Historically, Japan has relied heavily on these imports, which has created a palpable sense of urgency for the nation to find a solution. After thorough exploration, Japan recently discovered an invaluable resource: <u>a massive deposit<\/u> of rare earths beneath the ocean. As a result, the country has announced plans to commence extraction.<\/p>\n<p>  <!-- BREAK 1 --> <\/p>\n<p><strong>January 2026<\/strong> marks a pivotal date, as Japan plans its first test extraction phase, according to <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/asia.nikkei.com\/Spotlight\/Supply-Chain\/Japan-to-begin-extracting-deep-sea-rare-earths-next-year\" target=\"_blank\"><u>Nikkei Asia<\/u><\/a>. Initially set to begin this year, the project faced delays due to the late delivery of the required equipment. A vital 12,000 million yen (approximately 71 million euros) duct manufactured in the United Kingdom is essential for accessing the deposits located at depths of \u00a05,500 meters\u00a0.<\/p>\n<p>  <!-- BREAK 2 --><\/p>\n<div class=\"article-asset article-asset-normal article-asset-center\">\n<div class=\"desvio-container\">\n<div class=\"desvio\">\n<div class=\"desvio-figure js-desvio-figure\"><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p><strong>The Chikyu<\/strong>, part of the Japanese Marine-Terrestrial Science and Technology Agency (JAMSTEC), will spearhead this extraction effort. This specialized drilling vessel has previously conducted tests at depths of \u00a02,500 meters\u00a0 along the coast of Ibaraki Prefecture. The new challenge lies in drilling more than double that depth\u20145,500 meters. Should they succeed, it will mark a groundbreaking milestone as rare earths have never been extracted at such extreme depths.<\/p>\n<p>  <!-- BREAK 3 -->  <\/p>\n<p>During the first extraction phase, the Chikyu aims to pull up \u00a035 tons of mud\u00a0. Each ton is estimated to yield around \u00a02 kilos of rare earths\u00a0, translating to a potential total of \u00a070 kilos\u00a0 in the best-case scenario.<\/p>\n<p>  <!-- BREAK 4 --><\/p>\n<p><strong>A key discovery<\/strong> came nearly a year ago near Minami-Torishima Island, located approximately 1,900 kilometers southeast of Tokyo. As this site lies within Japan&#8217;s exclusive economic zone, the extraction rights belong to Japan. Among the minerals present, \u00a0gadolinium\u00a0 plays a crucial role in the nuclear industry, while \u00a0dysprosium\u00a0 is primarily used in electric vehicle magnets. Furthermore, the site is rich in \u00a0manganese\u00a0, \u00a0cobalt\u00a0, and \u00a0nickel nodules\u00a0, all vital components for battery production.<\/p>\n<p>  <!-- BREAK 5 --><\/p>\n<p><strong>The potential quantity is both unclear and decisive.<\/strong> Initial estimates suggested the site contains about \u00a016 million tons\u00a0 of rare earths, placing Japan third behind \u00a0China\u00a0 (44 million tons) and \u00a0Brazil\u00a0 (21 million tons). However, a recent <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/tnfsa.nippon-foundation.or.jp\/news\/2071302\" target=\"_blank\"><u>University of Tokyo analysis<\/u><\/a> posits that this number could be as high as \u00a0230 million tons\u00a0. If accurate, Japan would surpass China, positioning itself as the leading reserve holder of rare earths globally.<\/p>\n<p>  <!-- BREAK 6 --><\/p>\n<p><strong>Independence<\/strong> has been a key motivation for Japan\u2019s push into extracting these essential minerals. The journey to autonomy began in 2022, as the nation aims to reduce its reliance on foreign sources. Currently, Japan imports \u00a060%\u00a0 of its rare metals from China. To counter this dependency, the Japanese government has invested approximately \u00a06,000 million yen\u00a0 (around 42 million euros) in the initial extraction phases, making this a national priority.<\/p>\n<p>  <!-- BREAK 7 --><\/p>\n<p><strong>Friction<\/strong> between Japan and China is a growing concern, particularly given China\u2019s significant control over rare earth supplies. Recently, a naval fleet led by two Chinese aircraft carriers entered Japan&#8217;s exclusive economic zone near Minami-Torishima, a move that raised alarms. While Japan did not formally protest, officials stated they conveyed an &#8220;appropriate message&#8221; regarding the incursion. This incident highlights ongoing tensions and the strategic importance of rare earths in geopolitical discussions.<\/p>\n<p>  <!-- BREAK 8 --><\/p>\n<p>Image | <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/tnfsa.nippon-foundation.or.jp\/news\/2071302\" data-id=\"noopener, noreferrer\" target=\"_blank\">TNFSA<\/a><\/p>\n<p>In conclusion, Japan\u2019s groundbreaking venture to extract rare earths from the ocean floor signifies a monumental shift in its approach to resource acquisition. With the stakes so high, both economically and politically, the success of this project could reshape not only Japan&#8217;s energy infrastructure but also the global balance of power in rare earth resources.
