Archaeological view
A 32.7m keyhole mound at Oharano Iwami-cho, Nishikyo-ku, Kyoto, with a surrounding ditch and haniwa. Kyoto City's 2015 site briefing dates it to between the end of the 5th and the beginning of the 6th century, while the Kyoto Prefectural Archaeological Research Center's 2024 exhibition catalogue gives the early 6th century based on surveys in fiscal 2013–2017. Its rear contains a right-sleeved horizontal stone chamber; Kyoto City's site-briefing notes that, if this is the original burial facility, it would be the oldest horizontal stone chamber in the Otokuni area.
