1. The Same Year, Two Numbers
Thursday afternoon, February 22, 2024. Tokyo Stock Exchange.
The Nikkei 225 closed at 39,098.68. That surpassed the 38,915.87 recorded on December 29, 1989 — the peak of the bubble economy — for the first time in 34 years and two months. The session's biggest gainers were semiconductor equipment firms. Screen Holdings up 10.2 percent. Advantest up 7.5 percent. Tokyo Electron up 6 percent. The trigger was NVIDIA's earnings surprise, and the shock crossed the Pacific and landed in Tokyo.
But the same year produced a different number.
In April 2025, Japan's National Police Agency published its first official count. In 2024, 76,020 people died alone in their homes. Of those, 58,044 — 76.4 percent — were 65 or older. The Cabinet Office estimated that 21,856 died in isolation, undiscovered for eight or more days after death. Average time to discovery: 13.8 days. Meaning no one knew.
A Nikkei all-time high and 76,020 solitary deaths. Two numbers from the same country in the same year. While corporations were reviving, society was coming apart.
2. The Real Reason for the Lost 30 Years
The conventional narrative goes like this. The bubble burst in 1990, deflation followed, and structural reform failed. That narrative is not wrong. It is incomplete.
A more precise diagnosis locates the failure in technology transition. In 1988, Japanese semiconductor firms held 51 percent of the global market. Six of the world's ten largest semiconductor companies were Japanese. By 2019 that dominance had collapsed to below 10 percent. Thirty years of erosion.
The fall of Sony, Panasonic, and Sharp was not a single event. The three companies recorded combined losses of $20 billion in one fiscal year. While they were obsessed with hardware specification races, the age arrived in which software defined the ecosystem. Sony's e-reader, the Librie, supported only Japanese — and when Amazon's Kindle appeared, it was erased from history. The internet, mobile, cloud, AI — at every transition, Japan was a spectator.
The structural causes ran deeper. Lifetime employment delivers stability but suppresses radical innovation. Consensus-based decision-making — the ringi system (稟議制) — blocks speed. The success rate for digital transformation at Japanese firms is roughly 30 percent, against 80 percent in the United States and Germany. Venture-capital investment as a share of GDP stands at 0.08 percent — one-tenth the U.S. figure of 0.64 percent.
In Chapter 7 we saw ASML build an irreplaceable moat through thirty years of investment. Japan spent the same thirty years filling in the moat it already held.
3. The Semiconductor Revival — A National Bet
August 26, 2025. Stanford University, Hot Chips Conference.
A 73-year-old man walked to the keynote stage. Atsuyoshi Koike, CEO of Rapidus. It was his birthday. It was also the first time a Japanese person had taken that stage in 26 years — since 1999. Hot Chips is the frontier of semiconductor design: the venue where engineers from Intel, AMD, and NVIDIA present the latest chip architectures. The CEO of a company with no mass-production record took that stage on his birthday. He had served as president of Western Digital Japan and could have retired. He chose instead to become the person responsible for a national gamble.
Rapidus, founded in 2022, is Japan's first national semiconductor project in 30 years. The goal: mass production of 2-nanometer semiconductors by 2027. Understanding how provocative that declaration is requires context. Since Japan lost its semiconductor dominance, leading-edge process technology had been the exclusive domain of TSMC and Samsung. Rapidus was entering that arena as a late arrival — in a field those two companies were already mass-producing.
A strategic partnership with IBM transferred 2nm GAA (gate-all-around) transistor technology. Collaboration with IMEC, Belgium's semiconductor R&D institute, is also underway. In April 2025, the first EUV exposure succeeded at the IIM-1 plant in Chitose, Hokkaido. On July 18, 2025, Rapidus announced successful electrical characterization of a 2nm GAA transistor prototype. More than 60 potential customers are in discussions.
Chitose was chosen for a reason. Water resources essential to semiconductor manufacturing, a cold climate, and access to renewable energy — all present. Since groundbreaking, 4,000 construction workers have poured in, and apartment blocks and restaurants have begun appearing on the farmland near the airport. The scene overlaps, in a peculiar way, with the heavy-chemical industrial cities Korea was building in the 1960s and 1970s.
Among those supervising the cleanroom design on that construction site, people in their sixties are not rare. Hiroshi Tanaka (a pseudonym), 64. He spent 30 years at NEC as a semiconductor process engineer before taking early retirement when his division was sold in 2012. For the next decade he drifted through quality-control positions at automotive-parts firms. He saw Rapidus's job posting in the spring of 2023. "I wanted to touch semiconductors one last time before I retired," he said. In Chapter 4 we saw TSMC's Kumamoto plant rise from farmland — in Chitose, the same scene is repeating itself, shaped by the hands of engineers who carry 30 years of absence. The distinction between Tanaka and the displaced figures we will examine in Chapter 14 is clear. Tanaka was pushed aside and then called back. The separate question is whether there is a sufficient next generation to inherit what his cohort knows, once they retire.
The Japanese government's commitment is expressed in numbers. Cumulative semiconductor subsidies since 2022: $25.7 billion — the largest in the world relative to GDP. The total investment required for Rapidus is estimated at roughly ¥4 trillion (approximately $27 billion); approximately ¥1.7 trillion has been secured to date. The Japanese government holds an 11.5 percent voting stake and a golden share carrying veto rights. The decision to enter was made by the state, not the market.
In Chapter 4 we saw Taiwan's TSMC function as the silicon shield. That same TSMC came to Japan as well. February 24, 2024. Kikuyo-machi, Kumamoto Prefecture. TSMC founder Morris Chang, chairman Mark Liu, and CEO C.C. Wei took the stage at the opening ceremony of JASM (Japan Advanced Semiconductor Manufacturing). The joint venture draws minority stakes from Sony, Denso, and Toyota. It produces wafers at 12nm and 22nm processes, with a monthly capacity of 55,000 wafers. Sony's image sensors and Denso's automotive semiconductors are the plant's primary customers. A second plant (6–7nm) is scheduled for operation in 2027; combined investment for both plants exceeds $20 billion.
Land prices in Kumamoto Prefecture — where JASM is located — recorded the highest rate of increase in Japan. Commercial land in Kikuyo-machi rose 66 percent over three cumulative years. Starting salaries for university graduates significantly exceeded the Kumamoto average, at ¥280,000. More than 35 related companies have established a presence in the region. A single plant changed the gravitational center of the regional economy.
Both optimism and skepticism coexist. The critique that a 30-year gap has dissolved the engineer ecosystem, and that winning customers as a latecomer will not be easy, is valid. Yet Japan still holds a different card: semiconductor materials. Photoresist — 87 to 91 percent of the global market. Silicon wafers — 53 percent. Coater and developer equipment — 88 percent. These numbers are evidence that Japan controls the "invisible bottleneck" of semiconductor manufacturing.
4. The Country of the Old, Building a Future
As of 2024, Japan's population aged 65 and over stands at 36.25 million — 29.3 percent of the total population. The oldest country in the world. The total fertility rate hit a record low of 1.15 in 2024. Median age: 50.8. Total population is projected to fall to 104.9 million by 2050.
The 76,020 solitary deaths are the product of this structure. The care-worker shortage is projected to reach 570,000 by 2040. Approximately 9 million vacant homes — akiya (空き家) — are scattered across the country. Some research suggests that nearly half of all Japanese municipalities face the risk of disappearing by 2050.
Behind that number is a face. An apartment block in Adachi Ward, Tokyo. Kenta Yoshida (a pseudonym), 41. He has been a field supervisor at the specialized cleaning firm ReLife for seven years. Every time he opens a door in a hazmat suit, what he confronts is not death but absence — the fact that someone lived here and no one noticed. After body fluids have soaked into the floor, the wallpaper must be stripped, the flooring pulled up, and ozone treatment applied before the space is restored. It normally takes three hours to several days, at a cost of hundreds of thousands to millions of yen. Average time to discovery after death: 13.8 days — during which advertising flyers pile up in the mailbox, and neighbors noticed an odd smell but did not knock on the door. Yoshida handles an average of 12 cases a month. The longest-neglected scene he has worked was four months after death. He said the hardest days are when family photographs turn up among the personal effects — there are people in the photos, but in reality no one came. Specialized cleaning is a growth industry in Japan. That fact alone is a diagnosis.
Yet Japan's response to this crisis is distinctive. Not surrender, but experiment.
At a care facility in Setagaya Ward, Tokyo, 79-year-old Mr. Sakamoto held the seal-shaped robot PARO for the first time and could not put it down. PARO is 57 centimeters long, 2.7 kilograms. It tilts its head and blinks in response to touch, sound, and light. Five thousand units have been deployed worldwide; 3,000 are in Japan. The Shintomi care facility in Tokyo introduced 20 types of robots including PARO and became an official model facility for the Japanese government. Multiple studies have found that care robots meaningfully reduce stress and feelings of isolation among elderly residents.
Japan is conducting "the world's first large-scale experiment in using AI and robots to compensate for population decline." Second-largest market for industrial robots in the world. Service-robot market size in 2025: $1.44 billion. Care-robot subsidies in the 2025 budget: approximately ¥30 billion. AI medical imaging diagnosis, remote consultation, autonomous elderly-transport services — all of it driven by the pressure of demographic aging.
The paradox of reconstruction lies here. Japan pioneering the aging-solutions market was not a choice. It was unavoidable. Because it was the first to face the crisis, it became the first to search for answers.
5. Stock Market at Its Peak, Population at Its Trough
In Chapter 9 we saw the UAE try to buy the future with capital. Japan is different — it already paid with thirty years of time.
Does the Nikkei record high mean Japan's revival? Look at the numbers. Seventy percent of that rally was driven by foreign investors. Japanese domestic individual investors stayed on the sidelines. Warren Buffett drew attention when he increased his stakes in Japan's five major trading companies to an average of 8.5 to 9.8 percent, and his own explanation is telling: "I simply looked at the financial records and was astonished at how low the stock prices were." Not evidence of revival — proof of how deeply undervalued Japan had been for thirty years.
In 1989, 32 of the world's top 50 companies by market capitalization were Japanese. In 2024, of the top 50, just one Japanese company made the list: Toyota.
Yet reading this as complete defeat is also difficult. The Bank of Japan ended its negative-interest-rate policy in March 2024. Wage growth reached its highest level since the 1990s. Inflation exceeded the 2 percent target for more than two years running. Signals of escape from deflation — the structural hallmark of the "lost 30 years" — are emerging. In 2024, the Japanese government pushed corporate governance reform to strengthen board independence and open the door to activist investors.
Corporate revival and social disintegration are proceeding simultaneously. On the day semiconductor equipment stocks surged, 76,020 people died alone. These two realities are not a contradiction. They are two outcomes of the same structural choice.
6. The Shadow of Fukushima, the Reality of Energy
December 2025. Kashiwazaki-Kariwa Nuclear Power Plant, Niigata Prefecture. The largest nuclear power station in the world. Maximum output: 8.2 million kilowatts. Behind newly built seawalls and flood barriers, TEPCO (Tokyo Electric Power Company) was preparing to restart Reactor No. 6 — TEPCO restarting a nuclear plant for the first time in 14 years, since the Fukushima Daiichi accident.
At the same moment, 300 protesters gathered at the plant's main gate. "No restart." Sixty percent of Niigata residents said the conditions for restart had not been met; 70 percent said they did not trust TEPCO's operational competence.
Yet the numbers speak from the other side as well. Sixty to 70 percent of Japan's electricity depends on imported fossil fuels. Annual LNG and coal import costs alone: ¥10.7 trillion, approximately $68 billion. The surge in AI data-center demand is pushing electricity consumption higher. The government's calculation is that the nuclear share must rise from the current 8 to 9 percent to 20 percent by 2040.
After Fukushima, Japan attempted a full nuclear halt followed by a pivot to renewables. When offshore wind projects ran into trouble, it turned back to nuclear. Fourteen reactors are currently operating; three more await additional approval. IHI and Chubu Electric have also entered small modular reactor (SMR) development. Caught between trauma and reality, Japan chose reality.
In Chapter 8 we saw Indonesia try to ride the resource curse upward. Japan is the opposite — a country with no resources, and the cost it must pay to secure energy. The choice to restart nuclear plants even while carrying the memory of Fukushima. That is not surrender. It is the survival strategy of a country with no alternatives.
7. Japan Between the United States and China — and the Weaponization of Materials
The geopolitical position Japan has chosen is a dual strategy: tilt toward the United States while maintaining the Chinese market. The Economic Security Promotion Act enacted in 2022; participation in U.S. semiconductor export controls; restrictions on advanced semiconductor equipment exports to China. At the same time, China remains Japan's largest trading partner. Japan's exports to China in 2024: $124.6 billion. Full decoupling is not realistically possible.
Japan's leverage sits deeper than is generally recognized. In July 2019, when Japan restricted exports to Korea of hydrogen fluoride, photoresist, and fluorine-coated polyimide — three semiconductor materials — the world witnessed that materials dominance can become technology dominance. Korea's hydrogen fluoride imports fell 87.9 percent. The Korean government was forced to announce in August 2019 a plan to invest ₩7.8 trillion over seven years in localizing materials, components, and equipment.
Photoresist, silicon wafers, coater and developer equipment. This is the "materials bottleneck" of semiconductors. If the United States holds the semiconductor equipment bottleneck through ASML, Japan holds the semiconductor materials bottleneck. When the two bottlenecks combine, no country can manufacture advanced semiconductors without the consent of both.
8. What the Mirror Shows
Applying the core formula, Japan is a case of the sequence running in reverse. In 1988, Japan stood at the peak of technological innovation. But the concentration of capital that followed produced social inertia — lifetime employment, consensus culture, resistance to change — and the country failed at institutional redesign. It missed the digital transition, missed the software platform, was late to AI. The formula ran backward. Technological advantage generated concentration of capital, but social inertia blocked institutional redesign, and thirty years passed.
Now Japan is attempting to run the formula forward again. State-led technology investment — Rapidus and the recruitment of JASM — is concentrating capital, and that pressure is driving institutional redesign in the form of corporate governance reform. Whether it will succeed remains unknown.
From the perspective of The Strategy of the In-Between, Japan stands between hardware and software, between its former manufacturing dominance and the future AI ecosystem, between the American alliance and the Chinese market. Failing for thirty years to set a direction within that between — that was the "lost 30 years." What Japan is searching for now is the method of turning that between into leverage again.
While Tanaka unfolds cleanroom blueprints in Chitose, Yoshida heads to his next site in Tokyo. The semiconductor revival and the 76,020 solitary deaths are two time zones inside the same country — one is time spent trying to reclaim the future, the other is time in which the present has already ended. The mirror shows the future. But the mirror does not change it. What changes things is the task of the one standing before it.
Korea in the Mirror
Japan stands ten to twenty years ahead on the road Korea is walking. The same crisis, at a different speed, has already played out.
The parallel is not perfect. Japan had buffers Korea lacks — the scale of a domestic market, the weight of the world's third-largest economy, and a manufacturing technology ecosystem accumulated since the 1960s. Korea has none of that. Which is precisely why the future the mirror reflects is sharper.
The fertility reversal. Japan's total fertility rate was 1.15 in 2024. Korea's was 0.72 (record low in 2023, recovering slightly to 0.75 in 2024). While Japan suffers from ultra-low fertility, Korea is running below it. That means Korea reaches the same crisis faster. The caregiver shortages, the proliferation of vacant homes, the disappearance of regional towns that Japan experienced over decades — Korea will face all of it within a more compressed window. In September 2025, Korea officially entered "super-aged society" status, with the population aged 65 and over exceeding 20 percent.
The lesson from semiconductors. It took Japan thirty years to fall from 51 percent of the global market in 1988 to below 10 percent in 2019. And it required another thirty years to re-enter the 2nm race. That is what Rapidus means: losing semiconductors costs thirty years to recover. This is why Korea must defend the competitiveness of Samsung Electronics and SK hynix right now. Defense is far cheaper than recovery.
Solitary deaths and single-person households. Japan's 76,020 solitary deaths are a picture of what Korea, ten to fifteen years later, has already begun. Korea's share of single-person households exceeded 35 percent of all households in 2024. Elderly single-person households, young single-person households — as those numbers accumulate, the same structural isolation Japan has will form. Care robots like PARO, IoT wellness-check systems, community care models — the solutions Japan is validating will become Korea's practical agenda five to ten years from now.
Immigration and the speed of institutions. It took Japan thirty years to dismantle its exploitative technical-intern trainee program and transition to the new "육성취로" (Ikusei Shuro) system in 2024. Korea is attempting institutional reform by introducing the K-STAR visa and Top-Tier visa in 2025–2026. Korea is moving faster than Japan — but compared with Singapore's 30 percent foreign-resident population, Korea's 5.3 percent is still a distant figure. The window for compensating population decline with immigration is not long.
The oscillation of energy policy. Japan oscillated after Fukushima — from a full halt, to a restart, from offshore wind, back to nuclear — but ultimately set a direction. Korea swings more dramatically. From Moon Jae-in's nuclear phase-out to Yoon Suk-yeol's nuclear expansion, energy policy reverses with every change of administration. Unlike Japan, which after fourteen years of debate reached the consensus of "choosing reality even while carrying the trauma," Korea has not yet reached the starting line of consensus. The surge in power demand in the AI era makes this decision impossible to defer any further.
Materials and the possibility of cooperation. Japan's materials export restrictions in 2019 rattled Korea. But the materials-components-equipment localization drive that followed paradoxically became the occasion to reinforce Korea's structural vulnerabilities. Today, the combination of Japanese photoresist and Korean semiconductor manufacturing could become the core of Northeast Asian semiconductor cooperation within the context of US-China competition. Just as Israel chose the American side on the Haifa port question in the interest of security, Japan-Korea semiconductor cooperation is not a choice — it is structural logic.
Seven mirrors have been examined. Taiwan's silicon shield, Israel's military-technology cycle, Singapore's hub strategy, Hong Kong's failed choice, the Netherlands' monopoly leverage, Indonesia's resource ladder, the UAE's sovereign capital. And now Japan — a country that walked thirty years ahead, showing the map of crisis and partial revival.
Now the mirrors are set down. It is time to look at Korea itself.
→ Into Part III: In Chapter 11, Korea steps before the mirror — this time as the strategist.
