Once I saw an online article in Japanese about Tokyo Station’s Dungeon . The title of this post might be a bit odd , but in reality it is about the underground passage from Tokyo Station to the entrance of the JR Keiyo Line Tokyo Terminus . The JR Keiyo Line Tokyo Terminus was opened in March 1990 , so it is newer than the other stations across Tokyo . The JR Keiyo Line is the train line that links Tokyo to Tokyo Disneyland and Makuhari Messe , both in Chiba Prefecture . This underground passage is also a way to go from Tokyo Station to the Tokyo International Forum on foot without the inconveniences of the outdoor weather . It is a 15 to 20 minutes walk from Tokyo Station to the Tokyo International Forum .
Tokyo Station , basically faces either the Marunouchi District or the Yaesu District . Tokyo Station has several entrances . The closest one to this underground passage is the Marunouchi Underground South Gate . Beware that this is an unmanned gate , with only automatic gates , if you’re using the Japan Rail Pass you might need to exit at the Marunouchi Underground Central Gate .
Marunouchi Underground South Gate
You can easily find the beginning of the passage by looking for the train wheels monument close to the Marunouchi Underground South Gate .
Past the train wheels monument go to entrance to the underground passage , which the red lights in it’s columns .
Not to the left . Straight ahead .
The JR Keiyo Line is color coded in red , hence the red lights in the columns .
Through this corridor , down the stairs .
Almost there . Down the slope .
Another view of the slope .
Before you get to the gates of the JR Keiyo Line , to your right side is the entrance to the Tokyo International Forum .
