Judging from the pattern of the spray on the underside it appears to be from
where the drive shaft meets the diff, just after the flange with the bolts
holding the drive shaft.
Is there a seal of some sort in between the diff and the drive shaft.

JB. Yes there is a seal there and it is not too difficult to replace,
as long as you have one big socket for the pinion nut and then an
even bigger socket to use as a drift to push the new seal in.
BUT. Depending on how soon you have seen this after the leak started,
you may not have to replace it. A diff pinion seal leak is the
classic first sign of the breather being blocked. (Breather can't
function, diff heats up, air above oil expands with heat, extra
pressure cannot relieve through valve at end of breather, pressure
forces oil out of seal.)
I remember that a while ago you asked us about renewing your breather
set-up and to eliminate restrictions. So did you do it? If you did
not then you might have a chance to eliminate or at least reduce the
leak by dealing with your breather. But if you did, then its time to
do the pinion seal, but even your Yaris expert should not charge too
much as long as the operation is within his obvious technical limitations !
