Japan Built the World's Best Rare Earth Backup Plan. Now Everyone Wants to Copy It.

September 2010.

A Chinese fishing trawler rammed a Japanese Coast Guard vessel in the East China Sea, near the disputed Senkaku Islands. Japan arrested the captain. Two weeks later, ships carrying rare earth oxides to Japan stopped leaving Chinese ports.

No formal ban. No public announcement. Just silence at the docks.

Japan imported nearly all its rare earths from China back then. The metals that went into every hybrid motor, every guidance chip, every hard drive in Tokyo. All of it ran through Chinese ports. And all of it stopped.

So Japan did something most countries talk about but never do. They built a backup plan — stockpiling six months of supply and funding programs to pull neodymium and dysprosium from old electronics. They signed deals with miners in Australia, India, and Vietnam. They started hauling rare earth mud off the Pacific floor, 6,000 meters below the surface.

The playbook was simple. Japan's government agency Jogmec built a national stockpile and bought forward contracts. They gave Lynas, an Australian miner, the money to build a processing plant in Malaysia — on the condition that Japan got first call on the output. They funded magnet recycling at scale. And when scientists found rare earth mud on the Pacific seabed, they launched a program to bring it to the surface.

Sixteen years later, the results are in. Japanese dysprosium-iron alloy imports from China fell 82% in the first half of this year, compared to the same period in 2024. But Japan's factories kept running. Stockpiles held. Alternative suppliers delivered.

Today, the Critical Minerals Japan conference opens in Tokyo. Delegates from dozens of countries are here for two days. They want to study how Japan built the most diverse rare earth supply chain outside China. And they need to move fast. China's extraterritorial rare earth export controls and processing technology controls snap back November 10 — 62 days from now.

The conference covers deep-sea mining, magnet recycling, separation technology, and supply-chain deals. But the real value is in the hallways — the offtake agreements, joint ventures, and technology licenses being signed between panels.

The gap between Japan and everyone else is enormous. The U.S. imported 74% of its rare earths from China between 2018 and 2021. Europe is only now building its first real separation plants. Australia's Lynas is the only large non-Chinese producer, and Japan locked up much of its output years ago. Japan spent sixteen years and billions of dollars building redundancy at every link — from raw ore to finished magnet.

There is a lesson here. You don't build supply security by finding a deposit and hoping the rest works out. You build it backward — from the product your military needs, through every processing step, back to the ore. Japan figured that out when a fishing trawler took its entire supply offline. The question is whether the rest of the world can learn it without a crisis of their own.

$8B is moving in... are you?

So here's a number that got my attention.

Venture capital investment in U.S. crypto companies hit $7.9 billion last year.

Up 44% from the year before.

These are the smartest, most ruthless investors on earth.

And they're betting nearly $8 billion on blockchain.

This isn't some meme coin or flash in the pan crypto trend.

This is infrastructure.

Payment rails, settlement systems.

The digital plumbing that moves our money faster, cheaper, and safer.

The exact same thing that President Trump plans to force $382 trillion worth of financial assets onto by April of 2027.

And there's a single digital asset sitting at the center of everyone of these transactions.

It's the one token that every institution must hold to operate on this new system

That's why BlackRock, JPMorgan, Fidelity are already accumulating this fuel now (while it's on sale).

But I don't suggest waiting until the rest of Wallstreet catches on.

By then the big gains are out the window and you could be left fighting for scraps with everyone else.

DEALS

Europe Gets Another Link in Its Rare Earth Chain

Neo Performance Materials and France's Carester signed a deal last week connecting Carester's rare earth separation plant to Neo's European magnet operations. Carester is building a rare earth separation facility in Lacq, France, set to commission later this year. Neo makes magnets in Estonia. The deal creates a connected chain — feedstock to separation to finished magnets, inside Europe. Most European rare earth projects sit alone. A mine here, a lab there, no link between them. This one ties two emerging operations together. The chain is forming.

OPINION

Start With the Magnet, Not the Mine

Jack Lifton, co-chair of the Critical Minerals Institute, published a piece this week arguing that America's approach to critical minerals is backwards. The country keeps counting deposits and announcing grants. But a mine only matters if its output can reach a qualified buyer through a complete supply chain. Every stage — concentration, separation, metal, alloy, magnet, component — has its own technology and economics. Success at one step says nothing about the next. Lifton wants policymakers to start with one question: what does the military need to build? Then work backward to figure out which mines and plants actually matter. A deposit in the ground and a magnet in a fighter jet are connected by at least six industrial steps. Miss any one, and the chain breaks.

DEMAND

The Grid Needs Magnets Too

Rare Earth Exchanges flagged a new concern this week: America's electricity transition could pile serious demand pressure onto dysprosium and terbium — the same heavy rare earths already squeezed by China's export controls. Wind turbines need NdFeB magnets with dysprosium to handle high operating temperatures. Grid-scale generators need them too. As the U.S. shifts more power to wind and pushes electrification across transport and industry, magnet demand from the grid alone could strain supply well before 2030. Tellurium, used in thin-film solar panels, faces a similar squeeze. The defense sector is already competing for these materials. Now the energy sector is lining up behind it.

Pr
Praseodymium
The Other Half of Every Magnet

Praseodymium is the forgotten half of the world's most important alloy. It's almost always sold alongside neodymium as NdPr — the key feedstock for high-performance permanent magnets. The "Pr" does real work: it strengthens the magnet and fights corrosion. Without it, NdFeB magnets degrade faster in heat and humidity. The name comes from the Greek for "green twin." Its salts are pale green, even though the oxide is black.

Praseodymium trades at $245.40 per kilogram today, up 70% this year. It tracks neodymium step for step because the two are sold together. The Neo-Carester deal signed last week will run NdPr separation at Lacq, France — one of the few places outside China that can do it.

AROUND THE MARKET

Eight Rare Earth Conferences in September

September is the busiest month on the rare earth calendar. Rare-earth-mining.com counts eight conferences across Asia, Europe, and North America this month. Two years ago, you could count the year's dedicated rare earth events outside China on one hand.

China's Rare Earth Price Index Holds at 262.8

The Association of China Rare Earth Industry set its September 2 index at 262.8, with NdPr oxide at $107–111 per kilogram inside China and dysprosium at $214–221. Outside China, heavy rare earths trade at steep premiums — when they trade at all. The two markets keep drifting further apart.

September Market Outlook: Risks Mount

The November 10 export control deadline, a stalled Chinese second-half mining quota, and heavy rare earth scarcity are converging at the same time. NdPr prices fell in early September for the first time since May but remain up sharply year-to-date. The next 62 days may be the riskiest window of 2026.

Forbes, Zacks Name Top Rare Earth Stocks for September

Forbes and Zacks both published September rare earth stock picks, highlighting MP Materials, Energy Fuels, and Lynas Rare Earths. Both cite ex-China supply chain progress and the November 10 deadline as key factors. VanEck's REMX ETF sits near the middle of its 52-week range despite strong year-to-date gains across the rare earth complex.
