The cave (or grotto) where Minamoto no Yoritomo and his retainers, after being defeated at the Battle of Ishibashiyama, are said to have hidden from the Heike army. The name "Shitodo" comes from a bird of the same name that flew out of the cave when the Heike forces approached, helping Yoritomo and his group to escape unharmed.
Having safely fled, Yoritomo and his men escaped from the rocky coastline of Manazuru and sought refuge in Boso, where they planned their comeback.
In Manazuru, many people with the surname "Aoki" have lived for a long time. This is said to be a tribute to Yoritomo, who camouflaged the entrance of the cave with an "Aoki" tree when he was hiding. As thanks, he bestowed the surname "Aoki" on those who helped. Similarly, the surnames "Gomi" and "Onmori" were given to those who provided food support or served as lookouts, and they remain common in Manazuru to this day.

It’s just a historic site, so if you’re not a fan of Yoritomo, it might not be very exciting. However, since it’s within walking distance from Manazuru Port, it could be nice to stop by casually and reflect on the ancient periods!
