Overview
The Maebashi Futagoyama Kofun is located at the eastern edge of the Maebashi Plain, and is one of a cluster of kofun tumuli in the area. It has a total length of 104 meters and was built in two tiers, orientated to the northwest. The surface was originally covered in fukiishi with rows of cylindrical haniwa. Unusually, the width of the rectangular portion is larger its length. The remains of a 35-meter moat were discovered in 1980, and an analysis of the soil covering the moat found that it contained volcanic ash from an eruption which occurred in the middle of the 6th century, indicating that the tumulus was built around the start of the sixth century. Although the detailed structure of the mound has not been investigated yet, it is believed that the burial chamber was opened in antiquity and has since collapsed.
