Welfare

Child Penalty子育て罰（チャイルドペナルティ）: The aggregate economic and social disadvantages incurred by having children, including wage losses (motherhood penalty), increased education and housing costs, and institutional disadvantages. Conceptualized in the Japanese context by Kaori Suetomi and Keita Sakurai.
Care Reimbursement介護報酬: The government-set price paid to care service providers under Japan's Long-Term Care Insurance system. Revised every three years by MHLW, it effectively caps provider revenue and thus directly affects staff wages.
Treatment Improvement Allowance処遇改善加算: An add-on to care reimbursement designed to improve care worker wages. In FY2024, three separate allowances were consolidated into a single 'Care Worker Treatment Improvement Allowance.' Providers must file wage improvement plans and meet career path requirements to qualify.
Relative Poverty相対的貧困: A condition where equivalised disposable income falls below 50% of the median (the poverty line). In the 2021 survey, the poverty line was ¥1.27 million/year. Unlike absolute poverty, it measures the gap from a society's standard of living.

Labor & Employment

Motherhood Penaltyマザーフッドペナルティ: The phenomenon where mothers experience reduced wages, promotion prospects, and labor force participation due to childbirth and childcare. OECD studies show women's earnings drop 20–60% after the first child.
Statistical Discrimination統計的差別: A form of discrimination where individuals are treated based on statistical tendencies of their group rather than individual ability. When employers apply group-level tendencies like 'women are more likely to quit' to individuals, it reproduces gender gaps in hiring, placement, and promotion.
Occupational Segregation職業分離（職種分離）: The concentration of genders in different occupations. Horizontal segregation refers to men and women working in different occupations, while vertical segregation refers to men dominating higher-level positions within organizations. A major structural driver of the gender wage gap.
Working Poorワーキングプア: Workers whose income falls below the poverty line despite being employed. In Japan, single-parent households epitomise this structural problem: their employment rate is the highest in the OECD (86%) while their poverty rate is also among the highest (44.5%).
Standard Monthly Remuneration標準報酬月額: A graded classification of monthly earnings used as the basis for calculating social insurance premiums. Actual salary is mapped to grades 1–50 (for Employees' Pension), and premiums are calculated by applying the rate to the fixed amount for each grade. Revised annually in September based on the average of April–June earnings.

Economy

Residential Land Tax Exemption住宅用地特例: A tax provision that reduces property tax on residential land by up to one-sixth. Since demolishing a vacant house removes this exemption, it creates an economic incentive to leave deteriorating houses standing rather than clearing the land.
National Income (NI)国民所得（NI）: The total income generated by a nation's economic activities. Calculated by subtracting capital depreciation and indirect taxes from GDP, then adding subsidies. Used as the denominator for Japan's national burden rate, though most countries use GDP, making Japan's figures appear higher for the same burden level.
Consumer Price Index (CPI)消費者物価指数: An index that comprehensively measures price changes of goods and services purchased by households. Published monthly by the Statistics Bureau of Japan, it shows price change rates relative to a base year of 100.
Regional Price Parity消費者物価地域差指数: An index comparing regional price levels relative to the national average of 100. Calculated by prefecture and city in the MIC Retail Price Survey. Housing and food costs are the primary drivers of regional variation.
Regressive Tax逆進税: A tax where the burden as a share of income falls more heavily on lower-income groups. Consumption taxes are considered regressive because lower-income households spend a larger share of income on consumption, though some argue they are proportional over a lifetime.
Real Wage実質賃金: A measure of wage purchasing power calculated by dividing nominal wages by the consumer price index. Even if nominal wages rise, real wages decline if prices rise faster.
Cost-Push Inflationコストプッシュインフレ: Inflation caused by rising supply-side costs such as raw materials, energy, labor, and logistics. Because it occurs without demand expansion, wages tend not to keep pace, eroding real purchasing power.
Engel's Coefficientエンゲル係数: The share of food expenditure in total household consumption spending. Generally higher at lower income levels, it serves as a living standard indicator. In Japan, it reached 28.6% in 2025, the highest in 44 years, driven by food price inflation.
Oaxaca-Blinder Decompositionオアハカ＝ブラインダー分解: A statistical method that decomposes wage gaps into a portion explained by differences in observable characteristics and an unexplained portion attributable to discriminatory treatment. Independently proposed by Ronald Oaxaca and Alan Blinder in 1973, widely used in gender wage gap analysis.

Digital & AI

Digital Divideデジタルデバイド: The gap between those who can and cannot use information and communication technologies. It has a three-layer structure: access divide (device/connectivity), skills divide (operational ability), and outcome divide (differential benefits from digital use).
Google for NonprofitsGoogle for Nonprofits: A program offering nonprofits access to Google tools including Ad Grants (up to $10,000/month in search ads), free Google Workspace, and the YouTube Nonprofit Program.
Google Ad GrantsGoogle Ad Grants: A search advertising program within Google for Nonprofits that provides eligible organizations up to $10,000/month in Google Search ads. Requires maintaining CTR above 5% and CPC cap of $2.00.
Click-Through Rate (CTR)CTR（クリック率）: The ratio of clicks to impressions for an ad, calculated as clicks ÷ impressions × 100. Google Ad Grants requires maintaining an account-wide CTR of 5% or higher.
Responsive Search Ads (RSA)レスポンシブ検索広告（RSA）: A Google Ads search ad format that allows up to 15 headlines and 4 descriptions, with Google's machine learning automatically selecting the best combination for each search query. Ad Grants requires at least one RSA per ad group.
Negative Keywordネガティブキーワード（除外キーワード）: Keywords set to prevent ads from showing for specific search terms. They block irrelevant impressions, helping maintain CTR. Essential for Ad Grants compliance with the 5% CTR requirement.
Long-Tail Keywordロングテールキーワード: A specific search phrase of three or more words. Despite lower search volume, long-tail keywords tend to have higher CTR and conversion rates due to clearer search intent. Especially effective under Ad Grants' $2 CPC cap.

Legal & Regulatory

Specified Vacant House特定空家: A designation under the Vacant Houses Special Measures Act for properties posing risks of collapse or sanitation hazards. Designated properties face graduated measures: advice, guidance, recommendation, order, and administrative subrogation.
Management-Deficient Vacant House管理不全空家: A category established by the 2023 amendment to the Vacant Houses Special Measures Act. Refers to inadequately maintained vacant houses at risk of becoming Specified Vacant Houses. Properties receiving recommendations lose their residential land tax exemption.
NPO Corporation (Specified Nonprofit Activities Corporation)NPO法人（特定非営利活動法人）: A corporation established under the Act on Promotion of Specified Nonprofit Activities. It conducts public benefit activities in one or more of 20 designated fields and requires certification from the supervising authority. A minimum of 10 members is required for establishment.
Non-Profit General Incorporated Association非営利型一般社団法人: A general incorporated association whose articles of incorporation ensure non-profit status. By meeting requirements under Article 3 of the Corporation Tax Act Enforcement Order, income from non-profit activities is tax-exempt.
Change of Use用途変更: A procedure under Article 87 of Japan's Building Standards Act for changing a building's designated use. Confirmation application is required when the new use is a special building exceeding 200㎡. For existing non-conforming buildings, compliance with current standards (retroactive application) is required, with fire code and seismic standards creating major practical challenges.
Existing Non-Conforming Building既存不適格建築物: A building that was lawful when constructed but no longer meets current standards due to subsequent law revisions. Unlike illegal construction, continued use is permitted, but compliance with current standards may be required for extensions, renovations, or change of use. Pre-1981 buildings under the old seismic code are the typical example.
Traffic Violation Notification System交通反則通告制度: An administrative system for handling minor traffic violations through payment of fines rather than criminal proceedings, commonly known as the 'blue ticket.' Introduced for motor vehicles in 1968, its scope was expanded to include bicycles from April 2026. Payment of the fine avoids a criminal record, but non-payment triggers criminal proceedings.

Health & Medicine

Polypharmacyポリファーマシー: The concurrent use of multiple medications, generally defined as 5–6 or more drugs. It increases the risk of drug interactions and adverse events, and is a major challenge in geriatric medicine.
Prescribing Cascade処方カスケード: A chain reaction where a drug's side effect is mistaken for a new condition, leading to additional prescriptions. One of the key mechanisms driving polypharmacy.
Adverse Drug Event (ADE)薬物有害事象: Any harmful reaction associated with drug use, including side effects, medication errors, and unintended health consequences from drug interactions. Falls, delirium, and renal impairment are common in the elderly.

Education

Knowledge Gap Hypothesis知識格差仮説: A hypothesis proposed by Tichenor et al. (1970) stating that as mass media information increases, higher socioeconomic groups acquire knowledge faster, widening rather than narrowing the knowledge gap between social strata. A foundational theory showing that more information does not automatically reduce inequality.
Information Poverty情報貧困: A concept theorized by Chatman (1996) through small worlds theory. The information-poor exhibit four characteristics — distrust of outside sources, self-protective secrecy, risk aversion, and situational relevance — that isolate them from available information. A social-psychological mechanism of information exclusion distinct from physical access barriers.
Open Accessオープンアクセス: The practice of making scholarly articles freely available online without restrictions. Launched as an international movement with the 2002 Budapest Open Access Initiative (BOAI). The author-pays Article Processing Charge (APC) model has become dominant, creating new inequalities through cost-shifting.

Psychology

Stress-Diathesis Modelストレス-素因モデル: A theoretical model proposing that suicide risk manifests at the intersection of distal factors (genetic vulnerability) and proximal factors (acute stress).
Internal Working Model内的作業モデル: A mental representation of self and others formed through early attachment experiences. Functions as a lifelong template for interpersonal expectations, emotion regulation, and stress responses; secure versus insecure models produce markedly different relational patterns.
FOMO (Fear of Missing Out)FOMO（取り残される恐怖）: The anxiety or fear that one is missing out on rewarding experiences others are having. A concept increasingly studied in social psychology with the rise of social media, shown to correlate positively with anxious attachment.
Upward Social Comparison上方社会比較: The psychological process of comparing oneself to others who are perceived as superior or more fortunate. Frequently occurs on social media and can lead to relative deprivation and lowered self-evaluation.
Relative Deprivation相対的剥奪感: The subjective sense of injustice that one is not receiving what one deserves. Arising from comparison with others, it can form the psychological basis for hostility and aggressive behavior.
Hostile Attribution Bias敵意帰属バイアス: A cognitive bias toward interpreting others' ambiguous actions as hostile. Associated with insecure attachment styles and relative deprivation, making aggressive responses more likely.
Maslow's Hierarchy of Needsマズローの欲求階層説: A motivational model proposed by Abraham H. Maslow, arranging five levels of need (physiological, safety, love/belonging, esteem, self-actualization) hierarchically. Attachment problems concern the safety (Layer 2) and love/belonging (Layer 3) levels — more fundamental than the esteem needs (Layer 4) often conflated with them.
False Consensus Effect偽の合意効果: A cognitive bias where people overestimate the extent to which others share their beliefs, behaviors, and judgments. Named by Ross et al. (1977); a meta-analysis of 115 tests confirmed an effect size of r=0.31.
Selective Exposure選択的接触: The tendency to preferentially consume information consistent with one's existing attitudes and beliefs. A behavioral manifestation of confirmation bias, prominently observed in social media comment and news consumption.
UCLA Loneliness ScaleUCLA孤独感尺度: A psychological scale developed at UCLA to measure loneliness. Characteristically avoids using the word 'lonely' directly, instead indirectly assessing the lack of social connection. Adopted in Japan's national loneliness surveys.

Cognitive Science

Sensory Processing Sensitivity感覚処理感受性: A temperamental trait characterized by lower neural response thresholds to environmental stimuli. Found in an estimated 15–20% of the population and studied as the biological basis of Highly Sensitive Persons (HSP).
Metacognitionメタ認知: "Cognition about cognition" — the ability to observe and evaluate what you are thinking and why. Defined by Flavell (1979) and widely studied as a foundation for self-regulation, learning, and decision-making.
Variable Ratio Reinforcement Schedule変動比率強化スケジュール: A reinforcement condition where rewards are delivered at irregular intervals. Produces the most extinction-resistant behavior patterns and is a core concept explaining the addictiveness of slot machines and social media infinite scroll.
Doomscrollingドゥームスクローリング: The compulsive consumption of negative news and content. The amygdala's threat-scanning and dopamine's information reward form a feedback loop, evoking anxiety and existential dread.
Agnotologyアグノトロジー（無知学）: The study of how ignorance is produced and maintained. Systematized by Robert Proctor in 2008. Analyzes the absence of knowledge not as a natural state but as a social product actively manufactured by industry, power, and institutions. The tobacco industry's manufacture of doubt is the canonical case.
Epistemic Injustice認識的不正義: A concept proposed by Miranda Fricker in 2007, referring to injustice in the production and circulation of knowledge. It takes two forms: (1) testimonial injustice, where a speaker's testimony is wrongly discredited due to prejudice, and (2) hermeneutical injustice, where an experience goes unrecognized because society lacks the concepts to articulate it.

Genetics

Epigeneticsエピジェネティクス: Changes in gene expression that occur without alterations to the DNA sequence. Environmental stress can rewrite gene switches through mechanisms such as DNA methylation.
Candidate Gene Hypothesis候補遺伝子仮説: The hypothesis that specific genes are directly involved in mental illness or behavioral traits. Border et al. (2019) refuted the candidate gene hypothesis for depression in a large-scale study.
Polygenicポリジェニック（多遺伝子性）: A trait determined by the cumulative small effects of many genetic variants. Mental illness and suicide risk are highly polygenic.
Genome-Wide Association Study (GWAS)ゲノムワイド関連解析: A method that uses genetic data from hundreds of thousands to millions of people to comprehensively search for genetic variants associated with specific diseases or traits.
5-HTTLPR (Serotonin Transporter Gene Polymorphism)セロトニントランスポーター遺伝子多型: A polymorphism in the gene involved in serotonin reuptake. S-allele (short form) carriers were thought to have higher anxiety, but this has been refuted by large-scale studies.
Differential Susceptibility Hypothesis (Orchid-Dandelion)差次感受性仮説: The hypothesis that individuals with certain genetic predispositions are maladaptive in adverse environments but more adaptive in favorable ones. Also known as the 'Orchid and Dandelion' hypothesis.
Genetic Determinism遺伝決定論: The view that genes unilaterally determine behavior and traits. Considered scientifically inaccurate in modern genetics.
Heritability遺伝率: The proportion of phenotypic variation in a population attributable to genetic factors. It indicates the relative ease of environmental intervention in a particular society, not the immutability of genetic traits.
DNA MethylationDNAメチル化: A chemical modification where methyl groups are added to DNA molecules. One of the primary epigenetic mechanisms that suppresses gene expression.

Public Health

Means Restriction手段制限: An approach to suicide prevention that physically limits access to specific methods of suicide. Examples include platform doors, pesticide regulation, and bridge safety nets.
Means Substitution手段代替: The phenomenon where restricting one method of suicide leads to switching to another method. Meta-analyses across 62 countries confirm that complete substitution rarely occurs.
Randomized Controlled Trial (RCT)ランダム化比較試験: An experimental design that randomly assigns participants to intervention and control groups to test effectiveness. One of the highest-quality methods of evidence generation.
Social Prescribing社会的処方: A practice where healthcare providers 'prescribe' participation in community activities and social resources rather than medication. Institutionalized in the UK NHS with link workers connecting patients to community resources. Gaining international attention as a loneliness countermeasure.
Health Literacyヘルスリテラシー: The ability to obtain, understand, evaluate, and apply health information. Nutbeam (2000) proposed a three-level model: functional (reading/writing), interactive (social skills for eliciting information), and critical (analytical assessment and autonomous use). A framework demonstrating that information availability alone is insufficient.

Public Policy

Evidence-Based Policy MakingEBPM: An approach to policy making and evaluation based on objective evidence such as statistical data and research findings.
Post-Normal Scienceポスト・ノーマルサイエンス: A framework in science studies proposed by Funtowicz & Ravetz (1993). In situations of high uncertainty, high stakes, and urgent decisions, normal scientific procedures alone are insufficient; knowledge co-production by an extended peer community (including citizens and stakeholders) is required.
Logic Modelロジックモデル: A framework that visually maps the causal relationships from inputs to activities, outputs, and outcomes of a program.
Theory of Change (ToC)セオリー・オブ・チェンジ: A planning method that works backward from long-term social change goals to specify necessary intermediate outcomes and causal pathways of intervention.
Collective Impactコレクティブインパクト: A framework where multiple sectors (government, business, NPOs, etc.) collaborate under a shared agenda to address social issues.
Social Return on Investment (SROI)社会的投資収益率: A social impact evaluation method that converts social, environmental, and economic outcomes into monetary values and expresses them as a ratio to input costs.
Non-Take-Up制度の非捕捉（ノンテイクアップ）: The situation where eligible individuals do not access welfare benefits they qualify for. Japan's public assistance take-up rate is estimated at approximately 22.9%.
Nudgeナッジ: A technique that guides people's behavior in desirable directions by adjusting defaults and information presentation while preserving freedom of choice.
Build Back Betterビルド・バック・ベター: A principle that views disaster recovery not as mere restoration but as an opportunity to overcome societal vulnerabilities and build a more resilient society. Established as one of four priority actions in the 2015 Sendai Framework for Disaster Risk Reduction.
Refundable Tax Credit給付付き税額控除: A tax credit system where the excess amount beyond tax liability is paid out as cash. Adopted in many countries to mitigate consumption tax regressivity, including Canada's GST/HST Credit and the US EITC. Japan began formal discussions on implementation in 2026.
Dormant Deposits休眠預金: Bank deposits with no transactions for 10 or more years. Under Japan's Dormant Deposits Utilization Act (effective 2018), these funds are channeled to private-sector public interest activities through JANPIA as the designated fund distribution organization.
Asset Management (Infrastructure)アセットマネジメント: A systematic approach to assessing infrastructure condition, predicting deterioration, and prioritizing renewal within limited budgets to optimally maintain facility functions. In water utilities, tracking pipe aging rates and replacement rates forms the foundation.
Concessionコンセッション方式: A PFI method where the government retains ownership of public facilities while delegating operational rights to private operators. In water utilities, Miyagi Prefecture became Japan's first adopter in 2022.
Pipe Aging Rate管路経年化率: The proportion of pipelines exceeding their statutory useful life (40 years for water pipes). As of FY2022, the national average reached 23.6%, projected to rise to approximately 69% by 2042 at the current replacement pace.
Disability Pension障害年金: A public pension paid to individuals whose daily life or work is restricted due to illness or injury. It consists of Disability Basic Pension (Grades 1–2) and Disability Employees' Pension (Grades 1–3). Eligibility requires meeting three conditions: first medical examination date, premium payment, and disability status.
First Medical Examination Date初診日: The date of the first medical consultation for the condition causing the disability. It serves as the starting point for determining disability pension eligibility. A structural problem arises when medical records exceed the 5-year retention period, making proof difficult.
Medical Model of Disability障害の医学モデル: An approach that views disability as an impairment of individual bodily functions, with medical treatment as the solution. Contrasts with the social model. Japan's disability pension certification criteria have been criticized for relying on this model.
Representative Democracy代表制民主主義: A form of democracy in which citizens make political decisions through elected representatives. Contrasted with direct democracy, it resolves the problem of scale while being based on the principle of popular sovereignty, though the gap between representatives and voters is a persistent challenge.
Political Efficacy政治的有効性感覚: The subjective belief that one's political participation can influence politics. Divided into internal efficacy (belief in one's ability to understand and participate in politics) and external efficacy (belief that government responds to citizens). A major determinant of voter turnout and political participation.
Small Concessionスモールコンセッション: A small-scale PPP/PFI initiative (typically under 1 billion yen) for revitalizing underused public properties such as vacant houses and abandoned schools. MLIT established a dedicated platform in 2024.
Park-PFIPark-PFI（公募設置管理制度）: A system under Japan's Urban Parks Act that publicly solicits private operators to develop and manage revenue-generating facilities (e.g., cafés) alongside park facilities. Established by 2017 law revision with up to 20-year permits.
Public-Private Partnership / Private Finance InitiativePPP/PFI: An umbrella term for public-private collaboration in delivering public services and managing public infrastructure. PFI specifically leverages private finance for infrastructure, while PPP encompasses PFI plus designated manager systems and comprehensive outsourcing.
Sounding (Market Survey)サウンディング型市場調査: A dialogue-based market survey conducted before public tender to gather private sector opinions and ideas on utilizing public assets. Used to pre-validate feasibility and appropriate conditions.
Designated Manager System指定管理者制度: A system under Japan's Local Autonomy Act that allows private operators and NPOs to manage public facilities. Introduced in 2003 to improve efficiency and service quality, though typically short designation periods (3-5 years) can hinder long-term investment.
Fiscal Capacity Index財政力指数: An index measuring a local government's fiscal strength, calculated as the 3-year average of standard fiscal revenue divided by standard fiscal demand. Municipalities scoring 1.0+ are non-grant recipients. A fundamental metric for assessing fiscal capacity when selecting PPP/PFI methods.
Kaigyo (Marine Industry)海業（うみぎょう）: An umbrella term for businesses that leverage the value and appeal of marine and fishing village resources to meet diverse domestic and international needs, generating local vitality, income, and employment. Institutionalized as 'Fishery Port Facility Utilization Business' in the 2023 amended Fisheries Port Act. Includes experience tourism, direct sales, dining, and aquaculture.

Sociology

Cherry Pickingチェリーピッキング: The practice of selectively presenting only favorable portions of data. By arbitrarily choosing time periods, subjects, or variables, diametrically opposite conclusions can be drawn from the same dataset.
Confounding Variable交絡変数: A third variable that influences both variables under study. Overlooking confounding variables leads to mistaking spurious correlations for causal relationships.
Proxemicsプロクセミクス: The study of how humans perceive and manage interpersonal distance. Cultural anthropologist Edward T. Hall systematized four zones (intimate, personal, social, public) in 1966.
Contact Culture接触文化: Cultural groups where physical touch and close interpersonal distances are common in communication. Includes Southern Europe, the Middle East, and Latin America, contrasted with non-contact cultures (Northern Europe, East Asia).
Social Inclusion社会的包摂: Efforts to ensure that people marginalized by poverty, discrimination, or disability can participate in and benefit from society. The counterpart of social exclusion.
Emotional Labor感情労働: A form of labor requiring workers to manage and suppress their own emotions while displaying organizationally appropriate expressions. Coined by sociologist Arlie Hochschild, it is prominent in care work, nursing, and service industries, and is a major contributor to burnout.
Matthew Effectマタイ効果: A concept of cumulative advantage named by Merton (1968), derived from Matthew 25:29 ('For to everyone who has, more will be given'). Originally describing recognition bias in science, it applies to education, information access, and economic inequality — initial advantages compound over time.
