As a special case in the history of transportation in East Asian Seas,the marine inci-dent that befell Heguri-no Hironari,a Japanese envoy sent to Tang China,and forced him to drift to Kunlun and Linyi(Champa)in the 22nd year of Kaiyuan period(734),exposed the difficulties and challenges faced by the shipwrecked Japanese travelling to Tang in self-rescue in the East Asian Seas.Tang Dynasty's active and effective rescue measures and plans to deal with such incidents reflected an important aspect of Tang's policy towards Japan during the period of building a goodwill relationship in the first half of the 8th century.Meanwhile,how Tang responded displayed the historical role of Annan Protectorate in the rescue mechanism for shipwrecks in East Asia waters in that period,as a transit place for Japanese missions encountering shipwrecks and a port of entry.The fact that Hironari returned through the Bohai state testified to its function as a transit channel in the Tang-Japanese ex-changes at that time.It further revealed Tang Dynasty's macro control in East Asian regional affairs,the background for the evolution of the alliance between Japan and Bohai during this period,and how they coordinated and assisted in the repatriation of Japanese missions.
