Kyoto's Vacant House Tax and Its National Ripple Effect — Can Tax Policy Reduce Empty Homes?

Kyoto City will introduce Japan's first vacant house tax (Non-Resident Housing Utilization Promotion Tax) starting FY2030. The residential land tax exemption has incentivized vacancy retention for 30 years. This column compares the Kyoto model with the 2023 Special Measures Act amendment, the UK's progressive Council Tax Premium, and France's TLV to structurally analyze the potential and limits of tax-based approaches to the vacancy crisis.

The Core of Japan's Declining Birthrate Is Not Childcare Support: Interrogating the Generational Distribution of 114 Trillion Yen in Social Security

Japan's birth count in 2025 reached 706,000, arriving 17 years ahead of the National Institute of Population and Social Security Research's projection. Yet the root of the problem does not lie in insufficient childcare support. The structural fixation of the declining birthrate stems from an 11-to-1 generational distribution of social security spending: 113.6 trillion yen allocated to the elderly versus 10 trillion yen for children and child-rearing. This article analyzes the "lost opportunity" of the baby-boom junior generation and the democratic circuit that silver democracy has locked shut against any rebalancing.

Corporate Tax as Indirect Tax — How the Defense Surtax Reaches Citizens' Wallets

In April 2026, Japan's Defense Special Corporate Tax took effect — a 4% surtax on base corporate tax liability. Framed as a tax on corporations, its burden ripples through to citizens via price pass-through, supply chain pressure, and a 10-year extension of the reconstruction surtax. This article traces the structural pathways through which the ¥43.5 trillion defense plan's three funding pillars reach household budgets.

Behind a 1.13 Fertility Rate: Why Births Keep Falling Even as Marriages Hold Steady

Japan's estimated total fertility rate for 2025 is 1.13. Despite stable marriage numbers, births continue to decline. The core of this puzzle is a structural turning point around 2015, when the married fertility rate shifted from being a push-up factor to a push-down factor. With completed fertility at a record-low 1.90, reality running 16 years ahead of official projections, and the collapse of the "advanced-nation model" in France and the Nordics, Japan has entered a new phase in which even married couples are choosing not to have children. This article deconstructs the structural mechanisms of this new reality.

Is the Childcare Support Levy a 'Bachelor Tax'? — The Logic and Contradictions of Social Insurance Funding

In April 2026, Japan began collecting a "Childcare Support Levy" as a surcharge on health insurance premiums — payable by all enrollees, including singles and childless households. Dubbed a "bachelor tax" on social media, this article examines the structural debate over social insurance vs. tax-based funding through international comparison with France's CNAF model.

The Structure of Japan's 55% Inheritance Tax — What the World's Highest Rate Really Means

Japan's top inheritance tax rate of 55% is the highest among OECD nations. In 2024, the share of decedents subject to inheritance tax exceeded 10% for the first time, signaling that this is no longer a tax affecting only the wealthy.

Is Babysitter Pay a 'Business Expense'? — The Structural Fault Line in Childcare Tax Deductions

Japan does not allow babysitter costs as a tax-deductible expense. While the US, UK, France, Germany, and Canada all provide tax benefits for childcare expenses, Japan's Income Tax Act classifies childcare as a "household expense" and excludes it from deductions. Ahead of the government's summer 2026 policy review, this article compares international systems and examines the design trade-offs.

Single-Parent Poverty at 44.5%: The Structure Behind 'Working but Still Poor'

Japan's single-parent household relative poverty rate stands at 44.5%. Despite having the highest employment rate in the OECD at 86%, single parents face poverty rates that are among the worst in the developed world. Behind the failure of the 'work hard and you'll be rewarded' premise lies the wage gap in non-regular employment, unpaid child support, and structural limits of the social security system.

Food CPI rose +6.8% year-on-year while the overall index climbed +3.2%. Why do food prices stand out?

Japan's Consumption Tax Regressivity Depends on the Lens — Effective Burden Rates and the Social Insurance Blind Spot

Japan's consumption tax regressivity is a fact on an annual income basis, but some argue it is proportional over a lifetime. Households earning under 3 million yen bear an effective rate of 5.7%, while those earning over 10 million bear just 2.1%. The reduced rate has limited effect, and refundable tax credit discussions are accelerating. Combined with social insurance premium regressivity, we unpack the full picture of structural tax burdens.

Welfare Capture Rates and the 12-Fold Prefectural Gap: A Data-Driven Analysis

Japan's welfare capture rate is estimated at 15–43%. The majority of people who need the system are not reached by it. The welfare receipt rate per 1,000 people ranges from 33.5‰ in Osaka to 2.7‰ in Toyama — a roughly 12-fold gap. Does this disparity reflect the distribution of poverty, or rather differences in accessibility to the system?
