The Phoenix Project: Japan’s Semiconductor Revival and Korea’s Response
Direct subsidies, international cooperation, and materials/equipment moats from the KOTRA report
0. Bottom line first
The conclusion is blunt: semiconductor investment should not rely only on tax deductions after the fact. Korea needs to take Japan-style direct fiscal support at the investment-decision point much more seriously.
Official fact: The source attaches a KOTRA report PDF and a Gemini audio file and frames Japan’s semiconductor revival as a “100 trillion won ambition.” It notes that Japan had six of the world’s top ten semiconductor companies in 1990, but its global market share fell below 10% by 2019.
Interpretation: Japan’s current strategy is not a replay of past success. It is a reversal of past failure: instead of closed domestic self-reliance, Japan is pulling in external leaders such as TSMC, IBM, and imec while using Rapidus to attempt a return to leading-edge manufacturing.
1. Japan’s grand strategy: designed from failure
Japan’s current policy is not simply reviving the old formula. After Intel’s DRAM development in the 1970s, Japan accumulated technology through Panasonic, Hitachi, NEC, Toshiba, and others. In the 1980s, the VLSI Technology Research Association reduced duplicate R&D and supported materials, parts, and equipment suppliers.
The decline came from external pressure through the U.S.-Japan Semiconductor Agreement and Plaza Accord, internal strategic failure from remaining too comfortable with vertically integrated IDM models and internal transactions, and weaker investment/R&D after the bubble collapse. Elpida’s bankruptcy in 2012 and Toshiba’s semiconductor sale in 2017 are presented as symbols of that decline.
Closed structure
IDM-centered internal markets missed the global fabless-foundry separation.
External capability
Japan is attracting leaders such as TSMC and cooperating with IBM and imec.
Direct subsidies
Cash-like support at the investment-decision stage creates speed.
2. Japan’s moat: materials and equipment
Japan’s revival strategy is not built in the air. The source states that Japan holds 48% of the global semiconductor materials market and 31% of the equipment market, ranking second after the United States. That means Japan remains a hidden controller of key supply-chain bottlenecks.
| Category | Item | Major companies/countries | Strategic meaning |
|---|---|---|---|
| Materials | Silicon wafers | Shin-Etsu Chemical, SUMCO, Global Wafers | The starting substrate for chip production |
| Materials | Photoresist (ArF/EUV) | JSR, Shin-Etsu Chemical, Tokyo Ohka Kogyo | Essential material for advanced lithography |
| Materials | Blank masks | HOYA, ULVAC, and others | The base for fine pattern transfer |
| Equipment | Process equipment and components | Japanese equipment companies | Equipment share second only to the U.S. |
Interpretation: Japan lost finished memory share, but it still controls bottlenecks in materials and equipment. Its leading-edge return is therefore not starting from zero. It is an attempt to climb back up the value chain from existing moats.
3. Rapidus and the public-private model
Rapidus is the symbol of Japan’s return attempt in leading-edge logic. The source mentions Rapidus, LSTC, Samsung Electronics R&D centers, and Japan’s broader research/production hub strategy. The core is aligning public money, R&D, and international cooperation in one direction.
4. Korea’s response: are tax incentives enough?
My core message is the same as the source’s title-level conclusion. Semiconductor investment can lose a speed race if it relies only on tax credits. If Japan uses direct subsidies to attract TSMC and Micron, nurture Rapidus, and support strong materials/equipment suppliers, Korea must improve the cash impact, speed, and predictability of its investment support.
- For large fab investments, Korea should design tax credits and direct subsidies together.
- Materials/equipment firms need customer qualification and mass-production references, not just localization slogans.
- Korea should keep its memory strength while broadening defense lines into back-end process, advanced packaging, power semiconductors, and equipment.
- Cooperation with Japan can be useful, but Korea must avoid overdependence on external bottlenecks.
5. Investor checklist
Direct subsidies
Track how far Korea moves from tax-centered support toward fiscal support.
Rapidus execution
Technology roadmap, customers, yield, and mass-production schedule are the key proof points.
Materials/equipment/packaging
To answer Japan’s moat, actual production references matter for suppliers and packaging companies.
