4.5/5(52 reviews)

Walk up a cedar-lined path dotted with lanterns to see Hakone’s most famous Shinto shrine, standing between the shores of Lake Ashi and the peak of Mount Hakone.

When I first walked into this room I was so enthralled that I felt goosebumps over my hands!

I don't recalled having ever felt so in front of a scene and inside a museum. I felt lucky to be alive!!! And lucky to be in Japan again!

The picture here doesn't quite do justice to the holiness & majesty of this famous & revered mountain in Japan!
