The Reality of Japan's Shortest Subway: Is the Crowding Solved?

ABOUT THIS VIDEO
Why does the Yokohama Municipal Subway Green Line, one of Japan’s shortest subway routes, struggle with such intense crowding?
In this video, we explore the unique engineering and history behind this 13.1 km (8.14 miles) line. Built as a linear motor system to navigate the steep gradients of Yokohama’s hilly suburbs, the Green Line uses smaller carriages and narrower tunnels to reduce construction costs.
However, these specialized standards created a major capacity challenge during rush hour. We investigate whether the recent transition from 4-car to 6-car trains has truly solved the congestion at Hiyoshi Station and look into the architectural constraints that make shifting passenger flow so difficult. Join us as we dive into the reality of Japan’s specialized urban transit.
