You have to take into account that Japanese do not place nearly as much emphasis on human-to-human relations as much as the west does. Things like kaiten sushi (revolving sushi) and advanced vending machines are popular because customers don't have to interact with another human being.
A particularly advanced line of vending machines that recorded and recommended drinks to you even garnered unprecendented levels of love from its customers because they felt it was more relatable and comforting than an actual waiter.
Pachinko parlors being a space where it's just you and the machine in front of you (and all the noise around you) is thusly a positive factor rather than a negative one.
In general, Japanese just don't like dealing with humans if it can be helped. Interacting with machines is by far preferred.
