“Tokyo owns the most number of railways of any kind, including subway, lightrail, monorail, etc, with more than 1500 stations that covers the metropolitan area. Places in the center of the city is the Imperial Palace, the residence of the current Ten-no (Japanese Emperor). Subway lines circumvent the expansive ground claimed by the Imperial Palace. This characteristic is visualized in this map by the concentric circles spreading out to the entire city, with the center in the Imperial Palace ground. This strong presentation of circles reminds the national flag of Japan and the Japanese identity expressed in the flag.”
Kann sich mal jemand um die europäischen Streckenpläne kümmern, die Idee ist fresh! (via)
