The original name for “Twintown” (PS1overseas) and “Aukba” (PS2overseas) is アウクバル (
aukubaru). The name may be a direct reference to Ackbar (a.k.a. アクバー,
akuba^ or アクバル,
akubaru, in Japanese which is another way to spell Akbar). The Admiral Ackbar was the Star Wars character featured in the famous “It’s a trap!” scene.
Interestingly, Myaw was our “Admiral” in the game, because he was the one that warned us if the floor or the chest was “a Trap!” or “not a trap!”. In any case, the Twintown (Auckbar) was the only town where we should avoid being tricked by Dezorisians’ entrapment Information. I can imagine talking to the wrong Dezorisians while Adm. Ackbar saying “It’s a trap!”. So "Aukbar" (PSjp) = "Akubar" (SWjp)...

Regarding to Aukbar (Twintown/Aukba) being Jut, I never heard that in the game. I’m assuming what lead you to think Auckbar may be Jut is the fact that in PS2 there are only 3 Dezorian towns in the game: (Ryuon, Zosa and Ackbar) and in PS4 there are also only 3 tows (Ryuon, Zosa and Jut) and Jut is symmetrical like Ackbar in PS1 (but in PS2 is not even symmetrical).
The town of “Jut” is localized near Gunbious, a temple that was erected where the old Corona Tower was 2000 years prior. Although PS1 Dezomap is wrapped everywhere, I don’t think we can’t make it near Corona. However I can tell that in PS2 Dezomap, Auckbar is at North of Sucre (Skure) and it should be
more or less where that pink dot is (btw, orange dot would be “Menobe” and green dot “Naval” dungeons).

Another example (using the unreleased “Monitor” of PS4):
Green dot = Auckbar Town (Twintown/Aukuba)
Red dot = Menobe Dungeon
Blue dot = Ikuto Dungeon
Blue dot = Naval DungeonEven PS1 map can make sense with other games if we see it upside down. Just rotate it at 180 degrees and you’ll have:
Note: Since it is a wrapped map in every direction, I cleaned the repeated locations (this had rules, strictly obeyed, because repeating or crossing the “same” paths would be cheating – every pixel shown is not repeated nor missing).The result was interesting because we can get Auckbar at north of Skure, Guaron Dungeon at the right of Skure and Corona Tower in the same position of Temple Ngumbious, just like in PS2 and PS4 Dezo maps. Even the forest where we used the Eclipse Torch matches with the forest (now corrupted) where we also had to use the same Eclipse Torch (off topic: maybe Garuberk Force was seeded and corrupted the Laerma Tree at the center… who knows?).
So, concluding:
- we don’t have a single hint that Jut is Auckbar;
- Ackbar is not charted (that does not mean it doesn’t exist in AW2284 – the party just didn’t need to go there)
- There are at least 4 dezorisian towns: Auckbar, Xhosa, Luon and Jut (although there may be much more)
- it is possible that I may be missing something.
