The is an archaeological site containing a Kofun period located in the village of Izumizaki, Fukushima in the southern Tōhoku region of northern Japan. was granted protection as a National Historic Site in 1934. 
Overview.
The cave-tomb dates from the end of the 6th century to the beginning of the 7th century. It is located on the slope of a tuff hill on the northern shore of the Izumi River, and was discovered in 1933 during the prefectural road expansion work, and was the first decorative cave tomb found in the Tōhoku region. 
The tomb is approximately 2.1 meters square and has a 1.15 meter house-shaped opening and domed ceiling. It is significant in that it is a decorated kofun with depictions of men, women, animals, boats, horses and eddy patterns, painted in red on the back wall, side walls, and ceiling of the burial chamber. Such decorated "kofun" occur primary in Kyushu, and this is one of the northernmost example yet discovered and indicates the penetration of Kofun period culture into lands traditionally considered part of the Emishi cultural zone. A small number of grave goods were recovered, including straight swords and copper rings
The tomb is one of a group of seven which were discovered at the same time, but was the only one of the group which was decorated. The tomb does not appear in any historical records and the name of rank of the person buried within is unknown; however, as it is located only two kilometers from the Shirakawa Kanga ruins, it may have been the tomb of a leader of a "gōzoku" clan ruling this area before it came under full Yamato control.
The site is located about 30 minutes on foot from Izumizaki Station on the JR East Tōhoku Main Line. It is normally closed, but a mural full-size photo panel is on display at the Izumizaki Museum in front of Izumizaki Station.
