapter under head coach Les Kiss when they travel to Osaka to face Eddie Jones’ Japan on Saturday in what promises to be an entertaining international Test.

While the Wallabies arrive with renewed confidence after ending their losing streak with a convincing victory over Italy, Japan have steadily improved under Jones and are chasing a historic first-ever Test victory over Australia. The Brave Blossoms will also have home support behind them in what is expected to be hot and humid conditions at Hanazono Rugby Stadium.

Match Details:

• Fixture: Japan vs Australia
• Competition: International Test Match
• Venue: Hanazono Rugby Stadium, Osaka
• Kick-off: Saturday, 8 August 2026 (12:05 SAST)

Australia enter the match under new coach Les Kiss, whose first Test in charge comes against former Wallabies mentor Eddie Jones. Captain Harry Wilson leads a squad packed with experience, while Charlie Cale returns after a lengthy injury layoff and loosehead prop Aidan Ross earns a starting opportunity.

Japan have made several changes to their forward pack while retaining much of their dangerous backline. Captain Warner Dearns leads the side, with Ryunosuke Ito steering play at flyhalf and Dylan Riley providing plenty of attacking spark in midfield. Veteran Michael Leitch offers valuable experience from the bench..

Harry Wilson (Australia)

The Wallabies skipper has become Australia’s heartbeat. His ball carrying, leadership and work at the breakdown could prove decisive against an energetic Japanese pack.

Rob Valetini (Australia)

One of the world’s premier loose forwards, Valetini consistently wins the gain line and gives Australia valuable front-foot possession.

Warner Dearns (Japan)

The towering lock captains Japan and will be central to disrupting Australia’s lineout while leading the physical battle.

Dylan Riley (Japan)

Australia cannot afford to give Riley space. His pace and footwork make him Japan’s biggest attacking threat.

Japan will aim to play at a high tempo, moving the ball quickly through multiple phases while forcing Australia’s bigger forwards to defend for extended periods. Eddie Jones’ side thrive on counter-attacks and quick transitions.

Australia, meanwhile, possess greater power up front and should enjoy the advantage at scrum time. Expect the Wallabies to lean on their set-piece, kicking game and dominant forward carriers before releasing their dangerous outside backs.

The hot Osaka conditions could also play a significant role, making discipline and fitness crucial throughout the 80 minutes.

Australia -18.5 Handicap @ 1.90

Australia’s superior pack should create enough scoring opportunities to cover the handicap, particularly during the final quarter.

Confidence rating: ⭐⭐⭐⭐⭐ (5/5)

Japan have improved significantly throughout 2026 and playing at home certainly gives them a chance to stay competitive.

However, Australia simply possess greater depth across the park. With Rob Valetini, Harry Wilson and Fraser McReight leading an imposing forward pack, the Wallabies should gradually wear down the Brave Blossoms.

Expect Japan to produce moments of brilliance, but Australia’s physicality should prove the difference during the second half.

Prediction: Japan 22-34 Australia

Several factors favour the visitors:

• Superior forward pack.
• Greater bench depth.
• Strong scrum advantage.
• Experienced international leadership.
• Japan are still searching for their first-ever Test victory over Australia.
