Introduction
The semiconductor industry is at a turning point, with the emergence of next-generation technologies like 2nm chips. Japan’s Rapidus, a relatively new player in the field, has ambitious plans to lead in this arena. However, achieving this milestone comes with significant hurdles. Chairman Tetsuro Higashi recently outlined the five major challenges Rapidus faces in its pursuit of mass production for 2nm chip production.
These challenges span technical, market, and financial domains, and their resolution is critical for both the company and Japan’s semiconductor ambitions.

Overview of Key Challenges
- Technical Feasibility of Mass Production: Jumping directly to 2nm is daunting given Japan’s limited recent experience in advanced chip manufacturing.
- Market and Customer Positioning: Competing with giants like TSMC requires a unique value proposition.
- Funding Issues: Heavy reliance on government subsidies raises questions about sustainability.
- Energy-Efficient Chip Design: Meeting the demands of emerging markets like AI and robotics necessitates cutting-edge innovation.
- Private Investment Gap: Securing significant private sector funding is essential for long-term growth.

Technical Feasibility of Mass Production
Japan’s semiconductor manufacturing capabilities have historically lagged behind leading global players, with recent success limited to 40nm production processes. Rapidus decision to leap directly to 2nm chip production technology has drawn skepticism. Critics argue that such an aggressive approach could be reckless.
Despite this, Higashi remains optimistic. Partnerships with IBM and leading semiconductor equipment manufacturers provide access to advanced technologies and expertise. IBM’s earlier work in 2nm chip development offers Rapidus a foundation to build upon. Additionally, Japan’s long-standing reputation for precision engineering could play a crucial role in overcoming these hurdles.
Higashi also ruled out entering mid-tier markets, citing saturated competition. Instead, Rapidus aims to compete in the high-end segment, where innovation and differentiation could level the playing field.

Market and Customer Positioning
Rapidus seeks to differentiate itself by targeting specialized semiconductor markets rather than competing with industry behemoths like TSMC in standardized chip production. Higashi envisions a shift away from general-purpose chips toward application-specific solutions.
At Semicon Japan 2024, Higashi highlighted the inefficiencies of standardized chips, emphasizing their excessive energy consumption. Rapidus plans to innovate energy-efficient semiconductors tailored for emerging applications like robotics, autonomous vehicles, and telemedicine.
The generative AI market offers particularly promising opportunities. Higashi predicts a transition toward dedicated chips optimized for specific AI algorithms, a market niche Rapidus hopes to dominate. This approach aligns with the global push for sustainable and efficient semiconductor solutions.
Funding Challenges
Financing remains one of Rapidus’s most pressing concerns. The company estimates a staggering JPY5 trillion (approximately USD 32 billion) is needed to achieve mass production. At present, the majority of this funding comes from Japanese government subsidies, which totaled JPY920 billion over three fiscal years.
Prime Minister Fumio Kishida has prioritized semiconductor and AI industries, pledging over JPY10 trillion in support by 2030. However, critics warn that prolonged reliance on government funding could turn Rapidus into a de facto state-owned enterprise. Such a model risks inefficiency and limited effectiveness, as seen in other state-led initiatives.
Higashi acknowledges these concerns and stresses the importance of transitioning to private sector funding. The company aims to finance factory construction through bank loans and private investments, targeting 50% of equipment costs from non-government sources.
Energy-Efficient Chip Innovation
In a world increasingly focused on sustainability, Rapidus positions itself as a pioneer of energy-efficient semiconductors. Higashi envisions chips that consume one-fifth the energy of current technologies. This focus is crucial for markets like AI, where energy demands are skyrocketing.
Future products aim to cater to high-demand areas such as robotics and telemedicine. These fields require specialized chips capable of handling unique workloads with minimal energy waste, giving Rapidus a competitive edge in emerging markets.
Securing Private Investment
Private investment remains a critical gap in Rapidus’s strategy. Investors are wary due to the inherent risks of entering advanced semiconductor manufacturing, especially given Japan’s limited recent track record in the field.
To attract private capital, Rapidus needs to demonstrate technical feasibility and market demand. Collaboration with established players like IBM and the Japanese government’s support may serve as confidence boosters. Long-term sustainability hinges on the company’s ability to balance public and private funding effectively.
Japan’s Semiconductor Ambitions
Rapidus’s journey reflects broader efforts by Japan to reclaim its position as a semiconductor powerhouse. Once a global leader, Japan lost ground to Taiwan, South Korea, and the U.S. over the past two decades. The government’s aggressive investments in Rapidus signal a commitment to revitalizing the sector.
Semiconductors are critical for industries ranging from automotive to AI. As nations scramble to secure their supply chains, Rapidus’s success could redefine Japan’s role in the global semiconductor ecosystem.

Conclusion
Rapidus faces an uphill battle as it pursues 2nm chip production. Technical hurdles, market differentiation, funding challenges, and the need for private investment are daunting but not insurmountable. By leveraging strategic partnerships and focusing on specialized, energy-efficient solutions, Rapidus has the potential to carve out a niche in the competitive semiconductor industry.
The stakes are high—not just for Rapidus but for Japan’s ambition to regain its leadership in technology and innovation. Only time will tell if Rapidus can overcome these challenges and deliver on its promise of next-generation semiconductor excellence.
