During WWII, the Japanese military equipped officers with inexpensive stamped katanas, but as many of these officers were from Samurai families, they might well be entrusted by them with a
precious heirloom-- the ancestor's katana. Needless to say, many never returned. These two guys were buying the "war souvenirs" in the US, and selling them back to the families-- no doubt for a hefty profit.
This is just to say you may be sitting on a goldmine, at the very least.
Very true! In fact, I understand that there are a dozen or so important historical
swords that are "missing" from Japan, and the
men you describe were probably hoping to stumble onto one of these. The "
Orcrist" and "
Glamdring" analogues if you will. Swords that were carried by Shoguns or powerful daimyo in documented historical
battles etc. Also, older swords are far more highly valued in Japan than they are here. But there were also many thousands of lesser blades that have disappeared. In this case, I have had them examined professionally, and they are medium grade, not in top condition, and neither famous nor considered "important". Actually the collection my father amassed is more focused on the
sword 'furniture", especially the tsuba (guards) which achieved a very high degree of craftsmanship, as they were the most visible part of the Samurai attire.
The story my dad told about the acquisition of these is that, as a member of the occupation forces in Japan 1945-47 he was tasked with assuring that the population followed rules, and also that they were not victimized by organized crime. One rule was the complete disarming of the population... not only firearms but swords and spears and archery equipment as well. Since many families had old swords, these were all required to be turned in, supposedly to be returned "afterwards". Any not turned in voluntarily were subject to confiscation. But the paperwork to identify the original owners was never properly attributed or kept with the swords. They were simply thrown into a heap in a storeroom. It was not a priority for the occupational government... they had much larger problems to face, such as the potential of a looming famine.
Now each American soldier had exactly one steamer trunk that they could bring home with whatever they could fit into it. Some of the guys would go in the storeroom and strip the swords down to the blades, so they could pack more blades into their trunks. My dad started out just picking up the leavings... the guards, handles, scabbards etc. He did get a couple of complete swords, but mostly bits and pieces. They were not acquired in battle.
As far as the modern Japanese government is concerned, this is all "looted" goods that should have been returned to the families, but since all the paperwork was lost or destroyed, it would require some real sleuthing to ever return these to their original families.
