perhaps this is in bad faith, but don't you think it's plausible that ms appleton was just a government food scientist who was sent to japan as sort of U.S. ambassador and given a generic, americanized name? we know that resources were scarce during the war and that many changes had to be made, or simply were made to cut costs, in the production of lots of things at the time. it just makes sense when you break it down that traditional shoyu is time and labour intensive to make but improves the taste of even outright bad dishes. at a time when people were forced to eat whatever food was available to them demand was likely very high to the point of unreasonably outweighing supply. either officials at kikkoman reached out to american food scientists for a solution or they offered one up themselves, given the fact that food science was undergoing a huge international renaissance led by the americans during the 30s, 40s and 50s. americans have a tendency to synthesize food. they also tend to feel strongly about imposing their culture on other countries. it seems more to me like this is a story about the american government taking extra steps to obfuscate the story of how they semi-successfully tried to be the final nail in the coffin of widespread, traditional shoyu production. less like some kind of yakuza conspiracy somehow centred on one woman. just the perspective of someone who's felt compelled to do their own research. it's my opinion that the way you're presenting your findings leaves massive gaps as well as leaps to get over them. i can't speak for the things you haven't shared publicly, obviously, but it feels a lot like you're dancing around the point. good luck to you in your research, regardless of my own feelings.

I think I agree that you're either arguing in bad faith or simply aren't really paying attention to a wider picture here. It's common knowledge that postwar economics in Japan were heavily influenced and remain to this day connected to organized crime and the Yakuza as an old tool of the imperial/noble order. We also know for a fact that the CIA worked with the yakuza during American occupation in order to manipulate political culture and economic structures.

It's also a common conspiracy in Japanese circles (or at least so it appears, and I want to be clear I am not voicing this as more than preexisting theory/belief, so I will not directly source to give complete credibility; consider this as context for why I might be interested in investigating further, just in case) that Empress Michiko and the Seifun Milling Company had close under-the-table connections with America, which would further influence the traditional shoyu brewing culture.

Like, I feel as though if you seem to be aware enough that America's treatment of Japan was one of extreme hostility and cruelty with little-to-no care about the nation or its people, solely using it as a means to enforce American/Western ideals and principles onto an unwilling populace and using violence and illegal organized crime syndicates to fulfill those goals...then why are you acting as though it's sus of me to look at a single woman in 1947 having this much power/control over Japanese-American relations when you have said yourself that shoyu is the single most important ingredient for Japanese food of all time, and only moreso during war rations/scarcity times?
