This is not a Mesoamerican pyramid or a ruined fortress; it is a hill covered with terraced stone walls on which gravestones stand.
Yagoto Cemetery in Nagoya comprises many hills like this one and houses approximately 50 thousand gravestones of people of different religious orientations as well as those of no religious orientation.
The cemetery is civil in the sense that any resident of Nagoya, regardless of his/her religious orientation, can apply for a space there. You don’t even need human remains to apply for a space.
The giant city-run cemetery is worth a visit if only for the view of the tens of thousands of gravestones blanketing hillsides and looking like fortresses with countless battlements.
Yagoto Cemetery is a few minutes walk from Nagoya Metro’s Yagoto Station.
