We all know Japanese macaques (also called "snow monkeys") as the primates with the best approach to releasing some midweek stress: soaking in the hot springs of Joshinetsu Kogen National Park. And there's plenty of that going on in this beautiful HD video from Jacob and Katie Schwartz. But there's also some grooming, snacking on snow and general monkeying around. Crank up that resolution and enjoy!
