Komae, in western Tokyo, takes its name from a word linked to Korean-peninsula migrants and preserves ancient burial mounds from the same era, and Takaoka in Toyama Prefecture has the Sakuradani group of two nationally protected examples of the same monument type. Which ancient Japanese tomb form is it?

Question

Accepted Answer

Kofun. Kofun are large burial mounds built for elites in Japan roughly from the late 3rd to the 7th century CE. Their signature keyhole shape has become an icon of the era; sites survive across the archipelago from Komae to Takaoka.
