After the keyhole-shaped mounds were no longer built, mound construction would continue from the seventh century onward; but with other forms of tumulus built shapes: the square tumulus [(方墳) "hofun" in Japanese], circular tumulus [(円墳) "empun" in Japanese], and octagonal tumulus [(八角墳) "hakkakufun" in Japanese].
