Ming took the states' submittal as the external certification of governmental orhtodoxy. In this respect, Japan was a very important state. Because Japanese unyieldingness to Yuan dynasty had been portrayed as a protective attitude about "The Huayi Order". The record about Japanese King kaneyosisinnou's tribute in Hongwu 4th year maybe was a intentional description to satisfy the ertification of Ming's orhtodoxy. Thereafter, the relations between Ming and Japan had developed around submittal question.
