I don't live in Japan, but I don't remember being in a train where there wouldn't be at least two people from the staff in uniforms. Could you explain what you have in mind? Are there trains without drivers or without people checking tickets?

The skytrain in Vancouver, Canada, has nobody from staff and it's fully automated. Really cool.
