Greenland's Critical Minerals
Japan Sends Delegation to Greenland to Assess Rare Earth Mining Feasibility
Key Points
Greenland is an autonomous territory within the Danish kingdom, a detail shaping how Japan would need to coordinate with Greenlandic authorities and governance structures rather than treating it as a fully sovereign state.
Japan’s push is tied not only to clean-energy hardware but also to everyday consumer and electronics supply chains: rare earths are used in “smartphones, computers… batteries,” alongside electric vehicles and wind turbines—expanding the breadth of sectors Japan is trying to protect.
A Nikkei explainer notes that rare earth elements are “not actually ‘rare’ in terms of their geological abundance,” but are hard to extract economically and require “complex processing techniques,” underscoring why feasibility work (not just deposit mapping) is essential.
The articles emphasize that Greenland mining would require “significant investment and careful planning,” indicating the project would likely involve more than geological screening—potentially affecting timelines and commercial viability.
Japan is sending an official delegation to Greenland this summer to assess rare earth mining sites, Reuters reported. The group will include officials from the Ministry of Economy, Trade and Industry, major trading firms, and JOGMEC, the country's metals and energy security agency.
The push comes as China's rare earth exports to Japan have plummeted 80% year-on-year, according to Nikkei Asia, creating an immediate supply crunch for Japanese automakers and electronics makers. Rare earths are used in electric vehicles, wind turbines, smartphones, and computers — making them critical to Japan's entire industrial base.
Why Greenland Has Japan's Attention Right Now
Greenland sits atop vast rare earth deposits that remain largely untapped. One project, Tanbreez, holds an estimated 28.2 million tonnes of rare earth resources — potentially the largest in the world, according to Mining.com. Another site, Kvanefjeld, holds over 11 million tonnes, including 370,000 tonnes of the heavy rare earths Japan needs most.
Japan also has its eye on a broader trend. The Trump administration has aggressively pursued influence over Greenland, framing it as essential to Western security. That shift — from Trump's 2019 purchase talk to active diplomatic and commercial engagement — has accelerated the race among allied nations to lock in access, Travel and Tour World noted.
China Supply Shock Forces Japan to Look North
China controls roughly 60% of global rare earth production and an even larger share of processing. Japan learned this lesson in 2010, when Beijing briefly cut off exports during a territorial dispute. In 2026, that scenario has repeated at far greater scale. The 80% drop in Chinese exports — tied to tensions over Taiwan — has left Japanese factories scrambling, according to Discovery Alert.
Japan's response goes beyond the Greenland trip. Shin-Etsu Chemical is investing 35 billion yen — about $218 million — into a new refinery in Fukui specifically designed to process ore from Arctic and Southeast Asian sources, Mining.com reported. The goal is to build a supply chain that does not run through Beijing.
Big Obstacles Stand Between Greenland and Japan's Supply Chain
Mining in the Arctic is not simple. Greenland lacks the ports and power grids needed for large-scale extraction. Only Nuuk has a year-round port. Experts at Global Mining Review say meaningful output is likely a decade away. The extreme cold and remote terrain would require building infrastructure almost from scratch.
There is also a political and environmental tangle. Greenland is an autonomous territory within the Danish kingdom — Japan must negotiate with both Copenhagen and Nuuk. Greenland's local government bans uranium mining, which is a problem because some rare earth deposits sit alongside radioactive materials. Inuit communities near the Narsaq region have raised concerns about toxic tailings and radioactive waste, according to Guru Focus.
The Delegation's Visit Is a First Step, Not a Fix
The summer mission is primarily a feasibility study — not a mining deal. As Nikkei has explained, rare earth elements are not actually geologically rare, but they require complex processing to extract economically. That is why Japan needs boots on the ground, not just maps. The delegation will assess whether extraction is technically and commercially viable under real Arctic conditions.
For Japan, the stakes are high. A stable rare earth supply underpins its entire clean energy and electronics economy. But Citigroup analysts note that the high cost of Arctic mining is now a "necessary premium" given the China supply crisis, according to Mining.com. The Greenland trip signals that Japan is willing to pay that price — even if the payoff is years away.
