Last year there were talks between Yoshihisa Ueno, the president of Super Formula promoter JRP, and the Suzuka race organisers to bring Japan's leading domestic single-seater series to the event.
Super Formula left a two-month gap between its first round in March and its second event in May for the F1 support event to potentially move into.
A support slot for Super Formula didn't materialise for 2024, understood to be due to scheduling and paddock logistics, but in an exclusive interview Suzuka president Tsuyoshi Saito says he would be keen to welcome the series in 2025.
"The decision is also down to Formula 1, but Super Formula is a top racing category in Japan," Saito said. "Therefore, it would be very exciting for us to have F1 and Super Formula in the same weekend.
"It is a possibility and we would welcome this option, but of course we are not able to decide.
"At the same time, we are not only focused on Super Formula. For us it is mainly about offering fans the best combination throughout the weekend.
"Of course, Super Formula is one of those possibilities, but the most important thing is to have the best weekend package."
