Defending Rugby World Cup champions New Zealand took part in their first training session on Tuesday after touching down in Japan a day earlier.

The All Blacks arrived in Tokyo on Monday before making their way to their base in Kashiwa, where they were given a hero's welcome by a group of schoolchildren performing the haka and hundreds of fans.

But it was straight down to business for the tournament favourites, who were going through their paces at the Kashiwanoha Stadium on Tuesday as they look to quickly adjust from the winter temperatures of back home to the sweltering heat of Japan.

All Blacks scrumhalf Brad Weber said they were well prepared for the 20-degree Celsius swing in temperature, with the mercury touching the mid-30s on Tuesday.

"We had a few strategies when we were back home to try and be in hot conditions," Weber told reporters. "We were well prepared for the heat here."

Weber added that the conditions were similar to those teams experienced in pre-season training for Super Rugby, which normally starts in early February - the tail-end of the southern hemisphere summer.

"For me, it's just like a pre-season." he said. "It's not like this is something outrageously different that we've never experienced - it's just a summer in New Zealand.

"The humidity is maybe a little bit different, but it's nothing outrageous I don't think."

The All Blacks open their campaign for a third successive World Cup title against South Africa on September 21 in Yokohama.
