A little over 4 years ago, I had the pleasure of riding on this rather handsome tram in Kagoshima, southern Japan.
This is public transport rather than tourist, with my wife and I being the only foreigners on board. We had been briefed on how to use it. Boarding is at the rear, disembarkation via the front door. At each stop, the driver stands and turns to face the passenger cabin to his rear, with a ticket machine in front of him at the hatchway. He collects fares (or inspects a pass in our case), issues a ticket, bows and says "ありがとうございました", or "Arigatōgozaimashita", the Japanese form of "Thank you" used when an action is complete. I had learned that, but didn't know the correct response. When my turn came, I bowed in response and said "Cheers, Drive!", which was thankfully acceptable.
It was spotless, probably cleaned by the driver himself if needed.
