The variety of foods eaten
From hundreds of thousands of excavations, it is now known that the remains of a wide variety of plants and animals were used at Jomon sites. There were over sixty species of mammals, more than 350 species of shellfish, over seventy species of fish, thirty-five species of bird and fifty-five kinds of plants. Although plant foods are very perishable and do not survive well in most archaeological contexts, we can see that Jomon people ate a wide variety of plants and vegetables.
Regional differences and seasonality
Excavations of shell middens and waterlogged or wetland sites have revealed differences in the foods used in various regions due to the differences in their environments. Different plants and animals are available at different times of year and this allows archaeologists to recreate the annual cycle of subsistence activities by local people. Jomon people followed the seasonality of each food resource, and they organised their food gathering through a carefully scheduled annual calendar.
