S.1Abstract

Japan enters 2027 with record-low emissions, a shrinking and ageing population and one of the world’s most demanding hazard regimes. Greenhouse-gas emissions fell to 1,071 Mt CO₂e in FY2023, 23.3% below FY2013 and 27.1% lower once forest removals are counted, as renewables and nuclear together passed 30% of electricity12. The country has set reductions of 60% by FY2035 and 73% by FY2040 against FY20133. Yet Japan still imports almost all of its fuel, grows only 38% of its food on a calorie basis16 and faces a Nankai Trough megaquake that the national evaluation puts at a high probability within thirty years10. 2024 was the warmest year on record7, heatstroke sent about 97,600 people to hospital by ambulance in the summer of 202412, and the January 2024 Noto Peninsula earthquake showed how an ageing, remote region loses water, roads and care at once11. This Baseline Edition fixes the reference state for Japan’s water, energy, food, health and biodiversity systems, maps the couplings through which seismic, climate and supply shocks travel, and sets the questions the first operational edition will answer with Foundry evidence in Q1 2027. It ranks nothing and decides nothing.

S.3Headline finding

ReportedEQL 4NRF-COUNTRY-JPN-2026-BASELINE-SEI-004

The 2025 revision of the Nankai Trough damage estimate gives a worst case of about 298,000 deaths and ¥292 trillion in damage, with tsunami the leading cause of death.

Figure S.1Nankai Trough worst-case estimate (2025 revision)
ItemBar, scaled to the largest valueValue
Deaths (thousands)≈298
Damage (¥ trillion)≈292

Source: Central Disaster Management Council working group9.

Such an event would strike the Pacific industrial belt, ports, refineries and power plants at once, and the national economy and global supply chains through them. Early evacuation and seismic retrofitting are estimated to cut deaths sharply, which makes preparedness a high-value capability89.

S.5What each steward reads in it

GCRI · KEY T

Technical Truth

The evidence supports a coupled reading of Japan’s risk: great earthquakes dominate the tail, climate extremes are rising, and ageing magnifies both.

GRF · KEY M

Public Meaning

For most people risk arrives as an earthquake alert, a heat wave or a typhoon warning.

GRA · KEY F

Capital Meaning

Readiness implications only. About a third of homes hold earthquake cover, public assets are largely uninsured, and climate disclosure standards apply from 2025.

NEXUS

Synthesis

Japan is strong at warning and response and thinner at keeping water, care and supply running for weeks.

S.6What this edition is, and is not

What this edition is

A baseline: the state of Japan’s water, energy, food, health and biodiversity systems in 2026, the dependencies that connect them, the risks that travel through them and the capabilities that hold them. It sets out the questions the operational series will answer.

What it is not

Not a national risk assessment, an official warning or a rating. It decides nothing about any institution or asset. Competent authorities keep every mandate they hold, and national ownership of the series is unaffected.

What comes next

Q1 2027 opens the operational series with a sealed Foundry evidence cut. Each later edition reports what changed against this baseline, new observations, source revisions, method changes, scenario updates and corrections.

1.1The questions this part answers

Key questions

  • Where is Japan’s risk concentrated, and in which systems?
  • Which couplings carry shocks from one system to the next?
  • Which capabilities hold under compound stress, and which are only documented?
  • What must the 2027 programme measure first?

1.2The argument

Japan is usually described as the most disaster-prepared country in the world, and in many respects it is. This baseline reads its exposure as three slow and fast forces acting together: great earthquakes and tsunamis, a warming climate that intensifies heat and rain, and a population that is shrinking and ageing faster than almost any other.

The seismic layer dominates the tail. The 2025 revision of the Nankai Trough estimate puts worst-case losses at about 298,000 deaths and ¥292 trillion in damage9, and the national evaluation keeps the probability of such an event within thirty years high10. The Noto Peninsula earthquake of January 2024 showed the shape of the risk in miniature: water, roads, power and care failed together in a remote, ageing region, and heavy rain struck the same area again in September11.

The climate layer is rising. 2024 was the warmest year on record, and the long-term trend is about 1.4 °C per century67. About 97,600 people were taken to hospital by ambulance for heatstroke in the summer of 202412, and heavy-rain disasters such as Typhoon Hagibis in 2019 have breached levees at scale20.

The demographic layer changes everything else. 29.3% of the population is 65 or over, and births fell to about 686,000 in 20241415. An older, smaller population means more people who need help to evacuate, fewer workers to respond, and rural infrastructure that is harder to maintain.

Beneath all three sits import dependence. Japan imports almost all of its fossil fuel and grows only 38% of its food on a calorie basis516. Emissions have fallen to a record low, and renewables and nuclear passed 30% of electricity in FY202312, but energy and food security still depend on sea lanes and world prices.

This edition therefore reads Japan’s risk as a property of the couplings between these forces. The matrix, risk objects, capability ladder and scenario that follow ask the same two questions: where does a shock travel next, and who holds the capability to stop it?

Figure 1.1How far has Japan cut emissions, and how far is left? Emissions and targets (Mt CO₂e)

Net emissions fell by 378 Mt between FY2013 and FY2023. About 257 Mt more must go by FY2030, two-thirds of a decade’s progress in seven years13.

Implication

Such an event would strike the Pacific industrial belt, ports, refineries and power plants at once, and the national economy and global supply chains through them. Early evacuation and seismic retrofitting are estimated to cut deaths sharply, which makes preparedness a high-value capability89.

What would move it

Progress on tsunami evacuation towers and retrofits, the next long-term evaluation, and business-continuity coverage along the Pacific coast would each move this finding.

Great earthquake in an ageing region

A conditional statement under stated assumptions, never a prediction.

Lenses and readings

The baseline is read through each steward’s lens, then once as a whole. Each lens is a projection of reviewed findings, not a separate argument.

8 min read0 figures6 tables27 notesNR-COUNTRY-JPN-2026-BASELINE

6.1Three lenses

One edition, read by each steward. The lens of this site comes first.

GRF · KEY M

Public Meaning

For most people risk arrives as an earthquake alert, a heat wave or a typhoon warning. The baseline asks that public debate weigh how an older, smaller population changes who can evacuate, who can respond and how fast places recover.

HLT-007 · HLT-008 · SEI-005

GCRI · KEY T

Technical Truth

The evidence supports a coupled reading of Japan’s risk: great earthquakes dominate the tail, climate extremes are rising, and ageing magnifies both. Evidence is strongest for emissions, hazards and early warning, and weakest for lifeline–care continuity and digital dependencies.

CLI-001 · SEI-004 · SEI-005 · SYS-012

GRA · KEY F

Capital Meaning

Readiness implications only. About a third of homes hold earthquake cover, public assets are largely uninsured, and climate disclosure standards apply from 202526. These show where finance-readiness evidence will matter. Nothing here is advice, a rating or an approval.

FIN-010 · SEI-004

NEXUS

Synthesis

Japan is strong at warning and response and thinner at keeping water, care and supply running for weeks. The 2027 programme should map lifeline–care dependencies, test the Noto pattern at scale, and measure fuel and food import exposure.

SYS-012 · A-01 · A-02

6.2Global Risks Forum reading: editorial essays

Four signed essays by the Reports editorial team set out the positions this edition takes. They are interpretation, labelled as such; the evidence they draw on is in the findings register.

Japan prepares for earthquakes better than anyone, yet a Nankai Trough event remains the largest single loss the country could face. The baseline treats it as a coupling problem, ports, plants and care all at once, not as a building-code problem alone.

EDITORIAL ESSAY · 01

The long tail is seismic

An older, smaller population does not change the earthquake; it changes who can leave, who can help and which villages are rebuilt. Every risk object in this edition is read through that lens.

EDITORIAL ESSAY · 02

Ageing is a hazard multiplier

Japan’s clean-power progress is real, but fuel, food and feed still arrive by sea. Energy and food security are trade questions as much as domestic ones.

EDITORIAL ESSAY · 03

Security is imported

Earthquakes are rare; heat now arrives every summer. Ambulance transports for heatstroke show a slow-motion disaster concentrated among older people living alone.

EDITORIAL ESSAY · 04

Heat is the new everyday disaster

8.1Water, the baseline system chapter

Japan has ample rainfall but steep, short rivers, so water arrives fast and leaves fast. Floods, landslides and seismic damage to pipes are the binding risks.

8.2Energy, the baseline system chapter

Emissions are at a record low and clean power passed 30% of electricity in FY2023, but Japan still imports almost all of its oil, gas and coal.

8.3Food and agrifood, the baseline system chapter

Japan grows 38% of its food on a calorie basis, and much of its feed and fertiliser is imported, so food security is a trade question.

A.8How the edition is made, released and corrected

Every edition is built from a sealed evidence cut, reviewed under three keys, signed and deposited before any site shows it as published; corrections go to Nexus Standards as change proposals and feed the next cut.

StepWhat happensSource
01 Evidence arrives from the pillarsFoundry seals observations and indicator series, Universe hands over after-action and scenario findings, and contributions are screened at every gateway, including this site’s.
02 The cut is sealedOn the cut date the evidence is pinned under one identifier, so anyone can rebuild the edition from exactly what it was built on.
03 The edition is assembledThe edition is drafted from its template and content pack. Agents may draft; they never publish and never decide.
04 The keys turnThe Global Risks Forum turns the meaning key: its steward checks that each finding is said without overreach, endorsement or judgement of public figures. No edition moves on until every key has been turned by a named steward.
05 The gate opensA named approver releases one exact digest of the edition; any change after this point is a new version, never a silent edit.
06 Signed and depositedThe PDF, the web edition and the data bundle are signed together with a manifest and an RO-Crate description, and deposited on Zenodo with a concept and a version DOI.
07 Published on five sitesOnly then do the five Reports sites show the edition as published, each reading it through its own lens.
08 Corrections go to StandardsMethod and correction findings go to Nexus Standards as change proposals; citations, corrections and new contributions feed the next evidence cut.

A teaching model of the process, not a forecast and not a record of any run; dates and counts on this page come from the programme record. Sources: Reports governance at Global Risks Forum (2026); Zenodo, repository of record for Reports deposits (2026).

Japan’s card sits beside its neighbours’; shared basins, grids, corridors and supply chains are read as one regional system.

EAST ASIA REGIONAL EDITION

One regional system

Japanese evidence enters the water, energy, food, finance and climate sector reports through the same finding identifiers, so a correction travels everywhere at once.

GLOBAL SECTOR SERIES

Same findings, same IDs

In the global edition Japan is read against peer distributions and thresholds, never placed in a league table.

Search the open indexes for Japan; software is cited by its SWHID from Software Heritage, and a quantified scenario run is preregistered on OSF before it is run. Annotation is your choice: Hypothesis opens this page in its own viewer.

Mirrors and harvest

The DOI is canonical. At release each signed bundle is also given an IPFS content identifier and a bloxberg anchor as mirrors; both are listed in the record once they exist. Zenodo exposes every record over OAI-PMH, and reviews and endorsements can arrive through COAR Notify where the repository supports it.

C.5Where this edition sits among the six pillars

Foundry seals the evidence and Universe tests it; Reports publishes it; Standards takes its corrections and Academy teaches from it.

  1. F03 Sealed observations and indicator series Foundry Sealed observations and indicator series behind a profile (closeout).
  2. F04 After-action and scenario findings for Universe After-action and scenario findings for chapters 10 and 13 (after action review).
  3. F05 National Portfolio movement for chapter Foundry National Portfolio movement for chapter 11 (after action review).
  4. Applied in editions Standards Nexus Standards: applied in editions.
  5. JPN edition Reports Japan 2026, published in every format with its sources, citation and corrections.
  6. F06 Method and correction findings as change Standards Method and correction findings as change proposals (correction).
  7. F12 Q4 synthesis informs the next-year Universe Q4 synthesis informs the next-year mandate (renewal).
  8. Taught in the open Academy Risk Academy: taught in the open.

What Foundry and Universe hand to this edition, and what it hands to Standards, Universe and Academy. From the programme spine; JPN is a drafted Baseline Edition, so these handoffs run from its first operational quarter.
