Ame no Mikumari no Kami is a Shinto deity associated with the division and distribution of water, particularly as it relates to irrigation and river sources, and is venerated at various Mikumari shrines across Japan, including sites in the Yoshino and Katsuragi regions. The name itself reflects this role, combining terms for heaven and the parting or apportioning of water, linking the deity to agricultural sustenance and the natural flow of rivers and streams. Over time, folk etymology associated with the phrase mikumari led some communities to also connect this deity with childbirth and children, though the primary documented domain remains tied to water and nature.
