Furthermore, since towards the end of the fifth and the beginning of the sixth centuries many of the old burial mounds where chiefs were entombed went into decline and new types of burial mounds emerged, it is thought that King Wakatakeru's strategy for strengthening sovereignty succeeded, although his power was temporarily weakened by rebellions from the former powers.
また5世紀末から6世紀初めにかけて、それまで首長墓を造営してきた古墳群の多くが衰退し、新興の古墳群が出現していることから、ワカタケル大王の王権強化策は成功したが、その一方で旧来の勢力からの反発を招き、その結果として王権が一時的に弱体化したとの説もある。
