位于亚洲东部的中国和日本,是一衣带水的友好邻邦。尽管隔着浩瀚的大海,远古以来便开始了连续不断的文化交流,如日本列岛旧石器和细石器的出现、陶器和农耕的发生、青铜器和铁器的输入等,都可溯源于中国大陆的古代文化。远在先土器时代,由于冰川的作用降低了海水面,日本列岛和大陆联结在一起,成为人类往来和文化交流的桥梁。不过从绳文时代以来,海水面重新上升,日本列岛已处于同大陆相隔离的状态,只有通过海路才可能与大陆发生文化联系。 China and Japan, located in the eastern part of Asia, are friendly neighbors of a strip of water. Although there are many seas across the sea, continuous cultural exchanges have taken place since ancient times. For example, the appearance of Japanese palaeoliths and fine stones, the production of pottery and farming, the import of bronzes and iron ware, etc. can all be traced back to ancient times in mainland China culture. Far earlier in the era of earth-mills, the sea surface was lowered due to the glacier’s effect. The Japanese archipelago and the mainland were linked together to become a bridge between human exchanges and cultural exchanges. However, since the Jomon period, the sea level has been rising again. The Japanese archipelago has been isolated from the mainland. Only by sea can cultural ties with the Mainland be possible.
