Hello,

I'm about to move back to the states from Japan, and there's no way we can give up these amazing toilets.
So I plan to bring back a Toto or INAX entire toilet/washlet combo.

-I'm aware of the electrical supply differences and requirements and have a solution there.
-I also know that the supply fittings are US standard so know issues there. I know some are designed for supply valve on the port side instead of starboard like in the states. A problem which is solvable.
-Rough-in according to the spec sheets is adjustable on the Toto models and at seems to cover 12"-14" without issue.

Is there anything else I may be overlooking?
How about the drain flange itself? Is shape or diameter a concern,or does wax solve everything?

These toilets are much, much cheaper in Japan so the lack or warranty and perhaps direct replacement parts from Toto USA is justifiable to me. Shipping will also be free, too!

Shipping something like a toilet, while maybe 'free', is still with risks...the thing is made of porcelain, and heavy. Not something typically dealt with in household goods even with the factory packaging.

If you have the owner's manual, you could compare part numbers between that one and the equivalent in the US from the www.totousa.com website. Isn't most of Japan using 110vac? If so, that shouldn't' be an issue at all other than maybe the plug.

I think more trouble than worth it. What is so amazing that you can't get here?
But, hey, you tell us when you get them.
There is a thread on this forum of a person who brought a Japanese Neorest over and the unique rough in plastic fitting and insides match ups were different.

Thank you so much for mentioning, I missed that thread in my search. It's exactly the info I need!

Thanks for your concern, but shipping in by sea container with all the rest of my household items.
FYI: Japan grid is all 100VAC, with 60Hz service in the west at 50Hz in the east. The plugs are the same as the US standard.
A Japanese toilet will all be rated for 100VAC 50/60Hz.

And yes, I feel $12000 is worth the trouble. That's the price difference between the top of the line Neorest NX from USA Toto vs the equivalent in Japan.

If they're delivering the container direct to your new place and you can unload it, and the same on the other end, probably okay. But, if it is being unloaded and loaded, and stuff trucked to where the container is, those extra steps do not bode well for something like a toilet. The more times it is handled, the more likely there is for damage to occur.

The power may not be an issue as many 'universal' power supplies can handle that range. If it's a fixed PS, it may be an issue. It's also possible that there's a jumper(s) or switches on the PS board that can be changed to adapt the PS to the US standards. Normally, the 50/60Hz isn't an issue, but it can be. IT costs more to make it more universal, but it also means inventory is cheaper, so it's a trade-off. Some have a clock or timer function, and depending on how it's built, the 50/60Hz can make a difference in the time-keeping. If it's got its own crystal, no problem, if it's using the Hz, the timing will be off.

32000 posts, wow! Thanks for all your concerns, but when you do an international move like this, you'll have insurance in case things break. As I mentioned I have the electrical considerations sorted already, but you're on the right track.

I'm really hoping the guy in the other thread comes back with his conclusion if the US market unifit worked in his JP toilet or not, or how much modification it took.

You know USA power is 120V. I''m no electrician but 100V. seems not rated high enough.
Here in Calif. Toto Neorest NX1 is about $8,820. USD NX2 is definitely an eye opener at $17K.
What equivalent are they selling in Japan that you can buy?

It can be risky to ship something as heavy as a toilet, even if it's 'free'. We are talking about something made of porcelain. Porcelain is not something that is normally packaged for shipping in household goods.

I think in the other thread the issue was attempting to use the US unifit on the Japanese version of the neorest.. so ss long as it comes with its own Unifit you should be able to easily adapt that to a closet flange in the US. You might have to move the location of the drain. I had to move the drain for a German made duravit before they made adapters for our 12" rough in.

getting factory service on your neorest should be an interesting phone call!

I don't think they do have any switches on the board to change any settings. I see the insides of a Lot of neorest. The only settings that can be changed are in the remote control which reprograms settings in the Neorest.

Hi, just wanted to add a bit of information that I had on this topic in the hopes it helps someone else. I brought the Toto Apricot bidet seats with the auto flush option from Japan and was able to install them on a Toto Drake and Ultramax elongated toilets here. No changes were really needed on the plumbing side aside from having to add a tee to split the water off. The connection size was compatible with imperial sizes used here. I added a power transformer to step down the power but it might not be necessary as the voltage is somewhat close. The only part that was a bit iffy was I needed to trim the auto flush plastic around the lever a bit to better fit into the flush lever hole a bit. I think if you take a look at the Toto s450 or similar N. American models available and find a similar Toto bidet model in Japan you should be ok. I remember finding a compatibility chart for the s400 bidet which was very similar to the Apricot model in Japan which gave me confidence this could work. The only other downside is the buttons are all in Japanese. This was 10 years ago for me so ymmv. Happy to share photos or anything to help.

The seats would be much easier to adapt than a Neorest
