東京湾沿岸地域における縄文時代の鯨類利用

抄録

　In the Jomon period, dolphin and whale resources were actively exploited in three areas： 1. Coast of Nemuro to Kushiro, and Hunka bay (Hokkaido Pref.) 2. Coast of Toyama bay (Toyama and Ishikawa Pref.) 3. Coast of Tokyo bay (Chiba, Tokyo, and Kanagawa Pref.) 　This paper focuses on the coast of Tokyo bay, and examined how the whale and dolphin were exploited. In Tokyo bay, there were two exploitative situations of those resources. At the recess of the bay, we can find very few remains of whales. On the other hand, we can find many remains of dolphin and whole parts of the body at the entrance of the bay. However, other resources and products, especially obsidian and shell bracelet, show that the Jomon community had a trading system, so I think dolphin and whale resources were also probably divided along their network system.
