Japan 2026

اليابان

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.

  • 123.8millionpopulation, October 2024 [15]
  • 29.3%aged 65 or over [15]
  • 1,071Mt CO₂eemissions, FY2023 [1]
  • 38%food self-sufficiency (calories) [16]
  • ≈15%energy self-sufficiency, FY2023 [5]
  • 47prefecturesin eight regions

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.

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.

Great earthquake in an ageing region

Under this scenario, results describe a conditional season under stated assumptions. It is not a forecast, and no intervention described here has been carried out.

04 · Couplings

How the sectors carry risk into each other.

The Japan matrix types the twenty couplings between the five core النظم. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
