Got a link to the listing? Maybe someone swapped in a 99 locked axle.

Sorry, no link.

Yes, but it does show that it was intended for the European market, not USA (or North American) market, meaning that the US “rules” about AHC, ATRAC, locker, no diesel, automatic only, VGRS, full time 4WD, VVTI may not apply in your market
Partsouq is showing this an HDJ so this is the 4.5 liter turbo diesel 1HD engine model of the 100 series;
The standard 2001-2007 ATRAC on all USDM 100s is not applicable to African, European, Southeast Asian, and GCC spec 100s that had the 1FZ and 1HD engine options. It’s a whole different ball game overseas where there was so many options including sub tank, bench seating, oem spare tire swing out, barn doors, factory winch and factory electronic rear/front locking differentials.
Yeah I too have a 2001 HDJ100 European spec and there's no traction or stability control and there's a rear locker. It would be cool if those things were included, but not at the expense of the rear locker of course.

I’ve never seen/heard of a 100 with both factory rear locker and ATRAC.
Imo ATRAC is better than a rear locker alone.
With an 06 LX as my DD, and a 99 LX as “my toy”, with an aftermarket rear locker, I’m pretty sure that I could argue “either side”.
I could agree with this as well. Lockers add a capability beyond what ATRAC can do. ATRAC is (IMO) 80% as capable as a rear locker alone, but adds capability on the front axle that the rear locker can't. And I rarely use my front locker, most often preferring ATRAC in the front in any situation that doesn't require the wheel to be very straight. Slippery conditions, ATRAC is simply better than a locked axle.
Having said all that, I love having both axles locked.
If you have atrac and were going to add a e locker would you get a front or rear locker?

^^^ that's a good question and the answer would typically prioritize the rear locker first. In a climbing situation, weight goes to the rear. In a rocky situation, the rear has more articulation and likely to get a hold of something. Plus, you can steer much better with the front open.
If reliability and fear of breaking down is of most importance, I'd go with the front locker due to the added strength and also the last of down travel on the front of a lifted 100. The front end often lifts a wheel and coming down on a spinning wheel could also break the front diff. Locking the front diff before lifting a wheel will also prevent excessive wheel spin.

Fundamental reason why car manufacturers like Merc (Gwagon) and Toyota (LCs) sequenced their differential lockers to be 1st on the rear and 2nd on the front is for climbing/inclined obstacles. The rear is where the mass of the whole vehicle is directed to and that’s where it needs traction the most, 99% of the time. The front diff lock acts like another set of hands to pull the vehicle out of the obstacle. And by experience when you engage the rear locking diff, 99% of the time the vehicle is able climb up, unless the rear tire is not able to establish traction with the surface, too slick/tire not deflated/muddy surface.
I’ve always wondered about triple Torsens and ATRAC, but the open center diff of the 100 series makes this difficult.
