Video from Yokobori weird pinnacle in Narita Airport

Narita Airport had the strictest and most cautious securities in the world before the 911 tragedy in 2001 because of the numerous skirmishes brought by protesters partly associated with some left-wing extremists which attempted to terror especially in 1970s. Formerly, They surprisingly had several stringent security gates in several spots with body-frisking, ID confirmation and luggage claims those were conducted not only for the passengers but also the visitors entering boarding gates to secure the airport. 

The long-time and unsolved conflict between Airport and some protestors is elaborated by the anonymous editors in Wikipedia in English...as Sanrizuka Struggle.  Hereunder, I do not intend to express or insist which I am for or against the problems politically. Thanks so much for understanding.  

In this video, there are some uncanny and obstructive pinnacles in the airport which was not the property of airport or not built by the constructors. That's one of symbols or ,as they called,  surveillance gazebos of protesters against the airport. Those were also functioned as the obstacles for airplanes which possibly hamper the departures and landings. Therefore, the tower is the property of veteran activist because he or she adamantly defies to evict. 

Because of the human rights for their livelihoods of activists, the subterrestrial tunnels that leads to their homes or properties were constructed.  Some adventurous people interested in the pinnacles and journalists often visited the weird carbuncle fortress. They often tended to see the security guards who are in charge of surveillance to activist and have to be asked some investigations what are the purposes to visit to identify whether he or she is activist or not. 

By the way, honestly, the scenes from pinnacles are definitely eerie, uncanny and unfriendly but so thrilling and exciting, right? Airplanes are cool and spectacular but unfortunately noisy and windy for people to live with...moreover, I felt some nondescript isolation in the horizonal area with asphalts in Narita...which is imaginably different from the "completely concreted and shunned" Super Max prison in USA...
