A home kit can afford to be heavy. A tsunami bag has one job: let you move uphill quickly while helping a child, a pet, or someone with mobility needs. Everything that fights that job comes out.

Quick answer. The most important tsunami item is not in the bag — it is the route. If you are near the coast and feel strong or long shaking, see the ocean suddenly rise or fall, or hear an unusual roar, move inland or to higher ground immediately. A nearby tsunami can arrive before any phone alert.
That opening changes the packing logic completely, so it is worth stating plainly before any list: a tsunami go-bag is a mobility tool, not a warehouse. Weight you cannot carry uphill at speed is weight working against you.
Do not invent a universal elevation number from the internet. Use your local evacuation zone and the official destination — the safe height in one town is not the safe height in another.
Put the finished bag on and walk the route. If it slows you, hurts, unbalances you, or stops you carrying a child or a pet carrier, it is too heavy or badly fitted. This test fails more bags than any packing list.
Keep the bag near the exit, not buried in a closet.
Enough for the initial evacuation, while the larger reserve stays at home. Sealed bottles or a leak-resistant container.
Medication, glasses, hearing supplies, inhalers, mobility accessories, and a paper medical summary. Plan temperature-sensitive medicines with a clinician.
There may be broken glass and debris on the route. If you normally spend time barefoot near the beach, the shoes must be attached to or inside the bag.
Night evacuations need hands-free light. Add spare batteries or a charged backup.
A charged power bank and the correct short cable. Download the local evacuation map for offline use — you may be moving through an area with no service.
Official instructions and the all-clear continue after cell service fails.
Immediate cuts, dressings, gloves and particulate masks. A lightweight evacuation kit is not a field hospital and should not be packed like one.
Protected copies, paper contacts, policy numbers, and smaller denominations. Do not carry an unencrypted password list.
A light rain shell, a warm layer, sun protection or heat supplies — whichever your local climate and season actually demand.
Infant feeding supplies, nappies, mobility equipment, sensory or communication aids. Every household’s bag should look different, and yours looking unusual is not a mistake.
Carrier or secure harness, leash, water, collapsible bowl, medication, waste bags, identification and a recent photo. Practise loading the animal before you ever need to.
Build the route, assign the people and the pets, then carry only what helps you move and wait safely. A bag that fails the carry test is not a safety measure — it is a delay you packed yourself.
| Do | Avoid |
|---|---|
| Treat strong or long shaking as the warning | Waiting for a siren or a phone alert |
| Walk the official route in daylight first | Guessing a safe elevation from the internet |
| Keep the bag light enough to carry uphill | Packing the home kit and calling it a go-bag |
| Keep it by the exit | Storing it at the back of a closet |
| Wait for the official all-clear | Returning to the shore to look |
