The team has been named to face Scotland. It's getting serious now, just two days out from Ireland's opener.
"There's the realisation that the World Cup is here and there's an itchiness to get going". The words of Tadhg Furlong as he spoke to the assembled media in Yokohama.
For Furlong, it's a second World Cup after his "small involvement" in 2015, but the disappointment of the defeat to Argentina still lingers.
"We had fabulous support in Cardiff that day, but for me it's now about holding on to the disappointment I felt after that game and using that as a motivation to drive us on in Japan."
In the hope of something better over the next few weeks, the Wexfordman is very happy with the way things have gone in the planning stages.
"From here on, we'll be trying to stick with what we've worked on in the pre-season and in the warm-up games so we are not reinventing the wheel," he added.
"We had the four warm up games, I thought throughout we got better and better as it went on.
"You go through a lot of work, but it's tailored that in such a way that you hit you're straps at a certain point.
"We bounced pretty well off the back of the England defeat. To win in Cardiff was not easy, to beat Wales at home was not easy. Confidence grew within the squad. The work we've done in pre-season and since we landed here has left us in a good place.
Also at the top table was James Ryan, who also got the nod to start against the Scots.
And while the lock shares Furlong's view that preparations have gone well, he is also keen to point out the threat that Sunday's opposition will bring.
He said: "Our focus has been on getting the best version of ourselves so that we are bang on from the get-go. To that end things have gone well, both on and off the pitch. Our hotels, food, relaxation time, has been first class so far.
As for Scotland, you only have to look at the qualities they have.
"They've gone for Finn Russell at 10, combine that with the threats they have in the outside back area - Stuart Hogg, Tommy Seymour, Darcy Graham and Sean Maitland - they are some of the quickest, rapid guys in world rugby.
"When you put those two together, they are seriously potent side."
Still only 23, Ryan has been thrust into a position of great trust, tasked with bossing Ireland's lineout.
"I'm really excited, being here now it certainly feels that the game is fast approaching. It's a mix of nerves and excitement heading into the game now," said Ryan.
"I really enjoy playing alongside Hendy (Iain Henderson), he's a real smart player, and I think he is really physical.
"Whenever he's going forward, he's such a big man everyone follows behind. He's really intelligent in the lineout too.

"Hendy, Pete (O'Mahony) and myself will hopefully share the responsibility a bit in that area. And if Pete and myself see opportunities in the line we'll feed that back to him. But as I said I really enjoy playing alongside him, he's a super player.
"Absolutely I enjoy the responsibility of the lineout. I had a taste of it again last week, the last Wales game. So whenever I'm in that role I enjoy it.
"Certainly whenever Hendy, Pete and myself are there it's about sharing responsibility in that regard, so we're chipping in together. And combine that with the experience Besty has, I think when we get things right we can be strong in that area."
