How many people believe that Japan had been colonized by Baekje?

I don't believe that Baekje Koreans colonized Japan although I'm Korean. We Koreans are honest about our history unlike that Japanese, who still to this day try to justify there colonization of Korea by tampering history! And also it is highly likely that there are members in the Japanese imperial family who have traces of Korean in them. Korean history textbooks do talk about Koreans and Japanese people mingling together during their early history together before their relations went sour. I alse read a statement from Emperor Akihito who said that he felt a certain kinship with the Korean people because Japanese historical records talk about how one of the Baekje kings gave away one of his daughters to a Japanese imperial family member to be wedded together in matrimony!
