Injury-hit Australia crushed Japan 63-30 in Yokohama on Saturday to kick off their northern hemisphere tour in impressive style.
The Wallabies ran in nine tries in a lopsided encounter as they followed up wins against world champions New Zealand and the Barbarians with a clinical display against the 2019 World Cup hosts.
Tevita Kuridrani muscled over for a hat-trick of tries and Samu Kerevi added two more, with utility back Reece Hodge a perfect nine from nine with the boot in his first test at flyhalf.
"We were really happy with probably about 60 minutes of our game," said Australia captain Michael Hooper.
"Japan's players fought hard and were really strong in the breakdown," he added.
"They turned us over too many times and put 30 points on us -- we've got to be better than that."
Kerevi's second provided the game's highlight, the bulldozing centre collecting a no-look pass from Kurtley Beale to cap a stunning move started by Henry Speight deep in Australia's own half.
Japan lost 47-27 to a world select side last week in a butter-fingered display but ill discipline cost the Brave Blossoms against the Australians, who scored further tries through Speight, Tatafu Polota-Nau, Nick Phipps and Rob Simmons.
The Asian champions were left stunned when Speight burst clear to score Australia's second try after just 11 minutes as the floodgates threatened to burst open.
Trailing 35-3 at halftime, Japan improved after the break with locks Wimpie van der Walt and Amanaki Mafi grabbing tries before Kazuki Himeno bundled over after the final buzzer to help Japan hit the 30-point mark, to the joy of 43,000 in Yokohama.
Japan captain Michael Leitch pulled no punches in summing up the match.
"We were up against one of the top four teams in the world and we felt the difference between our level and theirs," he said.
"Discipline in that first 20 minutes hurt us and we have to improve in a lot of areas before the World Cup."
Hodge was calmness personified with regular flyhalf Bernard Foley out through illness, while second-choice scrumhalf Phipps looked solid in place of the injured Will Genia.
Japan, who were destroyed 91-3 by Australia the last time they met at the 2007 World Cup, have struggled since winning three games at the 2015 tournament under Eddie Jones.
