Japanese Wrestling's Fictional Governing Bodies

[Duke Mongoose]

While re-watching 90s All Japan and All Japan Women's matches, it occurred to me that the championships in those promotions were not named for their promotion (AJW did have a few "All-Japan" titles that were tertiary belts, below the "All-Pacific" and "World" championships).

This got me thinking - why do many promotions in Japan have fictional governing bodies that "establish" and "recognize" their championships? I actually thinks it's a neat concept, I just don't understand the background.

Examples:
All Japan Pro Wrestling - Pacific Wrestling Federation (PWF)
All Japan Women's Pro Wrestling - World Women's Wrestling Association (WWWA or 3WA)
New Japan Pro Wrestling - International Wrestling Grand Prix (IWGP)
Pro Wrestling NOAH - Global Honored Crown (GHC)
Frontier Martial-Arts Wrestling (FMW) - WWA (Unsure of what it stands for, World Wrestling Association?)

It is basically all for show. Keep in mind that Japan has several martial arts/combat sports which are nationally popular. Those sports all have legitimate governing bodies. Professional wrestling in Japan has traditionally been presented more like a real sport, especially compared to what pro wrestling in America became in the 80s and onward. So, if you want to model your business on how legitimate sports operate, you recreate the things that they do. Having these fictional governing bodies is how they achieve that.

The WWWA is semi-legitimate in that it was the organization that Mildred Burke ran after she was shut out of the NWA. It did have Japanese women’s promotions under it’s umbrella, but those ended up dying out and had nothing to do the modern All Japan Women’s. The WWWA World Singles Title (the “Red belt”) was considered to be a continuation in the lineage of Mildred Burke’s championship. All the other titles created for AJW took on the WWWA name.

That's basically what I thought, but I hate to just go on assumptions.

And I was aware of the WWWA/Mildred Burke connection, but assumed that it wasn't a legitimate organization by the 90s.
