A note on this series: Although I published some of these photos earlier, the majority have been recovered from an old drive that took a circuitous route of more than five years, three continents and four countries to get back to me. I plan to run them in themed segments on Wednesdays this summer, including Tokyo nightlife, shrines, cityscapes and more. This week’s photos are from the snow monkey exhibit at Mt. Takao.
Japanese macaques are the northernmost-dwelling of any non-human primate species.
They’re built for the cold, with heavier coats than their cousins, the rhesus, long-tailed and bonnet macaques. They also sleep in well-organized groups, rotating so each monkey gets time in the center to soak up body heat, and they’re famous for keeping warm in northern Japan’s hot springs.
But as these photos show, snow monkeys are also adaptable, and they make the best of things during the hot, humid summers at Mt. Takao, about 51 km (30 miles) from Tokyo.
These photos were taken on a hot day in June when I was one of only a handful of visitors.














Macaque troops are headed by alphas who are the strongest males and deal directly with protecting troop members, but the matriarch runs most aspects of troop life.
Here, a snow monkey mom hugs her child. The bond between moms and their kids is strong. Daughters stay with their mothers and their troops for life, while sons remain in the troop until they’re about five years old, at which time they depart to avoid inbreeding. They often go on to live as bachelors in small groups before joining or starting their own troops.






Harry Harlowe’s infamous experiments in the 1960s proved that the physical comfort of being held is crucial to the psychological development of all primates, humans included. If a baby is denied that, the consequences manifest as severe psychological issues later in life.

Adios, humans!
