Executive summary
The edition on a few pages: the abstract, the key messages, the headline finding and what each steward reads in it.
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.2Key messages
Six readings that frame the Japan baseline, and the eight questions this edition answers, each with its status and source.
1,071 Mt CO₂e in FY2023, 23.3% below FY2013, or 27.1% net of removals.1
Where do emissions stand?Reported
A Nankai Trough megaquake could, in the worst case, cause about 298,000 deaths and ¥292 trillion in damage.9
How exposed is Japan to great earthquakes?Reported
Clean power passed 30%, but almost all fossil fuel is imported.25
How secure is energy supply?Reported
Japan grows 38% of its food on a calorie basis.16
How secure is food?Reported
About 97,600 heatstroke ambulance transports in summer 2024.12
Is heat now a health hazard?Reported
Remote, ageing regions lose water, roads and care at once after a large earthquake.11
What did Noto reveal?Reported
About a third of households hold earthquake cover; public assets are largely uninsured.22
Who carries the losses?Reported
An earthquake in an ageing region cutting water, power, roads and care together. SCN-JPN-EQL-01
What will Q1 2027 test first?Expert input
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.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| 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.4At a glance
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.

Japan’s risk is seismic, climatic and demographic at once
Part I describes systems and their couplings. It assesses no authority and ranks no prefecture.
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?
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.

1.3Twenty couplings between five systems
The Japan matrix types the twenty couplings between the five core systems. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
Each line is one coupling from one system to another, drawn by the strength the edition assigns. Strengths are Nexus estimates from the cited evidence and analogue events.

Key findings
Twelve findings carry the baseline. They are grouped by system, never ranked. Each resolves to its source or, where Nexus analysis is involved, to its stated method.
2.1Headline 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.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Deaths (thousands) | ≈298 | |

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.

4.2Capability ladder
Existence is not readiness. Each of the fifteen capability functions is placed on the ladder by the strongest public evidence at baseline.
| Function | Rung | Level | Strongest public evidence at baseline |
|---|---|---|---|
| Prevention and mitigation | DEMONSTRATED | strict seismic codes credited with limiting building collapse in real events | |
| Monitoring and observation | DEMONSTRATED | dense seismic, tsunami and weather networks in continuous use6 | |
| Early warning | DEMONSTRATED | earthquake early warning and J-Alert in use for real events | |
| Preparedness and planning | TESTED | national drills each year; Nankai Trough advisory issued in August 2024 | |
| Redundancy and reserves | EXISTS | national oil stockpiles; water and food reserves uneven | |
| Response | DEMONSTRATED | Self-Defense Forces and mutual aid in real disasters | |
| Continuity of critical services | EXISTS | Noto showed long water and care outages in remote areas11 | |
| Recovery | EXISTS | reconstruction frameworks; slow in depopulating areas | |
| Adaptation | EXISTS | Climate Change Adaptation Act and plans | |
| Social protection | EXISTS | universal pension and health coverage | |
| Finance and insurance | EXISTS | public–private earthquake insurance; about a third of homes covered22 | |

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.
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

Systems in depth
One section per system: its state at evidence close, its exposures and what the operational series will watch.
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.
| Component | State | Evidence | Status |
|---|---|---|---|
| Supply | ample rainfall; rivers steep and seasonal | 21 | Reported |
| Floods | levee breaches and landslides in heavy rain | 20 | Reported |
| Seismic | pipe failures cut supply after earthquakes | 11 | Reported |
| Ageing pipes | renewal backlog in many utilities | 21 | Inferred |
Couplings into other systems
- WAT → HLT drinking water and sanitation
- SEI → WAT pipe failures
- CLI → WAT heavy rain
- WAT → ENE hydro and cooling
Evidence to bind in 2027
- pipe seismic resilience by utility
- restoration times after earthquakes
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.
| Component | State | Evidence | Status |
|---|---|---|---|
| Power mix | renewables and nuclear above 30% | 2 | Reported |
| Imports | almost all fossil fuel imported by sea | 5 | Reported |
| Nuclear | restarts continuing under safety review | 4 | Reported |
| Peak demand | heat waves raise summer peaks | 12 | Inferred |
Couplings into other systems
- TRD → ENE fuel imports
- ENE → FOO fuel and fertiliser
- CLI → ENE peak demand
- SEI → ENE coastal plant shutdowns
Evidence to bind in 2027
- fuel stock depth under disruption
- grid resilience to great earthquakes
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.
| Component | State | Evidence | Status |
|---|---|---|---|
| Self-sufficiency | 38% on a calorie basis | 16 | Reported |
| Rice | largely self-sufficient; 2024–25 price rise | 17 | Reported |
| Feed and fertiliser | largely imported | 17 | Reported |
| Farm workforce | ageing and shrinking | 17 | Reported |
Couplings into other systems
- TRD → FOO import dependence
- ENE → FOO fuel and fertiliser
- CLI → FOO heat and rice quality
Evidence to bind in 2027
- import concentration by commodity
- heat effects on rice quality
8.4Health and One Health, the baseline system chapter
Japan has long life expectancy and universal coverage, but heat and ageing now load health and care every summer, and disasters hit older people hardest.
| Component | State | Evidence | Status |
|---|---|---|---|

|---|---|---|---|
| Q1 | State and Agenda | What matters this year, and what is the starting position? | observed baseline stays distinct from planned work |
| Q2 | Evidence and Build | What new evidence and capability have been developed? | a configured capability is not a validated result |
| Q3 | Stress Test and Readiness | What do scenarios and tests reveal? | simulated loss or performance is not observed impact |
| Q4 | Annual Synthesis and Renewal | What did the year establish, and what changes next? | release follows review, not event publicity deadlines |

Methodology
How the edition was made: methods, the model card, the evidence cut and its age, the acceptance record and the glossary.
A.1Methods
The baseline uses published values and four simple derivations. Each is shown in full so that any reader can reproduce it.
| No. | Derivation | Calculation | Result |
|---|---|---|---|
| (1) | Net reduction FY2013–FY2023 | 1,395 − 1,017 | 378 Mt |
| (2) | Further cut needed by FY2030 (net) | 1,017 − 0.54 × 1,395 | ≈ 264 Mt |
| (3) | Uncovered share of homes for earthquake | 1 − ≈0.35 | ≈ 65% |
| (4) | Food imported on a calorie basis | 1 − 0.38 | ≈ 62% |
| Strength | Definition |
|---|---|
| STRONG | a disruption in the source system has historically changed the target system’s service or output within one season |
| MODERATE | an effect is documented but buffered or slower |
| WEAK | an effect is plausible but not documented at national scale |
| Label | Rule |
|---|---|

A.7Status words
| Status | What it means |
|---|---|
| Observed | Measured directly and published by the source. |
| Reported | Published statistics of an official or institutional source. |
| Declared | Stated by the body concerned; not independently measured. |
| Estimated | A Nexus estimate from cited evidence, with its method in Annex A. |
| Modelled | Produced by a stated model from cited inputs. |
| Inferred | Reasoned from cited evidence; not measured. |
| Forecast | A projection by the cited source. |
| Simulated | A simulation result under stated assumptions. |
| Scenario | A conditional statement under stated assumptions; never a prediction. |
| Expert input | Expert judgement, recorded with its basis. |
| Candidate | Proposed for a later edition; not yet evidence. |
| Evidence-quality levels (EQL 1 to 5) grade the source behind a value; they are not a score of the subject. | |
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.
| Step | What happens | Source |
|---|---|---|
| 01 Evidence arrives from the pillars | Foundry 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 sealed | On 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 assembled | The edition is drafted from its template and content pack. Agents may draft; they never publish and never decide. | |
| 04 The keys turn | The 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 opens | A 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 deposited | The 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 sites | Only then do the five Reports sites show the edition as published, each reading it through its own lens. | |
| 08 Corrections go to Standards | Method 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).
Lifecycle, one state at a time: Draft, Computed, Evidence bound, Reviewed, Approved for release, Published, Corrected, Superseded. This edition is a draft.

Broken mains left many households without piped water for weeks to months, the defining hardship of the recovery.
WATER
Months without pipes
Cold, displacement and interrupted care raised deaths among older residents after the earthquake itself.
HEALTH AND CARE
Disaster-related deaths
Landslides cut the few roads into the peninsula, delaying relief and supplies.
ROADS
Isolated by the terrain
B.5Japan system card
The card through which Japan appears in the East Asia regional edition and the global series. It summarises; it does not rank.
| System | Baseline state | Coupling to watch | Coverage |
|---|---|---|---|
| Water | steep rivers; seismic pipe exposure | earthquake into care | PARTIAL |
| Energy | clean power >30%; imported fuel | import disruption | GOOD |
| Food | 38% self-sufficiency | import shocks | GOOD |
| Health | ageing; heat | heat and disaster load | GOOD |
| Biodiversity | high endemism | land use and invasives | PARTIAL |
Context
- Archetype
- high-income, ageing island economy with extreme seismic exposure
- Population
- 123.8 million (2024)15
- Trade
- import-dependent for fuel, food and feed516
- Hazard
- Nankai Trough worst case ¥292 trillion9
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.
GLOBAL FLAGSHIP
Peers, not ranks
