Soka Gakkai's and Nichiren Shoshu's creation of history

Niko [not Nikko] accompanied Nichiren to Sado Island and remained with him the entire time there. Another example: Nikko founded Taisekeji but spent the last 36 years of his life at Kitayama Honmonji temple, his grave facing Minobu. Were the DaiGohonzon at Taisekeji when he died, his grave would have faced Taisekeji.
