Our Japanese colleagues would be utterly horrified at this behaviour and there was never a ticket inspector to be seen anywhere because honour and honesty are basically core values in Japanese culture.
Yes the fare adjustment system is still in place.
Tickets are regularly and consistently inspected on long-distance services in Japan, and stamped.
