OMF:2097, Brutal: Paws of Fury and ofcourse, one of the greatest games ever:

Bikini Karate Babes

The WCW/nWo series for the N64 was fantastic from my memory. Great 4 player co-op wrestling. I would say that's about one of the only 'true' American fighting genres & games available, other than the horrible MK series.

 that brings a tear to my eye :(

Def Jam Vendetta and Fight for NY were really good. They were co-developed by Japanese and American development studios.

I tried Tao Feng also, and it was ok. The co-creator of Mortal Kombat, John Tobias created it exclusively for the Xbox last gen. It's relatively unknown.

However if you expand your definition of fighting game to incorporate boxing games, which are very much fighting games, then EA Chicago has a killer series called Fight Night that rocks hard and the new Punch Out for Wii is being developed by Canadians.

If you were trying to shove it down people's throats that Japanese developers make better fighting games then this was a pointless thread since there's probably not a soul on Earth that would disagree with you. It's along the lines of making a thread asking what great first person shooters were made by Japanese developers.

All AKI wrestling games use the same engine, so you can add WWF No Mercy and Wrestlemania 2000 to that list as well.

The latter two games also have quite good story modes and pretty damn good CAW modes as well.

Great game but it's developer, AKI, is a Japanese company. I also say Killer Instinct Gold. I liked the arcade version of Mace: The Dark Age. The N64 port was only passable though.

Actually AKI developed those games. They're a Japanese studio.

@antfromtashkent-Yukes develops the Smackdown vs. RAW series, and every Smackdown game since it's inception on Playstation. They're also a Japanese developer.

I hate you, Wrestlemania 2000.  You and your damn wrestler creator and your Royal Rumble... robbed me and my brother and cousin of months of our lives...

 hmmm ure right.... How bout i change my suggestion to Fight Night Round 3 then

That will work. EA Chicago makes it. I'd also like to say that even though western developers are practically a non factor with fighting games, Fight Night Round 4 has a good shot at being the most enjoyable fighting game this year, even with the stiff competition of Street Fighter IV, Blaz Blue: Calamity Trigger and King of Fighters XII coming out. It's hard to top the excellence of finally getting to pit Tyson and Ali against eachother. That trailer had me salivating.
