This isn’t true for any Toyota parts. They don’t just slap a sticker on there. The parts are made to Toyotas standard in the same factory different quality Parts are made. Toyota overseas the production of their genuine parts. Same reason why denso oil filters be oem Toyota denso filters are not the same thing. The list goes on and onToyota do not manufacture brake pads, so there is no such thing as 'Genuine Toyota Brake Pads'.
They approach most or all of the pad manufacturers and ask who can commit to producing X million pairs for less than Y price - whoever can do it quickest/cheapest gets the contract. Somewhere along the production/distribution/retail line, a Toyota sticker is put on the box.
You can buy any pad that fits, and if you take the time to heat-cycle and bed the pad properly then it will be fine.
Remember that supply chains change all the time but recently we had a discussion in whihc it was deterined that Akebono make a lot of pads to order for Toyota

To add to what you're saying.. Did you know that Toyota makes their own part toolings and when the production run of parts is done (for that period of time or number of parts), Toyota takes that tooling back not allowing the supplier to make Toyota's parts without Toyota's name on it. I kind of think that's awesome they have that level of control over their parts.This isn’t true for any Toyota parts. They don’t just slap a sticker on there.
