I spoke to Toyota about this; how often it needs doing and how much they charge. The Service Manager said that while it is not in the service manual, he would clean it every 25 000 km or so. They don't pull it apart and manually clean it though; they spray some gear in there that loosens and dissolves the gunk... supposedly. It costs about $75 a treatment.
The real reason I was speaking to the Service Manager was to complain because they had done shoddy job of my 40 000 km service, so he offered to provide a free EGR clean at my next service. So, I got it done with the spray. I'm not sure what happens to the dissolved gunk? Hopefully made it's way out the exhaust... I dare say it's not as effective as a full manual removal but maybe if you do the spray clean regularly enough it then it will keep it clean so that dismantling and manual cleaning is not required?
