What is Mozu-Furuichi Kofungun?

Construction age and composition of the mounded tomb group

Location of  Mozu-Furuichi Kofungun Mozu-Furuichi Kofungun is a group formed of giant kofun spread across Sakai, Habikino and Fujiidera Cities in southern Osaka. Though divided into two areas ("Mozu" in Sakai and "Furuichi" in Habikino and Fujiidera), they have sufficient integrity and continuity to be treated as a single entity. More than 200 kofun were built within the tomb group between the late 4th century and the early 6th century, and, 89 of these still survive today. The largest of these tombs is Nintoku-tenno-ryo Kofun (mound length 486m, the longest in Japan). Next comes Ojin-tenno-ryo Kofun (425m, 2nd longest), then Richu-tenno-ryo Kofun (365m, 3rd longest), Nisanzai Kofun (300m, 7th longest), Nakatsuhime-no-mikoto-ryo Kofun (290m, 9th longest) and Chuai-tenno-ryo Kofun (242m), in that order.
