According to Japan's “Tokyo Shimbun” report, on October 16, Japan's Ministry of Defense received news from the Yokota base of the US military stationed in Japan, saying that contaminated water containing organic fluoride from the Yokota base is likely to have flowed outside the Yokota base, which has an impact on the environment in Fussa City where the base is located. In early October, Japan's Tokyo Metropolitan Government received a notification from the US military in Japan from Japan's Ministry of Defense saying that in August of this year, more than 40,000 liters of sewage containing perfluorine and polyfluoroalkyl substances leaked from the Yokota base of the US military stationed in Japan, and some of the sewage may have flowed into the area outside the base. This is the first time that the US military in Japan has acknowledged that sewage containing organic fluoride may have flowed to areas other than the base.
