Jigoro had a steadfast devotion to his students and strict training. Despite his status as a strong mentor and experience as a previous Hashira, he had a soft spot and unwavering dedication towards raising the next generation of students. Due to this passionate devotion, he was filled with grief after discovering that his former pupil, Kaigaku, betrayed the Demon Slayer Corps and joined the ranks of the Twelve Kizuki.

Zenitsu Agatsuma noted that, despite how often he whined and ran away, Jigoro never gave up on him once. He had saved Zenitsu from a lifetime of debt and taken him on as a student, and, showing unyielding patience, was happy just to see Zenitsu master the first form of his breathing technique. He had a great belief in training skills to perfect through repetition comparing it to forging and purifying the steel of their swords. This strong fatherly love for his students is further shown when he shown to be both flattered and touched by Zenitsu's declaration of his love and gratefulness for all of his efforts put into forcing Zenitsu to improve himself despite everyone else abandoning him and deeming him worthless.
