In addition, since it has been said that many of Chinese social system and culture were directly transferred for the first time by ken-suishi, kento-shi, and students accompanied them, before kensui-shi and kento-shi went to China, almost no Chinese social system and culture hadn't been transferred to Yamato kingship in Kinai region, so Wa and Yamato kingship in Kinai region were obviously different.
更に遣隋使・遣唐使とこれに随伴した留学生達によって、畿内ヤマトに中国の社会制度・文化の多くが初めて直接伝えられたとされていることから、遣隋使・遣唐使以前は畿内ヤマトには中国の社会制度・文化は殆ど伝わっておらず、倭と畿内ヤマトとは明らかに別物である。
