Questions about this page
How many caves are there in Japan?
27 on this map, out of 754 nature & landscapes in Japan. That is what Wikidata records with coordinates, a photograph and a Wikipedia article, so it is a floor rather than a census.
What is the best known cave in Japan?
Reigandō. Cave in Japan.
Which caves in Japan are the least visited?
26 of the 27 rank as little known — a Wikipedia article in only a handful of languages. They sit at the bottom of the ranked list below.
Where does this information come from?
Every place is drawn from Wikidata (CC0), with photographs from Wikimedia Commons and a link to its English Wikipedia article. Selection is deterministic: a place is here because Wikidata files it under one of the classes this atlas carries and it has coordinates, a photo and an article. Nothing is written or chosen by an AI, and the ranking is simply how many Wikipedia language editions cover a place.
