# Zenkoji Temple

One of Japan's most important Buddhist temples, founded in the 7th century and welcoming pilgrims of all sects. The Okaidan — a pitch-black underground corridor beneath the main hall — is a tactile journey where you feel along a wall in total darkness to touch a sacred key. Kids universally love and fear it.

## Insider Tips
The underground Okaidan passage is the unmissable experience — genuinely pitch black, roughly 40 meters long, moving very slowly in single file. Not suitable for kids with claustrophobia but magical for the rest. The Nakamise shopping street leading to the temple has excellent Oyaki (stuffed dumplings) and soft-serve.
