I was reading the drop logs on the JP wikiwiki site and there were rare reports of I-401 dropping from E4-G Hard (the Princess node that you got sent for having a failed check to the boss node at E; this can be induced by putting a submarine into the fleet 2). I am not sure how authentic that is, but it may something worth trying if you are really done farming else where.
