The Three Lions captain will spearhead the team's attempts to end 60 years of hurt in North America this summer and recalled his first memory of the tournament being when he watched the team in action during the 2002 edition in Japan and South Korea.
Kane told Match of the Day magazine: "My earliest memory of watching a World Cup was in 2002. Because of the time difference in Japan, we got to watch it in the assembly hall at school.
"I remember watching David Beckham, Paul Scholes and Michael Owen and dreaming about one day playing for England and captaining my country.
"The World Cup is just special: it brings everyone together all over the world. And being able to play in it is just an incredible feeling!"
Kane also reflected on how "proud" his 10-year-old self would be to see where he is now.
The Bayern Munich striker said: "Great question! I think 10-year-old Harry would be extremely proud.
"It was something that I had dreamed of as a child. I remember meeting David Beckham as a kid. He was and still is a player I looked up to, and he was captain at the time.
"I remember feeling inspired by him to follow in his footsteps. There is no better feeling than leading my team out at a third World Cup and I can't wait!"
Kane is a big fan of manager Thomas Tuchel's "energy" and believes that the coach will be a huge asset for the team this summer.
The striker said: "Thomas came into the team with new ideas and his style of playing.
"You can see from the World Cup qualifiers, we didn't concede a goal, and winning eight games out of eight created a strong belief and set momentum going into the World Cup.
"I love Thomas' energy, the way he sees football and his tactics. I think with him as a manager, we have as good a chance as any!"
