New Zealand scored 10 tries on Saturday with five-eighth Richie Mo’unga contributing 22 points.

The All Blacks taught next year’s World Cup hosts a tough lesson in front a record crowd for a rugby match in Japan of 43,751 at the Ajinomoto Stadium.

Hooker Dane Coles scored New Zealand’s first try on his return after almost a year out with injury, while debutant winger George Bridge scored a double, including one with his first touch as an All Black, after coming on at halftime.

Japan competed in attack by scoring five tries to contribute to the 100-point tally for the match but could not contain the All Blacks in defence, missing 25 tackles on the way to an overwhelming defeat.
