This appendix provides a comparative summary of Shinzo Abe's (安倍晋三) economic policy, Abenomics (アベノミクス), and Sanae Takaichi's economic policy, Sanaenomics (サナエノミクス). It explains the content, achievements, limitations, similarities, and differences of both policies, as well as the four pillars of the Economic Security Promotion Act.

Abenomics (2012–2020)

Abenomics is an economic policy package introduced with the launch of the second Shinzo Abe Cabinet in December 2012. It was a prescription designed to rescue the Japanese economy from nearly 20 years of deflation and an excessively strong yen (超円高), centered on the core concept of the "Three Arrows (三本の矢)."

The First Arrow: Bold Monetary Easing

The Bank of Japan (BOJ) implemented massive quantitative and qualitative monetary easing. It supplied funds to the market by purchasing government bonds at a scale of approximately 80 trillion yen per year. An official inflation target of 2% was set. In 2016, a negative interest rate policy was also introduced. As a result, it succeeded in driving yen depreciation and rising stock prices. The Nikkei 225 index more than tripled from approximately 8,000 points at the end of 2012 to approximately 27,000 points at the end of 2020.

The Second Arrow: Flexible Fiscal Policy

The 2013 initial budget was significantly expanded, and large-scale public investment was carried out. The economy was stimulated by organizing multiple supplementary budgets. Consumption tax increases (5%→8% in 2014, 10% in 2019) were implemented in stages, with timing adjusted based on economic trends. However, the economic downturn following the 2014 consumption tax hike to 8% is noted as a weakness of Abenomics.

The Third Arrow: Growth Strategy to Encourage Private Investment

The main components included promoting corporate activity through deregulation, expanding female labor force participation under the slogan "A Society Where Women Shine (女性活躍推進)," agricultural reform, and pursuing the TPP (Trans-Pacific Partnership). However, it is evaluated as having the least significant results among the three arrows. Some critics argue that "the third arrow was never actually fired."

Achievements of Abenomics

The Nikkei 225 index more than tripled (approx. 8,000 points in 2012 → approx. 27,000 points in 2020). The unemployment rate fell significantly (4.3% in 2012 → 2.4% in 2019, approaching virtual full employment). Listed companies achieved record-high ordinary profits. Nominal GDP increased (approx. 493 trillion yen in 2012 → approx. 559 trillion yen in 2019, an increase of 66 trillion yen). The economic expansion lasted 71 months (December 2012 to October 2018, the second-longest expansion in the post-war era).

Limitations and Criticisms of Abenomics

Failure to achieve the price target: The 2% inflation target was not consistently met for over 10 years. Price increases following COVID-19 are attributed to external shocks rather than the achievements of Abenomics. Stagnant real wages: Nominal wage growth was minimal, and real wages, adjusted for inflation, even declined at times. Continued fiscal deterioration: The national debt-to-GDP ratio continued to worsen, reaching the world's highest level (over 250%). Income inequality: Pointed out the problem of a "K-shaped recovery," where corporate profits did not translate into wage increases and household consumption. Failure to improve potential growth rate: Structural issues such as low birth rates, population decline, and stagnant productivity remained unresolved.

Sanaenomics (2025–)

Sanaenomics is an economic policy vision that Sanae Takaichi has proposed since her candidacy in the 2021 LDP presidential election. Its most prominent feature is that it inherits Abenomics while adding a new axis of economic security. It consists of the "Three Pillars (三本の柱)."

The First Pillar: Maintaining Expansionary Monetary Policy

Opposition to the Bank of Japan's rapid interest rate hikes and maintaining an easing financial environment. Suppressing excessive strengthening of the yen (円高). During the 2024 presidential election, she expressed a strong stance, even mentioning the potential replacement of the Governor of the Bank of Japan. The policy aims to prevent a regression into deflation and maintain an easing stance until the price target is achieved.

The Second Pillar: Crisis Management Investment

Achieving defense spending of 2% of GDP (meeting NATO standards). Improving disaster response infrastructure (preparing for natural disasters such as earthquakes and tsunamis). Strengthening food security (improving the food self-sufficiency rate). Enhancing energy independence (utilizing renewable energy and nuclear power). This pillar is a concept that did not exist in Abenomics and is an original element of Sanaenomics that integrates economy and security.

The Third Pillar: Growth Investment (Linked with Economic Security)

Concentrated investment through public-private cooperation in advanced strategic fields such as semiconductors, artificial intelligence (AI), quantum computing, space, and biotechnology. Strengthening the operation of the Economic Security Promotion Act. Diversifying supply chains dependent on China and returning production to Japan. Securing domestic production and stockpiling of specific critical materials. This pillar is the newest part of Sanaenomics.

Similarities

Maintenance of monetary easing (prioritizing growth over BOJ independence). Active fiscal spending (checking the Ministry of Finance's fiscal consolidation line). Growth-first philosophy (expanding the economic pie rather than cutting welfare). Strong will for a complete escape from deflation. Policy continuity stemming from the ideological alliance between Abe and Takaichi.

Differences

First, the core role of economic security: While economic security was a secondary theme in Abenomics, it is at the center of the growth strategy in Sanaenomics. Semiconductors, AI, and quantum technology are defined as strategic assets directly linked to national security.

Second, the integration of security and the economy: Defense spending increases are linked to economic growth. The fostering of the defense industry is positioned as a new growth engine.

Third, the centrality of supply chain security: During the Abenomics era, the promotion of globalization and free trade was the main direction, but Sanaenomics emphasizes the domestic production and diversification of supply chains for strategic materials.

Fourth, environmental differences: Abenomics was a policy for the deflationary era, while Sanaenomics is a policy for an era of global inflation and heightened geopolitical risks.

Fifth, emphasis on digital transformation: Sanaenomics positions DX (Digital Transformation) and the utilization of AI as core means of economic growth.

The Four Pillars of the Economic Security Promotion Act

The Economic Security Promotion Act (経済安全保障推進法, enacted in May 2022) is a law that Takaichi led the legislation of as the Minister in charge of Economic Security. It consists of four systems.

The First Pillar: Ensuring Stable Supply of Specific Critical Materials (Supply Chain Resilience): A stable supply system is established by designating materials that are essential for the survival of the people or on which economic activities broadly depend, and which have excessive external dependence, as "Specific Critical Materials." In December 2022, 11 fields were designated: semiconductors, batteries, critical minerals, antibiotics, fertilizers, permanent magnets, machine tools, aircraft parts, cloud programs, natural gas, and ship parts.

The Second Pillar: Ensuring the Stable Provision of Essential Infrastructure Services (Protection of Key Infrastructure): A preliminary screening system for critical equipment is introduced for 14 essential infrastructure industries: electricity, gas, communications, broadcasting, mail, finance, railways, aviation, airports, water, freight, logistics, petroleum. The goal is to prevent infrastructure infiltration by foreign capital or hostile forces. It was fully implemented in May 2024, bringing all four pillars into full operation.

The Third Pillar: Supporting the Development of Advanced Critical Technologies (Prevention of Technology Leakage and Fostering): The government provides funding and promotes public-private collaborative development in advanced technology fields such as AI, quantum technology, biotechnology, space, and cyber. The "Economic Security Critical Technology Fostering Program (K Program)" is the implementation tool for this system.

The Fourth Pillar: Non-disclosure of Patent Applications (Protection of Secret Technology): A system that allows patent applications related to security-sensitive technologies to be kept non-disclosed. This prevents technologies with potential military use from leaking overseas. This system, already in place in major countries, was introduced in Japan for the first time.

Comparison of Key Economic Indicators

Item / End of 2012 (Before Abe) / 2020 (Abe's Resignation) / 2025 (Takaichi's Inauguration)

Yen-Dollar Exchange Rate: Approx. 85 yen / Approx. 104 yen / Approx. 145 yen
Unemployment Rate: 4.3% / 2.8% / 2.5%
Nominal GDP: Approx. 493 trillion yen / Approx. 536 trillion yen / Approx. 600 trillion yen (Est.)
Total Fertility Rate: 1.41 / 1.34 / 1.20 (As of 2023)
National Debt / GDP: Approx. 230% / Approx. 258% / Approx. 265% (Est.)

Note: The Nikkei index and exchange rates are approximate figures around those times, and the figures for Takaichi's inauguration include estimates.

Overall Evaluation

Abenomics achieved numerical results such as rising stock prices, lower unemployment, and increased corporate profits, but left limitations such as insufficient improvement in real wages, fiscal deterioration, and failure to completely escape deflation. Positive evaluations as "the first policy in Japan to implement world-standard macroeconomic policies" coexist with critical evaluations that "the effects were limited compared to the initial conception."

Sanaenomics inherits the legacy of Abenomics but puts the new paradigm of the integration of economy and security at the forefront of policy. In particular, making semiconductors, AI, and supply chain security the core of the growth strategy is evaluated as presenting an economic policy model for the era of geostrategy competition in the 21st century. The core philosophy shared by both policies is that "there is no distribution without growth." It is still an ongoing experiment, and time will tell the results.
