Tsukahanazuka Kofun

The Tsukahanazuka Kofun (塚花塚古墳) is a Kofun period burial mound, located in the Asada neighborhood of the city of Ukiha, Fukuoka Prefecture Japan. The tumulus was designated a National Historic Site of Japan in 1922.

Overview
The Tsukahanazuka Kofun is an enpun (円墳) circular tumulus with a diameter of approximately 30 meters and a height of approximately six meters. It is located on the left bank of the Chikugo River, at the tip of an alluvial fan that originates from the foot of Mount Minou. It is a decorated kofun and contains a multi-room horizontal corridor stone burial chamber. Although the corridor section of the burial chamber has been lost, the existing length is eight meters, with the anterior chamber being two meters long and 2.5 meters wide at its maximum width, and the posterior chamber 3.4 meters long and 2.5 meters wide at its maximum width. The decorations are centered on the back wall of the posterior chamber, and extend to both walls near the back wall. The design is that of a red double concentric circle pattern on the left wall, and one double and triple concentric circle pattern each in red and green on the right wall. The mural on the back wall is divided into three parts: the upper row has a long warabi fern pattern, which has an unusual shape, and the middle row has two tiers of concentric circles, and the surrounding walls are also decorated with warabi fern patterns. In addition, it also depicts a small shield-shaped trapezoidal pattern, with a series of triangular patterns arranged at the bottom. Grave goods recovered from this tumulus include Sue ware pottery, copper saddle fittings, and a large sword, as well as around 400 small red beads. The excavated items are on display at the Ukiha City History and Folklore Museum. The tumulus is about a 15-minute walk from Ukiha Station on the JR Kyushu Kyūdai Main Line.
