Izusan Gongen at Atami on the Izu coast was Yoritomo's prayer-shrine in exile and rising and, with Hakone, one of the 'two shrines' (Nisho) that the Kamakura lords visit at the New Year.
Yoritomo's exile was in Izu, a few miles from here; the Hōjō's home at Nirayama is near. Izusan is held by mountain monks (yamabushi) and has no known warrior force. It is the sort of place the campaign can use for a pilgrimage of Yoriie in the first month.
