drowned body; corpse found in water
Colloquial and somewhat dated term for a drowned body, especially one that has swollen. Originates from the name of an Edo-period sumo wrestler, Narusegawa Dozaemon, who was pale and plump, resembling a drowned corpse.
I heard they pulled a drowned body out of the river.
People in the old days called a drowned corpse 'dozaemon'.
