The men's freestyle bantamweight competition at the 1964 Summer Olympics in Tokyo took place from 11 to 14 October at the Komazawa Gymnasium.

[1] Bantamweight was the second-lightest category, including wrestlers weighing 52 to 57 kilograms (114.6 to 125.7 lb).

If 2 wrestlers remained, point totals were ignored and they faced each other for gold and silver (if they had already wrestled each other, that result was used).

Four wrestlers were eliminated in this round, with Siraj-Din also withdrawing to leave only 7 men advancing.

Uetake won to claim Japan's first gold medal in the weight class since 1952.
