Sekizuka's side meet Akira Nishino's Gamba outfit in Osaka in the round of 16 of Asian Champions League action and will go into the game with a cautious approach.
"Coach Nishino has good experience and applies appropriate tactics one after another during the game, said Sekizuka.
"Gamba are aiming to defend their title so they will have a strong desire to win tomorrow's game and I am sure they will be different to how they are in the J. League.
"That's the same for us too. This is our second challenge in the ACL, and we are aiming to climb to the top of Asia.
"As our opponents are the reigning champions, we head into the game as the challenger.
"But it's a one-off match and it's going to be a real battle."
