Beyond the giant red torii of this shrine, ancient tradition (and stern-faced priests) forbids disclosure of what you witness. It's forbidden to photograph and taboo to discuss this sacred natural shrine, so you'll just have to find out for yourself. It's quite remarkable. Strict rituals prevail: remove your shoes, bow your head before the priest for purification rites then follow the other pilgrims.
A bus stop is a mere 200m from the shrine, though buses run only on weekends.
