Hosuseri (火須勢理命) is a god that appears in Japanese mythology.
Frustrated with Ninigi's suspicion, Sakuyahime built a long birthing hut and set it on fire.
Amid the blaze, she gave birth to three male kami[2] - Hoderi no mikoto (Umisachi), Hosuseri, and Hoori (Yamasachi)[3] in that order.
[2] The prefix "ho" in their names can mean either "flame" or "heads of grain", while "suseri" is linked to "susumu" (to advance).
Hence, their names signify the progression of flames or the steady growth of rice grain.
