Japan’s Treasure Trove: Discovery of 230 Million Tons of Rare Minerals to Boost EV Industry
Japan has made a groundbreaking discovery that could shape its future as a leading player in the electric vehicle (EV) industry. Researchers have found a staggering 230 million tons of rare minerals on the seabed near Minami-Tori-shima Island. These valuable resources include cobalt, nickel, copper, and manganese, all essential components in the production of EV batteries and advanced technologies. This find could potentially earn Japan billions while securing its position as a self-reliant, technology-driven nation.
What Makes This Discovery of Rare Minerals So Important?
The discovery, revealed through a study by The Nippon Foundation and the University of Tokyo, uncovered 610,000 metric tons of cobalt and 740,000 metric tons of nickel—enough to meet Japan’s domestic cobalt needs for 75 years and supply nickel for over a decade. Both materials are crucial for making lithium-ion batteries, which power everything from electric vehicles to renewable energy storage systems.
But this isn’t just about numbers. These minerals are found in dense manganese nodules, scattered over an area of 10,000 square meters, lying 5,200–5,700 meters below the ocean’s surface. What’s fascinating is that these nodules formed over millions of years as metals dissolved in seawater bonded with biological material, like fish bones.
How Was It Discovered?
The breakthrough stems from a series of detailed seabed surveys conducted between April and June 2024. Using remotely operated underwater vehicles, experts explored 100 sites in Japan’s exclusive economic zone, situated around 1,200 miles from Tokyo. The vehicles descended thousands of meters below the surface to detect and analyze the mineral-rich nodules.
The area had initially drawn attention in 2016 when researchers found similar deposits, even tied to fossils like Megalodon shark teeth. But it was only with advanced exploration technology and large-scale collaboration that the massive scale of the mineral deposits was confirmed.
Environmental and Economic Impact
Mining the seabed at such depths raises questions about environmental sustainability. However, researchers, led by Professor Yasuhiro Kato of the University of Tokyo, plan to minimize ecological disruption. The team intends to extract 3 million tons annually using specialized mining vessels by 2025. Their goal is to balance development with environmental care while creating a framework for large-scale commercial production.
By tapping into these vast mineral reserves, Japan can reduce its reliance on other countries, particularly China, for critical EV materials. This could stabilize the country’s supply chain, lower costs, and ensure that Japan’s burgeoning EV industry remains competitive in the global market.
A Boost for Japan’s Economy and Innovation
The discovery doesn’t just promise economic gains—it represents a leap forward for Japan’s ambitions in technology and science. The Nippon Foundation and its partners aim to develop eco-friendly products and next-generation energy infrastructure. This discovery could give rise to new industries, from resource mining to advanced manufacturing, solidifying Japan’s status as a leader in sustainable innovation.
As Japan moves forward with plans to commercialize these deposits by 2026, it’s clear that the implications extend far beyond financial profits. This find positions Japan to lead in addressing the world’s growing demand for clean energy and sustainable technology, making it a shining example of how science and industry can collaborate for transformative results.
In the words of the University of Tokyo’s press release:
“Ultimately, we expect our research outcomes to establish Japan as a true science, technology, and ocean-oriented nation, creating a domestic supply chain that drives growth and innovation for generations to come.”
This remarkable discovery is not just about unearthing minerals—it’s about paving the way for a sustainable and self-reliant future.
