No, Toto has a number of toilets in which the china is made in the US, and the "trim" (i.e. fill valve, flapper, etc.) are made in the US by Korky. Any toilet that takes the "red" Toto flapper uses a Korky flapper (at least it used to). I read a review on a major merchant's web site where an engineer went into Full Geek mode and compared the tool marks on the flapper that came with his Toto Drake to the tool marks on the Korky "Fits Toto" Red flapper, made in Wisconsin, that he had bought at Lowe's to replace it. (The Korky flapper you buy at Lowe's, being a factory-authorized product, actually says "Toto" on it.) He concluded that they were unequivocally made on the same machine; not the same type of machine, the same machine, in Wisconsin. Depending upon where the Toto toilet is molded, you may or may not get it with a Korky 528 fill valve, also made in the US. And now, when you want to order the replacement fill valve for virtually any Toto toilet directly from Toto, they are going to steer you to a valve called the TSU99A.X, which is their new universal replacement fill valve, regardless of what fill valve came with your toilet. That, too, is a version of the Korky 528MP, the Korky version of which you can get at Lowe's. (There may be some slight differences in the valve designed for Toto, but it is effectively the same thing.) All of this stuff is Made in the US.
That said, Toto makes some models only in the US, and some models in various places, like Vietnam and Mexico. They are the world's largest plumbing fixture company, so naturally they have plants all over. I have a tank made in the US and a tank made not in the US. I have a bowl made in the US and a bowl not made in the US. Interestingly, the US tank wasn't delivered with the US bowl. The quality on all of them was excellent, indistinguishable one from the other. Nothing came from China, except that one of the Drakes (and my Carlyle) came with that Voreto valve, which was designed (and patented) by two Toto engineers and built by a company called Voreto in Xiamen, China. I disposed of the Voreto valve in my Drake, which made an annoying chirping sound, and replaced it with a Korky 528T, and now it shuts off just like the Drake that came from the factory with the 528T, i.e. smoothly, with no chirp. From what I can tell from the patent application, Toto had some design goals with that Voreto valve along the lines of reducing customer complaints and confusion, making it more idiot-proof to maintain, and making it shut off more affirmatively. I understand why they want to go there, but I think they have just induced a different set of complaints. But, hey, it's a toilet fill valve so it isn't the end of the world in any event.
Otherwise, the design mandate on the Totos was for a long time to keep it gimmick-free, simple, and of high-quality. I'm not sure that the marketing people aren't pushing away from that "gimmick-free" part a little bit, but we will see as this next round of toilets comes on-line. Is that new flush valve a real technological advancement, or is it a gimmick? Only use will tell.
Bottom line, you can look on Terry's sales page and see which toilets are all made here in the US, and even if you get something like the Drake, you can always ask at your plumbing supply if they have a tank and a bowl that have "Made in the US" on them, or if they can secure you one. Most other brands, like American Standard, Crane, Kohler and others (except Mansfield), build most of their toilets in Mexico. And the Fluidmaster 400A valve, the mainstay of US toilet fill valves, is made there as well.
Hope this helps.
