Japan’s March 2026 volcanic-ash leaflet sets out household supply checklist
A Cabinet Office and Japan Meteorological Agency leaflet explains ashfall disruption and recommends about one week of supplies for potentially prolonged living at home.
The checklist pairs food, water and everyday essentials with dust masks, protective goggles and ash-cleanup equipment.
What changed
A dated hazard-specific publication, not evidence of an imminent eruption.
Who this is for
Residents in areas that could experience ashfall.
What the official guidance says
- Consult local hazard maps and evacuation plans as well as the supply checklist.
Dates & context
Remaining at home is conditional: dangerous ash accumulation, debris-flow risk or unmet care needs can require evacuation. The leaflet does not establish a changed all-hazards national stockpiling rule.
