I never used a squat toilet until I moved to Osaka. They're sometimes the only choice, including at some work locations. When I first visited Japan, I still had my large intestine and just avoided any non-western toilet. (Nervousness, first time ignorance, and so on.)
I always feel so much better - more emptied, less stress on the guts, less mental stress anticipating the next urgency grip - so much more quickly after using the squats. I'm a bit sad they're disappearing here, even though they're often replaced with ridiculous bidet systems. (Heated seats, adjustable water settings, fans, deodorizer, whitenoise water sounds to reduce any embarrassment and encourage flow, autoflush, autoclean, usb outlets, clocks. Surprised I haven't seen one that's a wifi hotspot . . . )
I have no idea how widely people in this community use Squatty Potty-type stools or anything else to get similar effects. Very curious what this community has experienced, including your thoughts if you've never tried it.
