The cleaning crews who maintain Japan’s high-speed bullet trains have a mere seven minutes to make the interior of the train spotlessly clean for its next journey. Those seven minutes are carefully divided into different tasks to make sure everything gets done in the allotted time.
Another curious detail people often notice about these cleaners is the way they bow as trains are entering and exiting the station. While this act is generally thought to be a respectful gesture, the intended recipient of the bowing seems to be a matter of great debate, with plenty of conflicting opinions out there, even among the Japanese!
