Host nation New Zealand ran in 13 tries as they thrashed Japan 83-7 in Hamilton.
Centre Ma'a Nonu was the star in the first half, orchestrating a fluid attacking display from the All Blacks, while Sonny Bill Williams came off the bench after half-time to score two tries.
Nonu's centre partner Conrad Smith began the scoring, before Richard Kahui (two), Jerome Kaino, captain Keven Mealamu, Andy Ellis, Colin Slade, Isaia Toeava, Andrew Hore, Nonu and Adam Thomson all crossed for tries.
The All Blacks had too much power and precision for their opponents, who defended in determined fashion, but had no answer to the intelligent running lines and good handling of Graham Henry's side.
For Japan, Hirotoki Onozawa stole an attempted offload by Slade in the second half and stole away for a consolation try. After the minnows of world rugby had made such an impression in the first week of competition, it was reality check time at the Waikato Stadium.
As preparation for next week's big game of the pool, between New Zealand and France, the game would have been of confidence-boosting benefit for the All Blacks, as well as a chance for lesser lights in the home squad for game time.
As Japan had named a less experienced XV for the contest it was no surprise that even with the changes forced on the All Blacks as the result of injuries they poured on the pressure on from the outset.
Apart from some early handling hiccups, the New Zealanders were in complete control, as the scoreline suggests, chalking up 38 unanswered points in the first half.
The tempo they were able to achieve, the drive the forwards were able to switch on, seemingly at will, and the cohesion and speed in backline moves was more than the Japanese could cope with.
The situation allowed flanker Jerome Kaino to demonstrate his continuing worth in the overall forward effort.
His fellow flanker Adam Thomson, originally named at No.8, settled back after injury, relishing the looser exchanges.
Scrummaging issues kept referee Nigel Owens occupied throughout the half with prop Tony Woodcock attracting plenty of attention from Owens and his touch judges.
New Zealand wasted no time in making a mark on the scoreboard with centre Conrad Smith marking his 50th Test by scoring the opening try, coming after a turnover on halfway.
Kaino cleared quickly and Vito charged ahead making room with centre Ma'a Nonu and fullback Isaia Toeava carrying the ball forward for Smith to polish off.
Nonu became the playmaker in the backline with several moves being worked off him and it was only occasionally that he featured in running the ball.
He typified his distribution with a superb inside pass for Toeava to set up first fly-half Colin Slade's try five minutes from halftime – the sixth try of the half.
New Zealand's superior forward power was obvious in the second try in the 16th minute. A clean lineout take was moved through the line for wing Richard Kahui to go across in the left corner.
Japan's try came in the 58th minute from an intercept as Slade attempted to find Toeava and wing Hirotoki Onozawa raced away to score.
