If past incidents are any example, they will be cleaned up, fixed up by the medics, issued new replicas of their original period uniforms, and flown to Japan, where the Emperor will order them to surrender. The surrender will be taken by the highest ranking US officer in Japan, and that will be pretty much it.
If true, they followed their last orders (go guerilla, resist the Americans, fight on for the Emperor) for over 50 years. They will be treated with honor and dignity by our military throughout the process. Remember, these are Japan's MIAs.
Yes, and the example they provide of fidelity to Duty, Honor, and Country, should be highly respected.
If this turns out to be a true story, the Japanese will go crazy celebrating their return. Its interesting to note that the Japanese government didn't lift a finger to help its veterans in the first 15 years after the war. Large numbers of parents and grandparents of Japanese war dead were housed in countryside orphanages with virtually no food or heat assistance. Surviving soldiers who made it back were issued fresh uniforms, starched white, and provided a place to beg in front of national and religious shrines. It was shameful.
