| Outline of Final Research Achievements |
The path of negotiations with the mainland is limited because Japanese archipelago is surrounded by the sea. As the start of the Yayoi culture, negotiations with the mainland thorough the Korean Peninsula were common. In northern there was the another route via Sakhalin but, this route is also contemplated, such as if they were always open, has not been elucidated empirically far. In this project we sought to identify the timing of this northern corridor was substantially function. Our answer is that after Hokkaido and Sakhalin was disconnected because of the rise of sea level only in the Holocene, archaeologically there was only one short time of active negotiation at of the early Jomon period. And after then that path had remained essentially closed up to the epi-Jomon period.
