Katori shrine

Katori shrine, across the water from Kashima, honours Futsunushi, the sword-god paired with Takemikazuchi of Kashima.

It is the Ichinomiya of Shimōsa and ranks with Kashima and Ise. Shimōsa's constable is the Chiba, whose branch lands lie nearby, so the Chiba are its natural protectors. The shrine's value for the campaign is as the ritual twin of Kashima; nothing else is known for 1200.
