Overview

I conduct a comparative analysis of policies and manifestos for the upcoming 51st House of Representatives election using generative AI. The purpose of this article is not to judge the merits of the policies, but to help understand the differences between them and assist in voting behavior.

Author’s Stance

While I have my own thoughts and vision for the future, I do not support any specific political party. I aim to make this analysis useful for voters, including myself, through comparative analysis. Therefore, I will use AI to provide neutral evaluations, focusing on facilitating and visualizing the policies themselves rather than judging their quality. The interpretation of information and voting behavior are matters of personal judgment, and I believe everyone should vote freely in accordance with democratic principles. My starting point was a desire to make confusing politics understandable through comparison so that I could vote in a way that satisfies me, and I hope that readers will be able to do the same. Note that some may find discrepancies or feel uncomfortable with the analysis depending on their own views and positions. In such cases, I encourage you to investigate and verify for yourself, which will lead to the goal of this article: voting with conviction. Please use any discomfort as a catalyst for your own investigation rather than leaving it unresolved. I would be happy if the analysis itself is used to assist individual judgment and the analysis of personal thoughts, rather than supporting or opposing specific parties.

Analysis Method

I input the latest policies of each party and the manifestos summarized by NHK as files and use the following prompt for analysis. For Team Future, since their policies are detailed on GitHub, I attach the policies listed on GitHub as a substitute.

<role>
You are an expert in policy analysis. You can objectively extract facts from diverse perspectives across ages and positions to grasp policy trends.
Your role is not to judge the merits of policies based on specific individuals, positions, or ideologies, but to convey accurate information based on facts from a neutral standpoint so that it provides useful information for voters in voting.
</role>

<request>
Analyze the political party's policies from the attached file and output them according to the output format.
</request>

<tenets>
* Each political party considers policies with diverse ways of thinking for people in all positions. Avoid personal attacks or emotional criticism, respect the described policy intentions, but strictly evaluate logical consistency.
* Evaluate the realizability of policies strictly based on facts.
* Do not judge the merits of policies but output objectively based on facts.
</tenets>

<rule>
* Treat the attached files as facts and review the political party's policy proposals.
* When describing the reason for evaluation (reason), cite and refer to which description in the attached file is the basis as concretely as possible.
* Basically ignore information that is difficult to read from the attached file. This is because it is considered difficult for voters to understand and difficult to guarantee accurate reading and quality due to the quality and nature of the materials.
  * If information not in the attached file is unknown, clearly state that it is unknown. Do not analyze that information.
  * If there is information not in the attached file that is common knowledge, include it in your analysis based on your knowledge.

The analysis format is as follows:

• Evaluation of each field as a percentage and reasons for scoring
  • Human Rights
  • Childcare
  • Labor
  • Elderly
  • Disability Welfare
  • Diplomacy / Security
  • Economy
  • Environment
  • DX / Science and Technology
  • Constitutional Amendment
• Financial Resources and Method of Realization
• Realizability
• Party Stance and Reason
  • Left-Right Coordinate X (-5: Left, 0: Center, 5: Right)
  • Up-Down Coordinate Y (5: Liberal, 0: Center, 5: Authoritarian) Note: The prompt says -5 Liberal / 5 Authoritarian in schema, matching common charts.

The reason for setting these is to allow for multi-faceted comparisons considering various ages, positions, and ways of thinking, and to provide an opportunity to consider their validity. I use AI to evaluate and compare using these formats. The model used is Gemini 3 Pro in thinking mode for complex reasoning. The Q&A session is limited to once.

Analysis

This chapter primarily presents the results of the AI analysis. Please check Senkyo WEB for each party’s pledges.

Liberal Democratic Party (LDP)

I use the information from Announcement of pledges for the general election: “Making the Japanese Archipelago Strong and Rich” as the attached file.

Human Rights (Score: 70)

While showing a stance of adhering to universal values such as freedom, democracy, and the rule of law, they pledge to eradicate sexual crimes and violence, tackle harassment, address business and human rights, and resolve the abduction issue. On the other hand, from the perspective of economic security and cyber security, measures focused on national security, such as measures regarding data storage and processing and strengthening information gathering, are also prominent.

Childcare (Score: 90)

Based on the “Acceleration Plan” of 3.6 trillion yen, they state they will steadily implement substantial expansion of child allowance, reduction of higher education costs, and strengthening of housing support. They also show a stance of strongly promoting economic support and environmental improvement, such as providing 100,000 yen per child (Note: text says 20,000 yen in JP but common pledges vary, sticking to translation: “20,000 yen per child”), free standard childbirth costs, and free school lunches.

Labor (Score: 80)

They aim to establish wage increases that exceed price rises, accelerating minimum wage hikes and promoting labor-saving investments. Thorough implementation of equal pay for equal work, addressing work disincentives by raising the “annual income wall” to 1.78 million yen, and wage increases through significant reward hikes in medical, nursing, and welfare fields are specified.

Elderly (Score: 75)

They pledge to secure a sustainable medical provision system through regional medical concepts, measures against dementia, and promotion of nursing care services outside public insurance. They also aim for a society where the elderly can be active by establishing a support system for elderly people without relatives to live with peace of mind and promoting “aggressive preventive medicine” to extend healthy life expectancy.

Disability Welfare (Score: 75)

They pledge to realize community life according to the diverse needs of people with disabilities, enhance special needs education, and promote the placement of medical care nursing staff. Toward the realization of an inclusive society, environmental improvements for people with and without disabilities to enjoy culture, arts, and sports are also included.

Diplomacy / Security (Score: 15)

It is a hawkish stance that regards the Japan-US alliance as the cornerstone and drastically strengthens defense capabilities. They focus on improving deterrence and building a security system, such as abolishing the 5 categories of operation guidelines for the Three Principles on Transfer of Defense Equipment, securing sustainability capabilities, revising the “Three Documents” including the National Security Strategy, and establishing a National Intelligence Bureau.

Economy (Score: 75)

Advocating “responsible active fiscal policy,” they tend towards “big government” with large-scale fiscal spending on crisis management investment and growth investment. In addition to over 150 trillion yen of public-private investment in GX and concentrated investment in strategic fields such as AI and semiconductors, they intend aggressive fiscal intervention, such as abolishing provisional tax rates like gasoline tax as a measure against high prices and considering tax exemption for food products for two years.

Environment (Score: 80)

They position GX (Green Transformation) as a pillar of growth toward achieving carbon neutrality by 2050. They aim to balance decarbonization and economic growth through technological innovation, such as promoting the restart of nuclear power plants and development of next-generation innovative reactors, expanding the introduction of perovskite solar cells and offshore wind power, and establishing a manufacturing base for 150GWh/year of storage batteries.

DX / Science and Technology (Score: 95)

Aiming to be the “world’s most AI-friendly country,” they state they will concentrate investment on advanced technologies such as AI, semiconductors, and quantum. They prioritize solving issues through thorough DX and science and technology across society, including expanding functions and utilization of My Number cards, digitizing administrative and judicial procedures, decentralized location of data centers, and introducing Beyond 5G.

Constitutional Amendment (Score: 90)

They regard constitutional amendment as a “party tenet since its founding” and aim to realize amendments centered on four items: clarification of the Self-Defense Forces, emergency response, dissolution of combined electoral districts, and enhancement of education early. They are eager to draft clauses in the Commission on the Constitution and conduct a national referendum, strongly advocating for a review of the constitution to suit the times.

Financial Resources and Method of Realization

Based on “fiscal policy premised on the economy,” they aim for a virtuous cycle of growth through investment and increased tax revenue. Instead of relying on supplementary budgets, they will establish a “new budget framework for investment” in the initial budget to enable flexible multi-year spending. Support targets are allocated with emphasis on labor-saving and growth investment for SMEs, direct benefits to child-rearing households, wage increases for medical and nursing care workers, and strategic industries such as AI and semiconductors.

Realizability (Score: 85)

Investment plans accompanied by specific amounts are shown, such as 150 trillion yen for GX, 3.6 trillion yen for children’s policies, and 1 trillion yen for the space strategy fund. Specific administrative and legal processes for realization, such as legal amendments (Basic Act on Ocean Policy, Insurance Business Act, Construction Business Act, etc.) and the establishment of new organizations (Disaster Prevention Agency, National Intelligence Bureau), are also specified, so realistic execution ability is evaluated as high.

Party Stance

Left-Right Coordinate (X: 4)

A hawkish stance emphasizing conservative values and strengthening national sovereignty is clear, such as the development of strong defense capabilities, priority on maintaining male-line succession in imperial succession, and strong promotion of constitutional amendment. On the other hand, they also have aspects of populism or revised capitalism, such as considering provisional tax exemptions for consumption tax and large-scale fiscal spending.

Up-Down Coordinate (Y: 3)

Authoritarian tendencies emphasizing state management/surveillance and maintenance of social order are seen, such as drastic strengthening of intelligence functions, introduction of land acquisition regulations, expansion of My Number system utilization, and strict dealing with illegal residents. On the other hand, liberal aspects that enhance individual convenience, such as expanding individual choices through DX and work style reform, are also listed.

Centrist Reform Coalition (CRAJ)

I use the PDF version of basic policies as reference material.

Human Rights (Score: 85)

They pledge extremely specific progressive policies regarding sexual minorities and gender equality, such as realizing selective separate surnames for married couples, enacting same-sex marriage (Marriage Equality Act), and enacting an LGBT Discrimination Elimination Act. In addition, a stance emphasizing individual dignity and human rights from multiple perspectives is clear, such as enacting a Refugee Protection Act, correcting “hostage justice,” and creating an independent human rights redress institution.

Childcare (Score: 90)

Pledging to “support without breaks from pregnancy/childbirth until the child leaves the nest,” economic burden reduction measures are very generous and specific, such as free prenatal checkups and childbirth costs, expansion of child allowance until age 18 and increase to 15,000 yen per month, and free pre-school education and nursing care including 0-2 year olds. They also focus on protecting children’s rights, such as support for young carers and the establishment of a “Children’s Commissioner.”

Labor (Score: 85)

Aiming to raise the minimum wage to over 1,500 yen nationwide early, they specify a review of labor laws to make regular employment the principle and support for introducing a 3-day work week. Furthermore, they emphasize policies that directly improve workers’ quality of life and take-home pay, such as guaranteeing the “right to disconnect” and raising the treatment of essential workers to the all-industry average.

Elderly (Score: 75)

By aiming to “abolish the mandatory retirement age,” they are promoting the development of an environment where willing elderly people can continue to work. They also present policies from both aspects of peace of mind in life and social participation, such as additional pension benefits for low-income elderly people, review of the pension for working elderly, and development of regional medical systems for those with difficulty moving using online medical care.

Disability Welfare (Score: 80)

They pledge to review the revision of rewards for disability welfare services and raise the salaries of workers to the all-industry average. Concrete mentions are also made of improving accessibility to remove physical and institutional barriers (social barriers), such as introducing discounts for people with mental disabilities, making small shops barrier-free, and promoting inclusive disaster prevention.

Diplomacy / Security (Score: 45)

While maintaining realistic security such as strengthening deterrence within the scope of defensive defense and regarding the exercise of the right of self-defense in existential crisis situations as “constitutional” based on the Japan-US alliance, they also emphasize the role of bridging dialogue and disarmament (a nuclear-free world), such as observing the Treaty on the Prohibition of Nuclear Weapons and leading multilateral security dialogue in Northeast Asia, taking a balanced stance between realism and idealism.

Economy (Score: 85)

They prioritize large-scale redistribution to households and livelihood support through fiscal spending, such as making “zero consumption tax on food” permanent, introducing “tax credits with benefits,” and lowering social insurance premiums. They aim for “big government” economic management that plans to raise the bottom up for low and middle-income groups, advocating “Consumers First” rather than market competition.

Environment (Score: 90)

Pledging to maximize the introduction of renewable energy and realize carbon neutrality early, they aim for a “society not dependent on nuclear power” in the future. They also prioritize environmental protection extremely highly as one of the pillars of economic growth, incorporating the realization of “Nature Positive” and regional revitalization through a circular economy.

DX / Science and Technology (Score: 80)

They state they will promote R&D of cutting-edge technologies such as domestic support for cloud and AI, photoelectric fusion, and nuclear fusion as national projects. Also, the policy to actively utilize digital technology for the efficiency of administration and social services, such as medical DX, ICT in nursing care offices, and introduction of internet voting, is clear.

Constitutional Amendment (Score: 60)

While adhering to constitutionalism and basic principles, they state they will deepen “responsible constitutional amendment discussions” based on discussions on the “position of the Self-Defense Forces in the Constitution.” They also mention clarification of the “right of dissolution” of the House of Representatives, showing a positive attitude toward constitutional amendment as legal maintenance responding to the demands of the times, without clinging to the status quo (protecting the constitution).

Financial Resources and Method of Realization

They state they will secure new financial resources by creating a government-affiliated fund (Japan Fund) and utilizing existing funds and revising rules. These resources will be allocated to zero consumption tax on food, tax credits with benefits, reduction of social insurance premiums, free education and childcare, and investment in priority fields such as green and digital.

Realizability (Score: 65)

They present unique financial resource securing measures such as “government-affiliated funds” and “utilization of funds,” and pledge policies accompanied by specific numerical targets such as zero consumption tax on food and increased child allowance. On the other hand, regarding whether financial resources such as fund investment profits can be secured stably in a short period against huge fiscal demands such as zero consumption tax and reduction of social insurance premiums, more detailed simulations are awaited.

Party Stance

Left-Right Coordinate (X: -1)

While the party name includes “Centrist” and they take a realistic line (conservative aspect) emphasizing the Japan-US alliance in security, policies such as zero consumption tax on food, protection of human rights such as LGBT, selective separate surnames, and large-scale redistribution are strongly liberal/leftist, so overall they are located in a slightly leftist “Center-Left” coordinate.

Up-Down Coordinate (Y: -3)

They strongly promote “thorough decentralization/local autonomy,” diversity of individual work styles (3-day work week, etc.), gender equality, and guarantee of minority rights. It is a “Liberal” stance emphasizing the expansion of individual choices, inclusion of diversity, and decentralization of power rather than uniform control by the state.

Japan Innovation Party (Ishin)

I use the core manifesto and the PDF for the 51st House of Representatives election from this link as materials.

Human Rights (Score: 75)

They aim to allow same-sex marriage for sexual minorities such as LGBTQ and introduce a partnership system (Japanese version of PACS) that can be used not only between same-sex couples. They also show a positive attitude toward individual rights protection, such as banning hate speech based on ethnicity or nationality, total visualization of interrogations, and institutionalizing the presence of lawyers. On the other hand, they also have aspects emphasizing national security, such as enacting an anti-espionage law and strengthening intelligence functions.

Childcare (Score: 95)

They pledge childcare and education support with extremely high priority, such as free education for all courses without income restrictions, free school lunches for elementary and junior high schools, and completely free early childhood education and childcare for ages 0-2. Furthermore, they incorporate multi-layered policies aimed at reducing economic burdens, such as effective free childbirth costs, introduction of the “N-th power N-th method” (income splitting), and restoration of the youth dependency deduction.

Labor (Score: 60)

Advocating “Flexicurity (Flexibility + Security),” they assert balancing employment liquidity with safety net improvement and raising the minimum wage. While thorough equal pay for equal work, support for the employment ice age generation, and shifting to job-type employment are included, emphasis is basically placed on improving the labor environment through market revitalization via deregulation.

Elderly (Score: 45)

The main focus is on reducing the insurance premium burden on the working generation through social security reform, aiming to raise the medical expense window burden for elderly people with certain income to 30% in principle (equivalent to the working generation). While promoting employment and activity of the elderly such as extending healthy life expectancy and reviewing the pension for working elderly, the content also involves increased burdens according to assets and income for the sustainability of the system.

Disability Welfare (Score: 70)

They propose employment support utilizing technology, a legal employment rate system, and the introduction of a flexible mechanism to evaluate order amounts to freelancers and offices. They also specifically mention promotion of agriculture-welfare coordination, consistent medical and educational support for children with disabilities, and improvement of information accessibility in administrative services.

Diplomacy / Security (Score: 15)

They emphasize drastic strengthening of defense capabilities and intelligence functions, such as shifting from “defensive defense” to “active defense,” possessing long-range missiles and submarines equipped with counterattack capabilities, and enacting an anti-espionage law. Drastic review of the Japan-US Status of Forces Agreement is also pledged, but the basic stance is placed on securing national independence and security through strengthening military deterrence.

Economy (Score: 25)

There is a strong “small government” orientation emphasizing promotion of market competition, deregulation, and thorough expenditure reduction. While pledging zero consumption tax on food for two years and reduction of social insurance premiums, they also aim for a primary balance surplus. However, redistribution mechanisms such as negative income tax, basic income, and tax credits with benefits are also included as a future vision.

Environment (Score: 55)

While pledging to achieve carbon neutrality by 2050, considering the reality of economic burden, the policy is to proceed with early restart of nuclear power plants and introduction of renewable energy such as geothermal. They position the decarbonization field as a new growth industry and emphasize balancing economic growth and environmental protection.

DX / Science and Technology (Score: 98)

They promote rationalization of the entire society through technology extremely strongly throughout, including thorough DX of administration, full utilization of AI, rationalization of tax collection and benefits by linking My Number with bank accounts, diffusion of electronic medical records, and realization of internet voting using blockchain.

Constitutional Amendment (Score: 90)

They strongly promote constitutional amendment in a wide range of items as the party’s fundamental policy, including free education, specifying self-defense rights and a national defense force in Article 9, shifting from local autonomy to “regional sovereignty,” establishing a Constitutional Court, and creating an emergency clause.

Financial Resources and Method of Realization

They utilize waste reduction by the “Government Efficiency Bureau” and “Special Taxation Measures and Subsidy Review Office,” and optimization of medical expenses including reduction of unnecessary hospital beds (target of 4 trillion yen reduction) as financial resources. The policy is to allocate these resources intensively to direct support for child-rearing households (free education, school lunches, medical care), reduction of social insurance premiums for the working generation, and investment in defense and science and technology.

Realizability (Score: 65)

They present specific policy items as “12 Arrows” based on the coalition agreement with the LDP, and some have schedules and target timings indicated, such as a 10% reduction in the number of Diet members and enactment of the Vice Capital Bill. On the other hand, huge political and social adjustments are necessary for the 4 trillion yen reduction in medical expenses, drastic transformation of the social security system, and realization of constitutional amendment, and uncertain elements remain in the execution process.

Party Stance

Left-Right Coordinate (X: 3)

They are right-wing/conservative in emphasizing economic liberalism, deregulation, and strengthening defense capabilities, but can be said to be a center-right reform party as they actively incorporate liberal elements in social policy, such as substantial response to selective separate surnames, acceptance of same-sex marriage, and the basic income concept.

Up-Down Coordinate (Y: -3)

They are liberal (countering authority) in strongly demanding thorough decentralization (DO-shu system/regional sovereignty), dispersion of power through the “Vice Capital” concept, and transparency and efficiency of administration. On the other hand, they also have aspects seeking strengthening of state functions in public order and security, such as strengthening national intelligence and anti-espionage laws.

Democratic Party for the People (DPFP)

I use the pamphlet on the special site as reference material.

Human Rights (Score: 85)

They launch human rights protection from multi-faceted perspectives, such as specifying human rights that must not be restricted even under a state of emergency, eliminating discrimination based on sexual orientation and gender identity, considering same-sex marriage, and further establishing “data self-sovereignty” in a digital society.
