I always found it interesting that the Japanese were focused on attacking the Panama Canal.
The I-400 was poised to try..

One of Yamamoto's plans was to use the sen toku (secret submarine attack), so that in the opening days of 1945, preparations were under way to attack the Panama Canal. The strategy was to cut the supply lines and access to the Pacific Ocean by U.S. ships. The plan was to sail westward through the Indian Ocean, around the southern tip of Africa, and attack the canal's Gatun Locks from the east, a direction from which the Americans would not expect and were little prepared to defend. The flights would, of course, be one-way trips. None of the pilots expected to survive the attack, a tactic called tokko. Each pilot was presented with a tokko short sword, symbolic of the ultimate sacrifice.
Just think of all the resources Japan was prepared to expend just to attack a few locks on the canal.... I cant believe it would be down more that a couple weeks... but than again I'm sure it was a "soft" target that would let the world know that Japan is not finished yet.
