Chronological stories from our trip to Japan will have to wait until I have more time, but I'll try to fit in an occasionally tidbit here and there.
Many people have heard of the really fancy Japanese toilets, the ones with heated seats and more buttons than a DVD player, including Cover-Up Sound, Wash, and Blow Dry. I haven't had the opportunity to try anything but the warm seat feature (especially nice in unheated bathrooms), but we'd certainly have one if they were readily available at a reasonable price in the United States. I suppose we could special order one for an outrageous sum, but they aren't that wonderful.
It would take not money, but a societal attitude change, to make another of the great Japanese toilets available in the United States: the "squatty potty." Nearly flush with the ground (pardon the pun), these toilets are particularly great for public places, as they are much easier to keep clean than the kind we are accustomed to. They are also surprisingly easy to use. Before I tried one, I couldn't picture using it successfully, but it's really no problem at all.
My favorite Japanese toilet is the kind in Janet's apartment. It's a "normal" toilet with one fabulous feature: the tank lid is a faucet/sink arrangement. Flushing the toilet causes water to pour out of the faucet for handwashing purposes; the water drains into the toilet tank and is used for the next flush. What an economical, ecological idea!
