Umashimade no Mikoto is a deity from Japanese mythology, recorded in texts such as the Kojiki and Nihon Shoki, who is regarded as an ancestor of the Mononobe clan and served as a loyal attendant to Emperor Jimmu during the founding of the imperial line. Traditions associate him with martial and ceremonial roles in the early Yamato court, and some shrines that honor him have come to link him with health and healing through local devotional practice. Such associations reflect the reverence held by worshippers rather than claims that can be independently verified.
