Here's the problem: modern bidets require electric power to work--and that means you need an electrical outlet near the toilet. Completely uncommon in the USA, you see it standard (pun not intended!) in Japanese homes.

The ones I’ve seen in the US don’t require electricity at all.

The Japanese like to make things electronic so I wouldn’t be surprised at all if they needed electricity to operate the ones in Japan.
