The 12 months 2010 was a reckoning for Japan’s financial safety.
On September 7, the Chinese fishing trawler Minjinyu 5179 refused an order by Japan’s coast guard to go away disputed waters close to the Senkaku Islands, that are recognized in China as Diaoyu. The vessel then rammed two patrol boats, escalating a decades-long territorial feud.
Japan responded by arresting the captain, Zhan Qixiong, below home legislation, a transfer Beijing thought-about an unacceptable assertion of Japanese sovereignty. Amid mounting protests in each nations and the collapse of high-level talks, China reduce exports of uncommon earth components to Japan, which relied upon its geopolitical adversary for 90 p.c of its provide. The transfer reverberated all through the world economic system as corporations like Toyota and Panasonic have been left with out supplies essential to the manufacturing of every little thing from hybrid vehicles to non-public electronics.
It wasn’t lengthy earlier than Japan gave in and let Qixiong go. The disaster, which garnered worldwide consideration, grew to become a catalyst for Japan’s push to safe a dependable provide of vital minerals. “That was the turning point,” mentioned Takahiro Kamisuna, a analysis affiliate at the International Institute for Strategic Studies in London.
Fifteen years later, that reckoning has solely deepened.
China nonetheless supplies 60 p.c of Japan’s vital minerals, a reliance that has grown riskier as Beijing asserts its place as the world’s dominant provider. Last month, Japan took a daring step to interrupt that dependence when it launched a five-week deep-sea mining test off Minamitorishima Island. A crew of 130 researchers aboard the Chikyu — Japanese for “earth” — will use what is basically a robotic vacuum cleaner to gather mud from a depth of 6,000 meters, marking the world’s first try at extended assortment of minerals from nice depths.
Seabed mud off the coast of that uninhabited island, which sits 1,180 miles southeast of Tokyo, is wealthy in uncommon earths like neodymium and yttrium — distinct from the potato-shaped polymetallic nodules usually related to marine extraction. Such supplies are important for electrical autos, photo voltaic panels, superior weapons techniques, and different expertise.
The expedition, which is anticipated to finish February 14, is being led by the Japan Agency for Marine Earth Science and Technology, which didn’t reply to a request for remark. It comes three months after the nation signed an agreement with the United States to collaborate on securing a provide of vital minerals. It additionally propels Japan to the forefront of a rising debate over how far nations ought to go to safe these supplies. Deep-sea mining “is not a new thing,” Kamisuna mentioned, “it’s just gaining more attention mainly because of geopolitical tensions.”
The trawler incident highlighted a vulnerability that successive governments vowed to alleviate. Many criticized then-prime minister Naoto Kan of the nation’s center-left get together for capitulating to China, however he pledged to by no means once more let Japan’s industrial future hinge on a single provider. His successor, Shinzo Abe of the center-right get together, was extra aggressive and noticed vital minerals as not simply an financial subject, however a matter of nationwide safety that should be addressed even when it meant exploiting the deep sea.
Establishing a home provide could assist Japan attain its aim of reaching carbon neutrality by 2050, a excessive precedence for Yoshihide Suga, who succeeded Abe. Although Prime Minister Sanae Takaichi, an Abe protégé who assumed workplace late final 12 months, helps the 2050 timeline, she has mentioned the transition should not danger Japan’s industrial competitiveness and vitality stability.
Takaichi has proposed slashing subsidies for large-scale photo voltaic initiatives or batteries, largely as a result of a lot of that expertise is imported from China. Instead, she has hailed nuclear power as the path towards carbon neutrality. With the mining experiment unfolding in the Pacific, Takaichi hopes to safe a strategic reserve of minerals to guard key industries.
But Japan doesn’t face an either-or alternative, mentioned Jane Nakano, a senior fellow at the Center for Strategic and International Studies in Washington, D.C. “Energy security and energy transition are closely tied,” she mentioned.
“To me, it’s much more about the pace, not so much the direction,” mentioned Nakano, who has labored for the U.S. Department of Energy and for the vitality attaché at the U.S. embassy in Tokyo. “I don’t find Takaichi’s way of framing this dual challenge — energy security and decarbonization — unique to Japan. A lot of G7 countries are starting to recalibrate again, so they do have to think about international competitiveness. Direction-wise, [Japan] is just aligning itself with the political establishment and the industry.”
Unlike China, Japan lacks the sedimentary geology related to uncommon earth deposits, requiring it to look towards the waters inside its unique financial zones. Under the United Nations Convention on the Law of the Sea, Japan has the proper to use the sources inside 200 nautical miles of its shoreline, which incorporates the atoll island of Minamitorishima.
Although the minerals to be discovered there lie almost 20,000 ft beneath the floor, proponents of digging them up argue the problem of extracting them and the price of refining them is justified by mounting geopolitical pressure. With Takaichi’s recent political jabs at Beijing, China has begun choking off its exports to Japan. Nakano mentioned Japanese officers appear “confident” in the end result of the experiment. “They’ve determined that it merits to have this demonstration of technologies and equipment this time around,” she mentioned.
Japan’s foray into deep-sea mining comes amid mounting concern about the ecological price of such expertise. Scientists and environmental teams warn that marine extraction is racing forward of our understanding of the impacted ecosystems. They are significantly involved about sediment plumes, noise and lightweight air pollution, and harm to habitats and meals webs, noting that scars left by gear could render the seafloor uninhabitable for many years, even centuries.
“A tiny little nudge, and the whole seafloor is disturbed,” mentioned Travis Washburn, a marine biologist at Texas A&M University in Corpus Christi. He studies deep-sea environments and human impacts on marine ecosystems, and he has analyzed the waters around Minamitorishima Island and represented Japan at International Seabed Authority workshops. He believes that mining uncommon earths from mud could have the identical influence as mining nodules. “I think that they’re both pretty much going to destroy the habitat directly affected.”
Government officers insist the ecological impacts will likely be carefully monitored. But assessing them could be troublesome, as a result of the seafloor round the island, home to sea cucumbers, sponges, corals, and doubtlessly uncommon endemic species — stays the topic of intense research. Scientists worry these ecosystems could also be completely altered earlier than anybody assesses them. As with many extractive industries, Washburn famous, expertise is usually deployed earlier than anybody totally understands its environmental impacts.
Shigeru Tanaka, deputy director common of the Pacific Asia Resource Center, is an outspoken critic of deep-sea mining. He argues that the business as an entire disregards worldwide legislation and that exploiting the seafloor will hurt fisheries and trample upon the rights of Pacific Islanders who take into account the sea as sacred. (The Indigenous folks of the Mariana Islands have raised such considerations in opposing Trump administration plans to open the waters there to mining.) He additionally believes that some of the consultants concerned in Japan’s project “are not really taking seriously the risks to the environment and how irreversible it may be.”
Even some authorities officers have expressed concern. Yoshihito Doi of the Agency for Natural Resources and Energy has said Japan ought to mine solely “if we can establish a robust system that properly takes environmental impacts into account.”

It stays unclear what precisely is unfolding beneath the waves throughout this present test, however based mostly upon his expertise working with the Japanese authorities on related analysis, Washburn mentioned the high precedence will likely be assessing whether or not the expertise works. Researchers additionally will monitor how a lot materials the system can maintain and if the equipment can hold the sea mud contained with out releasing an enormous sediment plume on the seafloor or in the water column.
If Japan can efficiently deploy a 6,000-meter pipe that may suck up 35 metric tons of mud below excessive strain — about 8,700 kilos per sq. inch, or 600 instances the strain at sea degree — authorities officers say a broader trial, which can embrace polymetallic nodules, could start in February 2027.
One longer-term aim is to develop what’s known as “hybrid mining.” Because deep-sea polymetallic nodules sit atop the rare-earth mud round Minamitorishima Island, researchers are exploring whether or not each could be collected and separated in a single operation.
Kamisuna mentioned Japan faces one other problem: The vitality wanted to accumulate and refine a stockpile. “If we want to create a sufficient reserve for rare earth [minerals], either using domestic or export, a large amount of electricity is required,” he mentioned. “And the question is, What are we going to use, liquified natural gas or coal? What is the environmental cost?”
Using extra environmentally pleasant strategies of extraction and processing might be costly, he mentioned — which is one purpose many nations flip to China as a less expensive choice.
For now, Japan’s deep-sea mining experiment appears to have drawn little public opposition at dwelling, in contrast to in the United States and Australia the place environmental activists and Indigenous communities have pushed again towards such operations, significantly round the Pacific Islands. In the meantime, the nation’s test strikes ahead, whilst the implications of success, and questions on its long-term influence, stay unresolved.
“We are not prepared,” Tanaka mentioned. “My personal take is that by the time we are ready, when the technology and the science is set, I really do not think there would be a demand for it.”
