Futarasan Shrine's Haiden is a small paid area on the left side of the main hall where you can chill among ancient trees, check out some extra halls, and get a closer look at the shrine's main building. It's like a hidden gem within the shrine grounds where you can escape the crowds and soak up the serene vibes of this sacred place. Don't miss the chance to explore this peaceful spot and connect with the spiritual energy of Nikko's three sacred mountains.
