Workers Cleaning a Japanese Bullet Train In Only 7 Minutes

Japan’s bullet train or shinkansen has long embodied the miracle of the country’s progress and efficiency. But it’s not just the trains that are quick.

A short video showing an army of cleaners clearing the cars in a record time has gone viral.

The clip, created by the American journalist Charli James, shows the cleaning crew diligently wiping the trays, sweeping the floor and clearing the seats.

Each worker covers one 100-seat car, and takes 12 seconds to clean a row. They only have 7 minutes before the train must take the next set of passengers.
