Edo Bay has been an important source of food for people in Japan for millennia. Some of the earliest people who came to Japan, thousands and thousands of years ago, lived along this coast, and the huge mounds of shells built up from the seafood they collected in the shallows of the bay can still be seen today.
In Edo Japan, the people do not eat meat, since Buddhism teaches that it is bad to kill animals. Therefore, fish and birds such as ducks and geese are an important part of the diet. Edo Bay is a rich source of seafood and game. In fact, it is one of the two richest fisheries in the entire country. (The other is the Seto Inland Sea, between Sakai (Osaka port) and Kyushu.)
