This just seems like the less-dramatic Japanese version of that North Korean woman who tells those ridiculous lies about how bad North Korea is on podcasts
>Oooh in North Korea it is so bad
>The government has a poop tax and they come to collect your poop and if you do not give them enough they will shoot you and cut your body open and scoop the poop out of your body and then they will shoot your dog and scoop the poop out of HIS body because they are making things out of the poop
>but the things they make out of poop don't work and when they don't work the poop commissars are lined up and shot with tank cannons and then people have to go pick the poop out of the blown up body parts and give it to the next poop commissar

Japanese ex-pat youtubers who exaggerate about long working hours, sexual deviancy or the sex industry, or workplace bullying are just doing a more believable version of that. It's good for business to play up "Weird thing, JAPAN" stories to get views from Westerners.
