Maebashi-tenjinnyama-kofun

This keyhole-shaped burial mound measures 129 meters in length with a circular rear section of 75 meters diameter and 9 meters height, constructed with three-tiered stone layers and surrounding moats.

Built during the 4th century, this tomb represents early Kofun period burial practices and was excavated in 1968, revealing over 160 artifacts including bronze mirrors and iron weapons.

The discovered bronze mirrors, particularly the triangular-rimmed divine beast mirrors, served as ceremonial objects reflecting religious beliefs and social hierarchy of ancient Japanese rulers.

Located near JR Ryomo Line's Maebashi-Oshima Station, the site offers educational displays and preserved sections of the original tomb structure for visitors and researchers.

The tomb's bronze mirrors share casting molds with similar artifacts found in Nara and Tottori prefectures, demonstrating ancient metalworking networks across Japan.
