In Shinto, a mikogami () is a term used within the context of parent-child deity cults to refer to an offspring kami. A mikogami is also referred to as a byà Âeishin. The parent deity of a mikogami can be either a father (hikogami) or a mother deity (himegami), with the latter fitting into the framework of cults devoted to "mother-child deities"(boshijin').
The concept of a mikogami is illustrated in the fragmentary Tsukushi-no kuni fudoki, which describes a three-peaked mountain called Kishimayama. The southwestern peak is named hikogami, the middle peak is the himegami, and the northeastern peak is the mikogami (offspring-kami).
Mikogami is a "subordinate" deity ().
A mikogami often is enshrined in an affiliated shrine, known as wakamiya. While most of these are dedicated to the offspring of the central deity (waka means "young"), some may enshrine a parent or ancestral deity. Furthermore, some wakamiya serve as temporary sites (anzaisho or ') for the main deity during festivals. Therefore, the shrine being a wakamiya does not necessarily imply the enshrinement of a mikogami.
Term boshijin is used in case a joint shrine is dedicated to mother goddess (boshin) and her mikogami.
Specific instances of mikogami enshrinement can be found at several prominent shrines in Japan:
Boshijin can be found in Kamo shrines and Hachiman beliefs. In the latter case, Hachiman shrines enshrine both Emperor à Âjin and his mother, Empress Jingà «.
