Since there is a number 71 on the tail wing, the airframe is thought belonged to IJN carrier Zuiho.
Zuiho had 6 B5Ns and their main mission was reconnaissance being equipped with various cameras.
A local reseacher says the photo might have been taken by another B5N to be kept privately in the post war.
Just my guess![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
