Translation

Japan's shinkansen, when it arrives at Tokyo Station, departs again after 12 minutes.

During that time, they make the whole inside of the train clean in just 7 minutes.

A team of 22 people divide up the 16-car train and clean it.

Each person takes charge of one car, about 100 seats.

They sweep the floor, turn the seats to face forward, and pick up forgotten items too.

Before starting and after finishing, they bow.

What is the "7-minute miracle" on the Shinkansen?

Watch a Shinkansen pull into Tokyo Station and you will see something that has become a small legend among travelers: the train is scheduled to turn around and leave again after only 12 minutes. Passengers take about two minutes to get off and three to board, which leaves the cleaning crew just seven minutes to reset the entire train. That routine is known as the "7-minute miracle".

The numbers behind it are simple. A 16-car train has roughly 1,300 seats. A team of 22 cleaners meets it on the platform, and each person takes one car — about a hundred seats. In those seven minutes they rotate every seat to face the direction of travel, wipe tables and windows, sweep the floor, check under and between seats for forgotten items, change the headrest covers and sort the trash before carrying it off. Every step is timed to the second, and the crews rehearse so that there is no wasted movement.

What visitors remember most, though, is the choreography around the work. The team lines up on the platform and bows to the arriving train, and bows again to passengers when the job is done. That mix of speed and courtesy has been featured by overseas media and studied by foreign railway companies and business schools as an example of Japanese teamwork.

This article comes in six versions, one for each school grade from 1 to 6, each with furigana and full Vietnamese and English translations.

How many people clean a Shinkansen and how long does it take?

A team of 22 cleaners handles one 16-car train with roughly 1,300 seats, so each person is responsible for one car of about a hundred seats. The work takes about seven minutes and is timed to the second. The team bows to the train when it arrives and to passengers when the cleaning is finished.

Why six school grades, and not N5–N1?

Because that is how Japanese children learn to read. Japan's Ministry of Education fixes exactly which character belongs to which grade — so "grade 3" is a boundary you can verify, not a feeling. Every article here is machine-checked: if a single character sits above its grade, it is not published.

The result: you never hit a character you have not learned. That is the whole reason this product exists.
