Snow Monkey Hierarchy: The Top Monkeys

The famous Snow Monkeys of Jigokudani are in fact Japanese macaques. This is a highly intelligent species of monkey which lives in large troops of over 100 individuals and is what are considered to be ‘matrilineal’ societies, meaning that a specific monkey’s lineage and status is traced through its mother.

THE STRUCTURE OF SNOW MONKEY SOCIETY


jigokudani-monkey-park-december-2020

An estimated 60 to 70% of the monkey troop is female, with different family lineages grouped together within one overall ‘dominance hierarchy’. Though mostly female, at the top of this hierarchy sits an ‘alpha male’ – the No.1 monkey and boss of the troop. Every monkey within the troop is named by park rangers with its lineage accounted for, with specific monkeys holding the highest ranks.

Many males, particularly those who are young or physically weak, will live apart from the main troop. Being unable to compete in the sometimes harsh male monkey social hierarchy, these monkeys will band together in their own smaller groups. They may eventually reunite with a larger troop, or travel for better opportunities. At the park, you can often see these monkeys nearby the entrance in smaller groups.

As for the higher ranking, more powerful monkeys, they can of course be seen inside the park. You will often know who they are by their large body size, steely gaze, and the reactions of other monkeys when they walk by. These are the top monkey power players in the park:

THE APLHA MALE: TOAMI 00

Born in 2000, Toami placed the old alpha, Tomamu, in 2019. Through the 1990s, many males were born into the troop and Toami is one of the youngest of that generation. He is aggressive toward the other monkeys and asserts his power through constant confrontations. His distinguishing facial feature is his prominent, protruding forehead. He is young, strong, and looks determined to hold on to his position as alpha for years to come.

THE NO.2: TOKEI 95-05

Number-3-monkey

The second in line to the throne of the Jigokudani kingdom is Tokei 95-05. Born in 2005 he is notably younger than Toami. Tokei is slightly built with somewhat black fur. Despite his slight and younger appearance, Tokei has a countenance permanently set to threatening. Young and confident, Tokei appears ambitious however hasn’t displayed the drive of Toami to establish himself as the alpha (at least, not yet).

HOW TO BECOME THE ALPHA MALE


jigokudani-monkey-park-december-2020

To understand how one male monkey becomes the alpha of the entire troop, you need to know a little about how the troop functions. Within the troop, the rank of females is often determined by the rank of their mother with female monkeys inheriting the status of their mother. The rank of males on the other hand, changes all the time. Males usually leave their birth troop upon early maturation – usually between five to eight years of age. From that time on, they will enter and leave several troops or even stay by themselves for years. Usually the rule is, the longer a monkey is with a troop, the higher its rank is within that troop. Also, male monkeys who develop a good relationship with the alpha female, will also rise in status and have more chance to become the alpha male.

The most typical way to become alpha is by death of the former alpha or if the former alpha leaves the group. The alpha male could also lose his rank because of another monkey being stronger and more suitable for the role. The alpha male is dominant and respected by other monkeys, but he is not the only male monkey with status and there are often multiple mature males with their eyes set on becoming alpha. For some, they will see it as a waiting game and bide their time while others might try to force the issue and challenge the alpha. So while Toami is alpha now, he always needs to keep on-top of what is happening around him and always needs to watch his back… as the saying goes, ‘the crown lies heavy’.
