Ubayama Shell Mound（the National Historic Site）

Ubayama Shell Mound was formed between the Middle and Late Jomon period (5,000 - 3,000 years ago) on the plateau on the left bank of Ogashiwa river. This is a horseshoe-shaped shell mound, the site looks like the letter C layout. The length of the mound from east to west is about 130 meters and it is 120 meters from north to south. Like Horinouch Shell Mound also in Ichikawa city, the Ubayama Shell Mound also consists of more than thirty shell heaps, mainly comprising hamaguri clamshell (Meretrix lusoria) as well as Japanese littleneck (Ruditapes philippinarum) and shiofuki clamshell (Mactra veneriformis)

Ubayama Shell Mound has been surveyed many times since 1893, and among these studies the excavation excursion staged by the Tokyo Anthropological Society in 1926 has the foremost importance. The research uncovered human remains, artifacts, and the remains of a fire hearth and a pit house. This was the first time in Japan that the horizontal projection of the pit house had been entirely depicted. As for human remains, skeletons of five people were unearthed in total; one child, two female adults and two male adults. These are seen as valuable samples. The skeletons were folded into each other on the floor of a single pit house as if there had been some kind of accident. During the following excavations, many pottery vessels were unearthed. These fall into the Otamadai, Kasori EI, Horinouch I, and Kasori BI types, among others ranging from Middle to Late Jomon period. Furthermore, many skeletons as well as accessories and pottery of unusual designs have attracted attention in what seem to have been a cemetery. To date, 39 sites of Jomon pit houses and 143 skeletons have been unearthed.

The excavation from Ubayama Shell Mound are preserved at the University of Tokyo, Nanzan University, Meiji University and Museum Of Antiques in Ichikawa City on the next to Horinouchi Shell Mound.
