Tetrapod, big and beauty breakwater in Japan
Hit the beach anywhere in Japan, and you are likely to see endless piles of tetrapods — enormous four-legged concrete structures intended to prevent coastal erosion. By some estimates, more than 50% of Japan’s 35,000-kilometer (22,000-mi) coastline has been altered with tetrapods and other forms of concrete. Critics, who blame the tetrapod invasion on decades of excessive government spending designed to bolster the construction industry, argue that in addition to posing a danger to swimmers, surfers and boaters, tetrapods actually accelerate beach erosion by disrupting the natural processes that shape the coastal environment. Meanwhile, others have developed an aesthetic appreciation of the tetrapod landscape, as evidenced by a host of stunning Japanese tetrapod photos on Flickr.

I find the tetrapods an eyesore. They look terrible and they collect a ton of trash that no one ever cleans up. I live in Okinawa and an incredible amount of formerly beautiful coastline has been lost to tetrapods and other concrete atrocities. It’s not just the coastline that is being destroyed with concrete structures; pretty much the entire southern half of Okinawa is pure concrete with the occasional tree thrown in. It’s quite hypocritical that Japan is making a big deal over the proposed Henoko air field for the US military because of environmental concerns when the Japanese have no problems dumping concrete in to the ocean elsewhere with no regard to the environment where the US military is not involved.
