Toyota Tsusho and Japan’s state-backed JOGMEC have created an investment framework to support the development of heavy rare earths in Namibia, extending Japan’s strategy of securing overseas mineral supplies into an established African mining jurisdiction. The partnership is focused on materials such as dysprosium and terbium, two heavy rare earth elements that are important in the production of permanent magnets designed to maintain performance at high temperatures. These magnets are used across a range of strategic industries, including electric vehicles, offshore wind turbines, industrial motors, robotics and defence equipment.
Japan Expands Direct Mineral Investment
Japanese companies have traditionally combined minority investments, government-backed financing and long-term purchasing arrangements when securing overseas supplies of critical minerals. Such structures can spread project risk between private companies and the state while giving Japanese manufacturers greater visibility over future production.
The Namibian initiative follows that broader approach by linking commercial participation with government support rather than relying solely on conventional project finance. For Japan, securing heavy rare earths is particularly important because these materials form part of supply chains where processing and magnet manufacturing remain highly concentrated in China.
Namibia Could Support Wider Supply Diversification
The project also has potential relevance for European manufacturers, which face similar exposure to Chinese rare-earth separation and permanent-magnet production.
A commercially viable source of heavy rare earths in Africa could eventually provide material to both Japanese and European industrial markets, provided sufficient processing and separation capacity is developed outside China. Establishing a mine would represent only the first stage of building an alternative supply chain.
Heavy Rare Earths Require Complex Processing
Heavy rare-earth projects face significant technical requirements beyond conventional mining. Production can involve complex metallurgy and specialised separation circuits, while rare-earth deposits may also contain radioactive elements that require careful handling and waste management.
Before the Namibian project can become a dependable industrial supplier, it will need to demonstrate competitive recovery rates, product purity, appropriate waste-management systems and viable operating costs. The availability of downstream processing will also determine how effectively mined material can be converted into products suitable for manufacturers.
Namibia Seeks Greater Mineral Processing
Namibia provides an established mining regulatory framework, access to Atlantic Ocean ports and an expanding portfolio of mineral developments. The country is already associated with production and development involving uranium, lithium, tin and rare earths.
Namibia has also been seeking to expand domestic processing so that the country can capture more value from its mineral resources rather than relying primarily on exports of untreated concentrates. For heavy rare earths, the availability of processing infrastructure will be particularly important because extraction alone does not provide manufacturers with the separated elements required for advanced industrial applications.
Toyota Tsusho Provides Corporate Link
Toyota Tsusho is listed on the Tokyo Stock Exchange under ticker 8015. Its public-market exposure covers the wider trading and industrial group rather than representing a separately listed company dedicated solely to the Namibian rare-earth project. JOGMEC, meanwhile, is owned by the Japanese government and is not publicly listed. The structure illustrates how Japanese companies can combine corporate capital with government participation when entering strategically important overseas mineral projects.
Different Approaches to Critical Mineral Security
The Namibian initiative also highlights differences between Japanese and European approaches to securing critical raw materials. Japan has continued to use direct corporate investment, state-backed financing and long-term supply arrangements to establish access to strategic minerals.
European support has more often focused on mechanisms such as grants, regulatory designation and prospective purchasing frameworks.
As Namibia develops its heavy rare-earth resources, Japanese-backed investment could therefore provide an early route into industrial markets, even though European manufacturers could also become potential end users. The development underscores the broader competition to establish diversified supply chains for dysprosium, terbium and other critical rare earths, with mining, processing and long-term purchasing arrangements all required to reduce dependence on concentrated global production.
