Abuyama Kofun
Abuyama Kofun (阿武山古墳)  is an Asuka period burial mound, located on Mount Abu, on the border of the Nasahara neighborhood of the city of Takatsuki and the Ai neighborhood of the city of Ibaraki, Osaka Prefecture, in the Kansai region of Japan. In 1934, the interred remains of an ancient nobleman were excavated from underground, and it has been hypothesized that the tomb was dedicated to the 7th century statesman Fujiwara no Kamatari, who is known as the founder of the powerful Fujiwara clan. The tumulus was designated a National Historic Site of Japan in 1983.
