There is not ruin in the center of the shellmound.
The survey result of the shellmound part is as follows.
The excavation survey of Arayashiki Shellmound in Chiba City was carried out from 1970 due to Keiyo Road (a part of highway network along Tokyo Bay) construction.
The center of the shellmound is the space with no sites. There are not remains of an ancient structure generally. This is considered to be a joint workshop/ meeting place/playground. Now, this place is used in the playground of children and dogs /the kite up convention/summer festival dances . There is a time machine here. When you come here, you may rejuvenate!
The survey result of the shellmound tells, the spiral shellfish called "Ibokisago"(I do not know English name) are overwhelming. This case is similar to Kasori Shellmound about 2 km away from Arayashiki Shellmound. As for the shell in the shellmound, do you think that clam and short-necked clam are main? There are few consumption of Ibokisago now, although the Ibokisago is eaten as the snack for alcoholic drink. Why are there a lot of Ibokisago shells?
1. Was the environment suited to the growth of Ibokisago?
2. Is it easy to manufacture dried shellfish from spiral shellfish than bivalve?
Considering the size of the shellfish, the dried shellfish might have been the seasoning. As they ate boiled food often in Jomon period, dried shellfish may have been used to add salty taste to the cooking.
