Ubayama Shell Mound（the National Historic Site）

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.

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.
