England will be promoted to League A if they beat the Republic of Ireland in Sunday’s Nations League match at Wembley.
“If we win, it sets us up really well for the year ahead going into the [2026] World Cup,” said Bayern Munich forward Kane.
“These are the camps where you build that culture and togetherness that lead you into the World Cup. It is just a reminder that playing for England is really, really special.
“For me personally it is one of the greatest things I do as a professional footballer.”
Thomas Tuchel takes over as England boss on 1 January and Kane said it was up to the experienced players to pass on the message about team culture to the younger ones in the national set-up.
“I’m sure Thomas will come in and have ideas and ways he wants to build his culture,” added Kane.
“Ultimately we have had some really good tournaments and it’s about sharing those experiences with the players who haven’t had as much exposure to that.”
The match against Ireland will be Carsley’s last in his interim role.
The 50-year-old has given six debuts during his five matches in charge and has leaned heavily on players he knows from his time as manager of the under-21s side.
Curtis Jones, Lewis Hall and Morgan Rogers all made their debut as an inexperienced England side convincingly beat Greece.
“They have the mentality to compete and now the challenge for them is to stay in the squad,” said Carsley.
“There’s that many quality players around and the competition is so extreme that they have got to make sure they stay in the race.”
Carsley also added he will catch up with Tuchel after the current camp to “talk through the players” and share his thoughts and experience.
