Rapidus Semiconductor Project Gains New ¥150bn Government Investment

Rapidus

Rapidus semiconductor project funding has increased again as Japan commits another ¥150bn to support domestic advanced chip manufacturing. The new investment will help finance equipment for 2-nanometre semiconductor mass production and research into next-generation 1.4nm technology.

Rapidus semiconductor project support now includes ¥250bn in direct government investment following an earlier ¥100bn injection in fiscal year 2025-26. Japan is also planning substantial additional subsidies over the next two fiscal years.

Rapidus semiconductor project development is strategically important because Japan is trying to rebuild advanced logic chip manufacturing capacity after decades of declining domestic semiconductor production. The company aims to start mass production of 2nm chips in fiscal year 2027-28, followed by advanced packaging production in fiscal year 2028-29.

Japan Builds Domestic Leading-Edge Chip Capacity

The latest ¥150bn investment will support production equipment needed to move Rapidus from development toward commercial-scale semiconductor manufacturing. The company is targeting 2nm technology, placing the project in one of the most advanced segments of global chip production.

Rapidus is also conducting research into 1.4nm technology to prepare for the next generation of semiconductor manufacturing. Advanced chips are becoming increasingly important for artificial intelligence, data centres, automotive electronics, defence systems and high-performance computing.

This gives Rapidus strategic significance beyond the semiconductor industry itself. Domestic leading-edge chip capacity can reduce Japan’s exposure to concentrated overseas manufacturing and improve supply resilience for major industrial sectors.

Advanced packaging will also be important. As transistor scaling becomes more difficult, chip performance increasingly depends on how processors, memory and other semiconductor components are integrated.

Rapidus therefore needs to build capabilities across wafer fabrication, packaging and process technology rather than simply operate a conventional semiconductor plant.

Public Funding Must Unlock Large Private Investment

Government backing is substantial but will not finance the entire Rapidus programme. Japan plans to provide another ¥631.5bn in subsidies during fiscal year 2026-27 and around ¥300bn in fiscal year 2027-28.

Rapidus is also seeking roughly ¥1tn in private equity and more than ¥2tn in additional private financing. That funding requirement highlights the extraordinary capital intensity of advanced semiconductor manufacturing.

Leading-edge fabs require billions of dollars for lithography, deposition, etching, inspection and other highly specialised equipment. The investment also creates demand across advanced materials supply chains.

Semiconductor production relies on high-purity silicon, specialty gases, photoresists, copper, tungsten, cobalt, tantalum and other critical materials. Japan designated semiconductors as a critical material in 2022 and has since expanded support for domestic production.

Rapidus has become a central project in that strategy. The key challenge now is execution, including equipment installation, acceptable production yields, customer qualification and private-sector funding.

The Metalnomist Commentary

Rapidus shows that semiconductor security is becoming a capital-intensive industrial policy race. Japan’s challenge is not only funding a 2nm fab, but building the materials, equipment, packaging and customer ecosystem needed to sustain leading-edge production.
