I didn't see it, but saw the listing in the TV guide, and from that summary it sounded like all the other 'isn't Japan weird' TV programmes there have been over the years - most of which would be completely unrecognisable to anyone Japanese.
It's like doing a programme on the UK and only visiting Hooters on a stag night, a Dr Who fan event, a gypsy wedding and a night at the greyhound races, and saying this is what life in England is like...
I lived in Tokyo for 11 years, and never went to a host bar, never saw a used-knicker vending machine, etc etc. Yes, I'm sure all those things do exist, but they are hardly mainstream.
I suppose that kind of programme is OK purely for entertainment purposes, but since most people in the UK will never visit Japan, it's a shame they get a seriously warped idea of the place.
