Tamaishigaki (round stone walls) are found in many places, but this one has a sign. A little further on there's an explanatory sign about the road-widening project (the stone walls were relocated too), and sometimes the town-run sightseeing bus stops there.

Stone walls built by exiles. Stone walls made of neatly arranged round stones all the same size??? On a volcanic island? Even if you look for round stones in a nearby river you can hardly find any, amazing.

The round stone walls that also appear in Detective Conan

I found out it's one of the Eight Views of Hachijo.
