Perhaps the best part of Nanzen-ji is overlooked by most visitors: Nanzen-ji Oku-no-in, a small shrine hidden in a forested hollow behind the main precinct. It’s here that pilgrims pray while standing under the falls, sometimes in the dead of winter.
To get here, walk up to the red-brick aqueduct in front of Nanzen-in. Follow the road that runs parallel to the aqueduct up into the hills, and walk past (or through) Kōtoku-an, a small subtemple on your left. Continue up the steps into the woods until you reach a waterfall in a beautiful mountain glen.
