Dugong swimming in the waters around Henoko, Nago City, Okinawa Prefecture = September 2011 (from the report of the Okinawa Defense Bureau of the Ministry of Defense)

Some members of the Ministry of Defense Experts’ Council, which advises on environmental measures in the construction of a U.S. military base in Henoko, Nago City, Okinawa Prefecture, have posted a paper in an English scientific journal stating that the dugong in Okinawa was “extinct in 2019.” It turned out on the 27th.

The content is inconsistent with the latest survey results of the Ministry of the Environment, which allegedly confirmed the traces of dugong. In addition to questioning the dissertation, environmental groups have expressed concern about whether appropriate discussions will be made when considering the impact of construction work on dugongs and conservation measures at a meeting of experts.

The paper was submitted by a group of five domestic researchers. The first author, So Kayane and Professor of the University of Tokyo, are members of the Environmental Monitoring Committee, which is set up by the Okinawa Defense Bureau of the Ministry of Defense and provides scientific advice on environmental conservation measures.
