駒岡堂の前古墳

駒岡堂の前古墳, also called 駒岡堂ノ前古墳, was a late Kofun-period burial mound in 駒岡, 鶴見区, 横浜市, and one of the 駒岡古墳群. It stood on a ridge running southwest from the hill that contains 駒岡瓢箪山古墳, on the northern edge of the 下末吉台地 along the south bank of 鶴見川.

The mound was about 25 meters long and is thought to have been a 前方後円墳, with its square front pointing north. It was largely levelled away around 1968 (昭和43年), so its detailed form is now unknown. The hill itself remains, and one mound is said to survive just northeast of the former site, but many other mounds and 横穴墓群 were also cut away.

Earthenware 埴輪 found at 駒岡堂の前古墳 included cylindrical pieces and 器財埴輪 in the shapes of 翳, 靫, 大刀 and a house. Their dating places the mound's construction in the 6th century. Nearby 横穴墓 were also reported. The finds, now mostly lost, are kept by the 熊野郷土博物館 at 師岡熊野神社, together with material from 山野古墳 in the same group.

Monuments of this kind in Japan are the great burial mounds of the Kofun period, built mainly between the middle of the third century and the early seventh century CE, a period named after them. Many had a keyhole-shaped plan, but plain round mounds, double-rectangle mounds and square mounds also existed, and their orientation was not fixed.

駒岡堂の前古墳 is a megalithic mound (tumulus with integral stones) in Japan. A typological estimate: 250 CE to 650 CE. No English Wikipedia article exists for it; the full text below is the Japanese article "駒岡堂の前古墳", shown in the original language.
