Stone covering and haniwa have been restored, allowing direct experience of the ancient mound appearance. Maintained by Fujiidera City with replica haniwa installations. Together with the adjacent Otoritsuka Kofun (id:32), forms the centerpiece of the northern Furuichi group visitor experience. Within walking distance of Kintetsu Furuchi and Hajino-Sato stations.Constituent monument of the "Mozu-Furuichi Kofun Group" UNESCO WHS (2019). The name "Furumuroyama" may be interpreted as "Old Chamber Hill" (ancient stone chamber hill), suggesting that the presence of a burial chamber was recognized here from early times. Open-access mounds in the Furuichi group are rare; Furumuroyama and a handful of others (Otoritsuka, Hazamiyama, Minegatsuka, Nonaka) are the exceptions. Among these, climbing to the summit of the rear circle to survey the surrounding landscape offers a rare chance to approximate the commanding vantage point once envisioned for Kofun-period rulers, making it a favorite among kofun enthusiasts.
Surveys by Habikino/Fujiidera city boards of education confirmed fukiishi and haniwa rows. A vertical-shaft stone chamber in the rear circle is presumed but detailed excavation remains limited.
