蝦夷方言藻汐草

Okikurmi is directly attested as a named figure in Ainu narratives, and the recorded kana supports this spelling. Dictionaries describe a culture hero or deity, often paired with Samayunkur. The source’s identification with Minamoto no Yoshitsune is a historical narrative association; the linguistic matches do not establish that the two were the same person. Corpus occurrences support the name and its narrative use, without independently confirming that identification.
