Japan has unveiled an ambitious new industrial target aimed at dramatically expanding the country’s semiconductor sector, with the government setting a goal of reaching 40 trillion yen in domestic chip sales by 2040.
The initiative forms a central pillar of Prime Minister Sanae Takaichi’s broader economic growth strategy, which prioritises strategic technologies seen as critical for national security and long-term competitiveness.
Officials say the plan reflects Japan’s determination to regain relevance in the global semiconductor market while positioning domestic manufacturers to benefit from surging demand driven by artificial intelligence and advanced computing technologies.
Expanding Investment In Strategic Industries
Under the government’s roadmap, semiconductors will receive expanded public investment alongside other technologies deemed vital to economic security, with detailed policy measures expected to be finalised in the coming months.
Those plans will later be incorporated into the government’s annual budget process, ensuring that semiconductor development remains a long-term priority within Japan’s broader industrial and technological policy framework.
The 2040 objective significantly expands on an earlier government target that aimed to reach 15 trillion yen in annual chip sales by 2030, highlighting the administration’s belief that global demand will accelerate rapidly.
At present, Japanese semiconductor manufacturers generate roughly 8 trillion yen in annual sales, meaning the newly announced goal would require a fivefold expansion of the industry over the next fifteen years.
Japan’s Historical Rise And Decline In Chips
Japan once dominated the global semiconductor market during the 1980s, when the country controlled roughly half of worldwide chip production and played a central role in electronics manufacturing supply chains.
However, that dominance faded in the following decade as trade tensions with the United States intensified while Japan’s once-powerful domestic electronics sector began losing competitiveness to emerging Asian manufacturing hubs.
The combined effect of international pressure and industry contraction gradually eroded Japan’s influence in the semiconductor sector, leaving the country with less than ten percent of global market share today.
Despite that decline, Japanese companies remain important suppliers of specialised chipmaking materials, equipment, and components that continue to underpin global semiconductor manufacturing processes.
Artificial Intelligence Driving Industry Expansion
Government officials say the explosive growth of artificial intelligence technologies has created a new window of opportunity for Japan to rebuild its semiconductor capabilities and attract investment into advanced chip production.
Artificial intelligence applications require increasingly powerful processors and sophisticated chip architectures, creating rising demand for both advanced semiconductor design and large-scale fabrication capacity around the world.
By strengthening domestic manufacturing and research capabilities, policymakers hope Japan can capture a greater share of that expansion while reducing reliance on foreign chip suppliers.
The strategy also reflects growing global concern over supply chain resilience, as governments increasingly view semiconductor production capacity as a matter of national security and technological sovereignty.
If successful, the policy could help Japan rebuild a stronger presence in one of the world’s most strategically important industries while ensuring the country participates fully in the next wave of technological innovation.
