No experience with this toilet, so I can't rate it as good or bad, but after skimming over the installation instructions, you should realize the water supply is on the opposite side from our standard. Not an insurmountable problem, but would need to be addressed. I saw nothing about replacement parts for the internal workings. Toto parts are off the shelf in plumbing shops everywhere. Would these be special order taking who-knows-how-long? Maybe not, but I'd sure want to know because every toilet eventually has to have these parts replaced. Perhaps some of the pros will have encountered these toilets and can provide first hand opinions.
