Survey begins to assess remote island for nuclear disposal site

Japan's waste management organization will carry out a literature review on the geology of Minamitorishima, located nearly 2,000 kilometers from Tokyo, to determine its suitability as a nuclear disposal site.

Minamitorishima lies in the Ogasawara Islands. A literature-based geological review will begin to judge whether the remote site could host nuclear waste.

The step forms an early part of Japan's efforts to manage radioactive waste.

No further timeline or next actions have been announced yet.

Japan has identified an enormous underwater rare earth deposit 6,000 meters deep near Minamitorishima, the remote Pacific atoll central to its accelerated deep-sea mining plans. Detailed in a recent WIRED report, the find—building on equipment installation earlier this year—bolsters Tokyo's drive for independence from Chinese supplies of these critical manufacturing materials.

Japan plans to start a Minamata disease survey on residents along the Shiranui Sea coast in Kumamoto and Kagoshima prefectures as early as this year. The survey marks the first under a special law that took effect in 2009.

China's Ministry of Natural Resources has published an atlas from two decades of marine geological surveys, mapping the location, concentration, and distribution of dozens of elements in seabed sediments, including rare earths, iron, manganese, and copper. State broadcaster CCTV reported the atlas as a 'master navigation map' for marine development and conservation, based on over 20,000 observation points. Researcher Dou Yanguang from the Qingdao Institute of Marine Geology said it enables precise targeting of resources and identification of sensitive ecological zones.
