Big cities in Japan, especially the Tokyo megalopolis, are built in a very vertical manner.
Even if skyscraper districts are quite rare, Japan likes to build very high towers and buildings. They are often divided like this: the first floors are open to the public, usually with diverse stores and then, there are several administrative offices for private companies. It is not surprising that the last floors shelters an observation deck, free or not, allowing visitors to admire urban zones at several hundred meters high.
Sometimes, it can be natural monuments that offer a point of view on the environment, most of the time high hills or mountains.
