Japan 2026
Japonya
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 electricity.

01 · Readings
Japan in six readings.
Six readings that frame the Japan baseline, and the eight questions this edition answers, each with its status and source.
02 · Sectors
Six sectors, one hexagon.
Water first, then Energy, Infrastructure, Food, Health and Biodiversity. Each count is the findings of this edition in that sector: coverage of the evidence, never a score. Infrastructure is not assessed: the edition holds no Infrastructure finding and its coupling matrix does not assess it.
- WATSu0 findings
2019 Hagibis Share of rivers and supply exposed to typhoon and flood extremes, 2019. □Bildirilen
Ample rainfall but steep, short rivers; flood and landslide risk high; ageing pipes and seismic exposure.

>30% Renewables and nuclear in electricity, FY2023. □Bildirilen
Record-low emissions; >30% clean power; near-total fossil import dependence.
- INFAltyapınot assessed
Dense, ageing networks; strong seismic codes; remote regions fragile.
- FOOGıda1 finding
38% Food self-sufficiency, calorie basis, FY2023. □Bildirilen
38% calorie self-sufficiency; feed and fertiliser largely imported.

97,600 people Heatstroke ambulance transports, May–September, 2024. □Bildirilen
Long life expectancy; heat and ageing load care each summer.

20.5% Land in protected areas, 2023. □Bildirilen
High endemism; protected land about 20.5%, sea about 13.3%.
Outside the six sectors: Climate forcing 2, Finance 1, SEI 2, Systemic 1, Trade 1.
03 · Hazard exposure
The hazards this edition reads.
The edition’s own risk objects, in its order, each read across driver, exposure, vulnerability, capacity, cascade and horizon. The hexagon marks the sectors the cascade reaches; the domain beside each is an editorial reading of its hazard words.

04 · Couplings
How the sectors carry risk into each other.
The Japan matrix types the twenty couplings between the five core sistemleri. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.

| ENE-002 | Japonya | ENE Enerji | □ Bildirilen | Renewables and nuclear together supplied more than 30% of electricity in FY2023; Japan still imports almost all of its fossil fuel. |
| CLI-003 | Japonya | CLI Climate forcing | □ Bildirilen | 2024 was the warmest year on record in Japan; the long-term warming trend is about 1.4 °C per century. |
| SEI-004 | Japonya | SEI SEI | □ Bildirilen | The 2025 revision of the Nankai Trough damage estimate gives up to about 298,000 deaths and ¥292 trillion in damage in the worst case. |
| SEI-005 | Japonya | SEI SEI | □ Bildirilen | The January 2024 Noto Peninsula deprem cut water, roads and care across an ageing region for months. |
| FOO-006 | Japonya | FOO Gıda | □ Bildirilen | Food self-sufficiency was 38% on a calorie basis in FY2023, against a target of 45% by FY2030. |
| HLT-007 | Japonya | HLT Sağlık | □ Bildirilen | About 97,600 people were taken to hospital by ambulance for heatstroke between May and September 2024. |
| HLT-008 | Japonya | HLT Sağlık | □ Bildirilen | 29.3% of the population was aged 65 or over in 2024, and births fell to about 686,000. |
| BIO-009 | Japonya | BIO Biyoçeşitlilik | □ Bildirilen | Protected areas covered about 20.5% of land and 13.3% of the sea in 2023, against 30% by 2030. |
| FIN-010 | Japonya | FIN Finans | □ Bildirilen | About one in three households holds deprem insurance; public infrastructure losses are largely uninsured. |
| TRD-011 | Japonya | TRD Ticaret | ▲ Inferred | Dependence on imported fuel, food and feed makes global price and shipping shocks a direct national risk. |
| SYS-012 | Japonya | SYS Sistemik | ◎ Expert input | The leading compound pathway for 2027 testing is a large earthquake in an ageing region that cuts water, power, roads and care together. |
