If you mean a Yakuza Series ITTL, it depends. The conditions that formed the Yakuza as we know it today aren't present in the Socialist Republic of Nippon, given that pre-existing Yakuza have largely been forced to move operations (to Entente South Asia, Australasia and even parts of Africa) after a series of post-war purging and are now largely syndicated with the similarly-displaced Triads to the point where they're largely the same transnational group, akin to the different US-based ethnic mob groups coming together in Americuba. Also, the discrimination against Zainichi Koreans and Burakumin which gave the post-war Yakuza a large part of its membership, while still not completely erased, has been effectively curbed.
Outside of Nippon, I could see a Not-Yakuza being produced in TTL's Malaysia or Singapore (or Hong Kong albeit largely more Chinese-influenced), but more on those places later.
