In the mountains of Nikko, just a short train trip from the modern, glittering megacity of Tokyo, a handful of monks still practice a millennia-old tradition known as shugendo, a form of meditation via endurance-testing communion with nature.
These are the yamabushi, mountain monks for whom a dip in a thundering, ice-cold waterfall and a sopping-wet stroll up a mountain are just another day’s work.
