Tokyo is not only a large but vertical city. Dozens of different services intertwine in upper and lower levels: convenience stores, restaurants, bars, shops, parking lots, sports or driving schools and certainly transport facilities are stacked up too infinity. It is no wonder that many films feature such overlapping layouts as a concept of highly populated future cities.
David Mitchell puts it this way in his book number9dream: “Tokyo is too close up to see, sometimes. There are no distances and everything is above your head – dentists, kindergartens, dance studios. Even the roads and walkways are up on murky stilts. An evil-twin Venice with all the water drained away.”
Whereas Venice is a showcase for beauty one may find debatable however in fact, many former open rivers in Japanese cities have been regrettably used as main lines for elevated motorways due to lack of space and now often have a very limited attractiveness to while away one’s time.
Nonetheless they are a good motif in the right setting.
