The Ryukyu Shimpo reported on 14 September 2021 that the coral that was transplanted by the government of Japan was crushed into small pieces, and put back together using adhesive. This method has been decried by Indigenous peoples as well as environmentalists for the harm it does to the coral.
Japan transplanted coral from Oura Bay at Henoko, Okinawa in order to build a new U.S. military base. Uchinanchu, the Indigenous Okinawan people, have strongly opposed the move. The location is home to an ancient coral reef filled with hundreds of rare and endangered species, including the Okinawa dugong.
The above map is from the same Ryukyu Shimpo article. The orange squares with black stripes show the locations where the coral was moved. The grey, white, and pink areas are where the military base is planned to be built.
