WHO 2018 Environmental Noise Guidelines vs. Japan's Standards — What a Gap of Up to 25 dB Actually Means
The WHO Regional Office for Europe's 2018 environmental noise guidelines identify road noise at Lden 53 dB and above as raising the risk of heart attack and stroke, and recommend nighttime Lnight below 40 dB. Japan's environmental quality standards permit 45 dB at night in residential zones and 65 dB at night along arterial roads. This note reads the gap against the health-effects research.
Soundproofing Subsidies Choose Their Roads — The Disparity Structure of the Roadside Housing Soundproofing Program
Subsidies for soundproofing works exist for residential properties along arterial roads, but eligibility is subject to compound conditions including designated routes, year of construction, and application timing. This note examines the structural dynamic in which residents suffering equivalent noise harm are nonetheless excluded from subsidy coverage.
Why Victims Stay Silent — The Social Psychology Behind the Failure of Collective Noise Complaints
Residents suffering from traffic noise remain stuck at individual complaints and never organize collectively. Behind this pattern lie the free-rider problem — 'someone else will act' — learned helplessness, and a thin sense of standing among people who are 'just trying to live normally.' This note examines the psychological mechanisms that produce complaint gap zones.
The Learning Curve of Nine Noise Lawsuits — From the Tolerable Limit Doctrine to a ¥5.9 Billion Verdict
From the Supreme Court's 1967 tolerable limit doctrine to the Yokohama District Court's 2024 Fifth Atsugi Base Noise Lawsuit awarding approximately ¥5.9 billion in damages, Japan's noise litigation has evolved from individual grievances with token compensation to mass-plaintiff suits producing verdicts in the hundreds of millions. Nine cases, one learning curve.
Integrating Climate Justice and Social Policy — A Design Guide
A guide to the 'just transition' framework for designing climate action and social welfare policy in an integrated manner.
Those Living Along Arterial Roads Bear the Greatest Noise Burden — An Environmental Justice Hypothesis for Japan
Low-income households and persons with disabilities tend to concentrate in affordable housing along arterial roads, and the severity of noise exposure is inversely proportional to income. While international theoretical frameworks are well established, empirical evidence in Japan is nonexistent. This note examines the structure in which the regulatory framework itself reserves more lenient standards and longer grace periods for arterial roadsides.
Four Research Hypotheses and Verification Plan
Formulating the relationship between urban noise and sensory stress into four research hypotheses. Identifying research gaps in sensory-sensitive individuals × outdoor routes, zoning × noise disparity, complaint void zones, and context-dependent stress, presenting a Phase 0-3 verification roadmap.
