It is truly amazing how far they have advanced in toilet technology especially with your 1960's vignette added on.
During the same time period, they've advanced from open sewers to toilet seats which heat your derriere, clean your backside, rinse out your anus and even (if you are willing to pay the price) analyzes your urine. And, of course, from open sewers to high grade closed piping.
We, by contrast, use basically the same toilets we used back in the 60's with slight design changes and slightly lower water usage and from metal to plastic piping.
LOL, no kidding. As a kid, it was a real culture shock going over there.
When I first saw one of those toilets that was a ceramic hole in the ground with foot pads on each side...wtf????
Really interesting place.
The newer low water usage stools with 4 inch flapper valves flush first time every time. Add a Bidet lid and you have a good system. Japan judges wealth by the Bidets in use.
I’ve advised my beloved if (more like when) the main bathroom is renovated it’s going to be done to my specifications and it *will* include a bidet. The Japanese have the absolute best plumbing and I hope to have installed pieces manufactured over there.
My beloved short changed the last renovation on the main bathroom which is the one I use and it still irks me.
LOL
