One thing I've had to use multiple times on a few Toyotas was a 15mm 3/8" drive mid-length socket

Special Toyota tools consist of 10,12,14,15 and 19mm sockets and wrenches. Could almost dismantle the entire vehicle with those specialty items!
Kidding aside. Toyotas are pretty simple to work on. Some of the more involved or less common procedures can be sped up with specialty tools. Adjusting the valves, there is a little spoon like tool and a set of pliers that save you from needing to unbolt anything.
Yes the JIS driver is important, though all I can recall it being needed for are the A pillar "Oh s**t handles.
A 35mm socket is required to undue the hub nut in order to pull the front axles.
Oh there is also a handy little tool to speed up timing belt changes, it is a little clamp tool to compress the tensioner and saves you from needing to pull the AC compressor and bracket to reinstall the new belt.
what did you use the 15mm on?![]()

And the timing belt tool is not really needed I can access the tensioner with extension and 12mm 1/4 swivel socket I have done many and never had to remove ac compressor on 3.4l four cam on Tacoma/4Runner the rest is common sockets wrenches
But I would invest in a 10x1.25 time sert kit since tensioner bolts strip on these from being over tighten
+1. Not sure I have ever used a 15mm wrench or socket on a Toyota.
10mm, 12mm, 14mm, 17mm, 19mm and 21mm will cover most things.
do you have to have it? no, do you wanna get it done fast without problems - sure!
the tool would saves time, no messing around with the tensioner and completely avoid the possibility of striping out the threads or worse break a bolt in it
I just saw the picture you posted. I actually have one of those too.Otc makes a adapter for rear wheel bearing replacement
