One particular theme instilled by Chile is a sense of "brotherhood".
They have four sets of brothers in their 33-man squad, with two - Alfonso and Diego Escobar, and Clemente and Domingo Saavedra - named in the starting line-up to face Japan today.
"First and foremost, we are a group of friends," said full-back Inaki Ayarza.
"Most of us have known each other since we were very young and many play in the same team. I think that's our strength - unity."

Most of the Chile squad will be unfamiliar to a British audience. Of the 33 players, 30 play their rugby for Selknam, a club in the capital city of Chile, Santiago.
An exception is captain Martin Sigren, who became the first player from the country to play professional rugby in England when he signed for Doncaster Knights in the second-tier Championship last year.
"He came to our attention through an agent who works for a lot of the guys from emerging nations," Doncaster Knights head coach Steve Boden told BBC Sport.
"Before this World Cup he mentioned he wanted to be in the best position possible to play in the tournament and we could give him that preparation.
"He is a smart guy and quite level-headed, as much off the field. He understands you can be the best rugby player in the world but the team environment and culture, that is more important than ability."

Japan v Chile (12.00 BST)
In 2015, Japan caused arguably the greatest upset in Rugby World Cup history by beating South Africa in Brighton.
In 2019, they made a mockery of all fears that they would struggle as hosts by beating Ireland and Scotland on their way to topping their pool and reaching the quarter-finals for the first time.
In 2023, expectations are much lower after an below-par build-up to this competition, including losses against Samoa and Fiji and an unconvincing win over Tonga in July.
That is Japan's only win in their past 10 internationals, and they have fallen to 14th in the world rankings.
But the Brave Blossoms are clear favourites today, and they will look to pick up five points and momentum from this game to carry into games against England, Argentina and Samoa in Pool D - where they will likely need at least two wins from three in order to repeat their heroics from four years ago.

Those of you who follow rugby more casually and are dipping in for the World Cup may be shocked to see Chile - hardly a major name in the global sport - competing at this tournament.
Chile have reached the Rugby World Cup for the first time in their history. They earned their spot when they beat the United States 52-51 in a two-legged qualification play-off in July 2022.
With the game finely poised, Chile wing Santiago Videla struck a 75th-minute penalty to make history for the South American nation.
Japan head coach Jamie Joseph said this game against the Brave Blossoms is "Chile's World Cup final". It is certainly a historic moment for the country, and a proud moment for the players.

"I think that is the call because Owen Farrell does not get into that team, Farrell is not any better than those players on the pitch.
"So why would you put yourself under the pressure to say I have to play him?
"There will be a point where Borthwick has to make that choice."

Former England winger Chris Ashton on England's performance on the Rugby Union Daily podcast: "We are going to have add that edge to us, we need a spark, we need something to just give us life and maybe a George Ford drop-goal is what we are after.
"Everyone is a bit more confident and everyone is a bit more comfortable now as we have beaten a good team.
"There is a big difference from being under pressure and then applying the pressure with 14 men.
"From the minute they had 14 men they just kept putting the pressure on, whether that was a Ford drop-goal, in defence getting off the line, getting over the ball and then slowing every ball down."

"I liked that underdog spirit. I wouldn’t necessarily say from the off because at the beginning, the first three minutes was a little bit not sure what was going off.
"[Tom] Curry got sent off and England zoned into this backs against the wall, it was like it ignited a different kind of creativity on how to win the game, headed up by George Ford."
Before we get going with today's action, let's take a look back at the other game in Pool D which took place on Saturday.
