- For much of the post-Soviet period, Central Asia occupied a peripheral position in global economic and political analysis, overshadowed by Russia and China. More recently, its concentration of critical minerals and its geographic role linking Europe and Asia have pushed the region up the strategic agenda amid efforts to diversify trade routes and reduce geopolitical risk.
- Tokyo’s renewed engagement, culminating in the first Central Asia-Japan Leaders’ Summit in December, reflects a shift away from its symbolic diplomacy toward a more economically grounded approach.
Japan’s relationship with Central Asia
- Japan’s engagement with Central Asia dates back to the 1997 launch of Eurasian Diplomacy, which framed Tokyo as a developmental rather than geopolitical actor. Through ODA-financed transport, energy and water projects, alongside governance support and cultural exchange, Japan cultivated a reputation as a non-imperialist “distant friend.” This low-profile “silk diplomacy” generated goodwill across the region, but it lacked a clear commercial and strategic anchor.
- Concerns over provoking Russia and China, combined with Central Asia’s status as a secondary priority amid domestic economic pressures, resulted in fragmented engagement and limited economic returns.
What’s changed?
- That approach shifted decisively in December 2025. Japan pledged ¥3 trillion (approximately $20bn) in investment for business and infrastructure projects, with Japanese firms expected to play a central role in delivery. Cooperation is now organised around three pillars (Green Resilience, Connectivity and Human Resource Development) signalling a move away from broad policy dialogue toward targeted, project-level engagement and private-sector participation (MOFA, 2025).
What does Japan have to gain?
- The economic logic is increasingly clear. Central Asia holds a dense concentration of critical minerals, accounting for around 30% of global chromium reserves, while Kazakhstan alone can supply more than 20 of the EU’s 34 critical raw materials (Hague Research 2023). For a resource-poor, import-dependent economy, deeper engagement supports Japan’s supply security while opening commercial opportunities in infrastructure, processing and services.
- Geopolitics reinforces this shift. Sanctions on Russia have weakened Central Asia’s participation in global value chains and undermined the reliability of Russia-centric trade routes. This has created a shared interest in alternative connectivity, particularly via the Trans-Caspian International Transport Route, which bypasses Russia entirely and improves access to global markets.
Cordoba’s view
- Japan’s re-engagement represents a structural upgrade rather than a symbolic reset. While it will not displace Russia or China, Tokyo is emerging as a credible third actor, leveraging long-standing goodwill to align its investment and connectivity agenda with Central Asia’s growing demand for diversification and economic autonomy. As identified by the leaders’ summit, some of the most important sectors to watch going forward include green energy infrastructure and regional trade connectivity, particularly projects linked with the TITR.
