One of six daughters of the lord Hosokawa Narishige, the little Princess Ko was
a child of a late second marriage; she was adopted by Narishige’s oldest son,
Naritatsu. Ko died when she was only three years old; the whole family grieved to
lose her, and her adoptive father, devastated by her death, commissioned a number
of memorial portraits of Ko to hang in temples under Hosokawa patronage.
