The Ireland players have no plans to meet the Haka with another double eight formation in Tokyo tomorrow - although that could yet change.
Famously, that formation was used in Soldier Field in Chicago in 2016, just a couple of weeks after Munster playing legend and head coach Anthony Foley passed away in Paris.
"Yeah obviously with the anniversary, he's been in our thoughts," said Conor Murray, who played alongside and then for 'Axel'.
"It's three years, isn't it, which is scary.
"And it's a bit of a reminder, when I saw it the other day, of what happened in Chicago. He played a massive part in that day, obviously, with the way we approached the Haka.
"There's been no real talk of that. I don't think respectfully there'll be any need to do anything like that. But he has definitely been in my head this week."
Ireland scrum coach Greg Feek, who led the Haka against Scotland when he played for the All Blacks almost 20 years ago, said it will be a decision made by the players' leadership group.
"Everyone understands what the Haka is about, and the tribute that it is, that there is a deeper meaning to it for the New Zealanders," said Feek.
"Those are the sorts of conversations that will take place amongst the senior boys over the next 24 hours, and we'll have a look at that a bit more to see what best fits the team first.
"The boys won't get too distracted in terms of doing what they do on their pre-game rituals and things. The key is that those last few minutes before the game begins are not too distracting.
"At the time, you're extremely proud, a little emotional, and you ask yourself 'how did I end up doing this'.
But then you just embrace it and you get the boys around you to support you.
It's just like playing rugby in that you just represent something like that as best you can with the utmost respect.
If I had have been a bit more mature I would have done it a bit better! I might have done it a bit fast at the time.
"But apart from that it's a privilege".
