Noah Smith identifies a counterintuitive lever for Japan's economic revival: rather than forcing foreign takeovers of domestic firms, the nation should aggressively court foreign companies to build new factories and research centers from the ground up. This piece cuts through the noise of generic "open for business" rhetoric by distinguishing between mere ownership changes and the tangible capital injection of greenfield investment, offering a specific blueprint for how Japan can re-enter the global semiconductor and AI races.
The Semiconductor Pivot
Smith anchors his argument in the most critical industrial battleground of our time: the semiconductor industry. He notes that while the U.S. and Japan once dominated chip design and tooling, they lost the crucial fabrication stage to a single entity. "TSMC are essentially the world's greatest machinists," Smith writes, highlighting how the Taiwanese giant's "pure-play foundry" model allowed it to outcompete every other nation. This historical context is vital; it explains why Japan cannot simply rely on its own legacy firms to catch up. The administration's strategy has shifted from pure indigenization to a hybrid model, exemplified by the rapid construction of TSMC's first plant in Kumamoto, which opened in February 2024.
Smith points out that this success wasn't accidental. The project involved significant government subsidies and logistical support, creating a "renaissance of semiconductors" that even TSMC's founder, Morris Chang, once doubted was possible in Japan. "TSMC credited the successful construction to a variety of local supporting institutions," he notes, contrasting this speed with delays seen in American projects. This suggests that the executive branch's ability to coordinate infrastructure, water, and labor is a competitive advantage that can be replicated.
"Japan is building chips for TSMC... These investments by foreign companies aren't Japan's only strategy for reviving its semiconductor industry — they coexist alongside homegrown efforts... But they represent a crucial addition to the purely indigenous efforts."
Critics might argue that relying on a single foreign supplier for critical defense infrastructure creates a new form of dependency. However, Smith frames this as a necessary step in a multi-strategy approach, where foreign fabs coexist with domestic ventures like Rapidus. The key takeaway is that Japan is no longer trying to do everything alone; it is leveraging global capital to fill its specific gaps.
The AI Renaissance and the Power of Failure
The commentary then pivots to software, an area where Japan has historically lagged behind the U.S. and China. Smith uses the rise of Sakana AI to illustrate how foreign talent and capital can jumpstart a domestic ecosystem. He details the company's unique approach of using groups of smaller models rather than one massive statistical engine, a strategy that could address the skyrocketing energy demands of modern AI. "Sakana's presence has put Japan on the map as a potential hotspot for international AI investment," Smith observes, citing the involvement of Nvidia and American venture capital firms.
Perhaps the most compelling part of Smith's analysis is his reframing of failure. In a high-stakes industry, the fear of loss often paralyzes investment. Smith argues that even unsuccessful ventures contribute to the ecosystem. "The investment and attention that Sakana draws to the Japanese AI startup scene will help make sure that some of those successes happen in Japan," he writes. He draws a parallel to historical precedents, noting that while Fairchild Semiconductor wasn't ultimately successful, its alumni went on to found Intel. Similarly, General Magic's failure in the 1990s paved the way for the iPhone. This perspective is crucial for a culture that often stigmatizes business failure.
"Even failed startups often contribute crucial innovation to a country's ecosystem... Sakana sends a signal that Japan is a viable destination for international investment in the software industry in general, well beyond AI."
Smith acknowledges the risk that the entire AI sector could face a bubble burst similar to the dot-com crash of 2000. Yet, he insists that the long-term importance of the technology outweighs the short-term volatility. The argument here is that the process of building these companies is as valuable as the companies themselves, creating a network of talent and knowledge that persists even if specific startups fold.
The Greenfield Advantage
The core of Smith's thesis rests on a technical distinction that most policymakers overlook: the difference between mergers and acquisitions (M&A) and greenfield investment. While many advocates push for foreign buyouts to improve management efficiency, Smith argues this approach carries significant social risks, such as job cuts and asset stripping. Instead, he champions "greenfield platform FDI," where foreign entities build new facilities specifically to export goods or services.
Smith explains that this model directly stimulates the local economy. "When a foreign company builds a factory in Japan, or even just purchases office equipment for a new office, that represents real money that goes directly into Japanese people's pockets," he writes. Unlike M&A, which simply changes ownership, greenfield investment creates new jobs and generates immediate economic activity. He cites research by Ito, Tanaka, and Jinji (2023) showing that the Japanese public is far more receptive to new construction than to foreign takeovers, which are often viewed with suspicion as "vulture fund" activities.
"Greenfield platform FDI has a very good economic track record. It has been key to the economic success of a number of developing countries — most notably China, but also Poland and Malaysia."
Smith draws a powerful historical parallel to China's post-2001 boom, where foreign factories were built not just to sell to Chinese consumers, but to exploit lower costs for export to the rest of the world. This "platform" strategy allowed China to become the world's factory floor. He suggests Japan can replicate this by leveraging its high-quality labor and infrastructure to become a hub for exporting high-tech goods, rather than just a market for foreign products. The argument is that by focusing on exports, Japan can reverse its trade deficit and revitalize its manufacturing base without sacrificing its social safety net.
"Greenfield FDI inevitably results in the hiring of more Japanese workers, since someone has to work at the new factory or office branch. Investment spending and workers' salaries in turn stimulate the surrounding local economy."
Bottom Line
Noah Smith's argument is strongest in its precision: by isolating greenfield investment from the broader, more controversial topic of foreign ownership, he offers a politically viable path for Japan's economic renewal. The piece effectively demonstrates that the Kumamoto semiconductor boom is not an anomaly but a replicable model for the AI and software sectors. The biggest vulnerability remains the execution—Japan must maintain the bureaucratic agility that allowed TSMC's rapid construction while resisting the urge to retreat into protectionism. The world is watching to see if this "platform" strategy can truly transform Japan from a developing economy back into a global leader.
