It is one of Japan's largest subway stations, serving four Tokyo Metro lines (Marunouchi Line, Tozai Line, Chiyoda Line, Hanzomon Line) and the Toei Mita Line, but its interior is labyrinthine and complex. This video explains the surprising historical background behind why the Marunouchi Line bypassed Kanda Station and instead passed through Otemachi. We'll also uncover hidden secrets about Otemachi Station, such as the chaotic corridor structure caused by the Marunouchi Line tunnel that juts out onto the Tozai Line platform, the interior boundaries that blatantly change depending on the management company, and the integrated structure of the Chiyoda and Mita lines brought about by the presence of the Imperial Palace, an oasis in the city center. From the latest station facilities that have been upgraded through renovations to a rare train car that is nearing retirement, we'll reveal the full story. ●What you'll learn from this video 5 reasons why the Marunouchi Line was rerouted through Otemachi, avoiding Kanda Station The unique corridor structure created by the Marunouchi Line tunnel that squeezes the Tozai Line platform Why the Chiyoda and Mita lines were built as an integrated line The differences between management companies are clear at a glance!
