Male age-rank and tenure-rank relationships were studied for seven years in unprovisioned Japanese macaque (Macaca fuscata fuscata) troop on Kinkazan Island, Japan. Males whose estimated ages were between 15 and 19 yr old monopolized the highest ranks, while older males whose estimated ages were ≥ 20 yr old tended to decline in rank, resulting in a humped age-rank curve. The ranks of males tended to rise as their tenure in the troop increased. The departure of higher-ranking males was the social mechanism for changes in rank, suggesting that the disappearance of higher-ranking males plays an important role in determining rank dominance.
