Iirc, in Japan there's a culture of yakuza legitimacy, that treats the yakuza as if they were more or less respectable and useful businessmen. I could be wrong though. But maybe this can happen in yankeeland or another Free World less totalitarian place, where these criminal organizations are glorified as tough Pinnacle Men acting outside the boundaries of petty laws.
Kinda related with Japan, now in the TL nipponese culture is being eliminated because Steele (and by extension, the steelist age RU) still despises the nipponese and believes " yellows are yellows no matter how pinnacle the Church or the marxists say they are", but Lincoln MacArthur seems to have a fondness for the Holy Nippon, and we know Oswald's "liberalization" is going to change race relations among the Pinnacle Peoples, like for example how race mixing between Anglo Saxons and Pinnacle Blacks will be permitted. So is possible that MacArthur or his son, with Oswald's graces, could launch an "Nipponese Eastern Jews" culture revival.
This revival would involve lots of archaeological investigations on anything from ancient Nippon that may be left still or to discover yet, propaganda on how the "Eastern Jews" are rediscovering their "true past" free from steelist racist suppresion, an A E S T H E T I C S theme based on what they think Ancient Nippon was, etc. But because Nippon has suffered Steele's cultural suppresion for years and years, has been a fascist country for more decades and there's not enough of Ancient Nippon left, this whole vision is a very weird fascistic image of the "honorable Eastern Jew shogunates" with Pinnacle Samurais slaying the "despicable slavic-mongoloid Ainus", Jehovah's Kamikaze wind smitting upon the mongoloid hordes, and shintoist mithology is converted into "magickal spirits", etc. Ninjas are compared to the current government secret services and state police inspectors so they can look cool and have a "secret spy order" image, and everything is horribly insulting and distorted to an OTL japanese man, but nipponese ITTL think the contrary. They have also it's own madnessified manganime culture influenced by Morty Krummhorn's animations. This manganime would have in the Free World the same reputation it has in OTL, and in the more "liberal" places there's a pinnacle weaboo trend.
Furthermore, I don't know if you've noticed it already but this "revived Nippon" aesthetic has a strong "cool exotic baddass Japan" tinge, both as a WMIT parody of Japan's image in american pop culture and because the Pinnacle Future is all about being the coolest and the hippest ever. If sexual marxism becomes a real thing ITTL, I can see too a rediscovery of old weird japanese sexual mores interpreted through the sexual marxist lens.
