Disaster Prep from Japan's 100-Yen Stores
What Daiso, Seria and Can Do can cover - and the few items worth a proper upgrade.
The short answer: they cover a lot, but not everything
If cost is what keeps you from starting your disaster prep, Japan's 100-yen stores are your best friend. Daiso, Seria and Can Do stock far more usable emergency gear than most people expect. The winning strategy: build the foundation at the 100-yen store, then upgrade only the handful of items where performance is critical.
Stock varies by store and season, so treat the lists below as "commonly found staples" rather than guarantees.
What 100-yen stores cover well, by category

- Wet wipes and sanitizing sheets
- Portable toilet bags (small packs) and coagulant
- Masks, tooth-cleaning wipes, dry shampoo
- Trash bags and plastic bags of every size
Food and water

- Canned and retort food (a cheap entry into rolling stock)
Warmth, protection and misc.

- Work gloves, whistles, compression bags, waterproof cases
- Curing tape and permanent markers (for messages and labeling)
Where to spend real money instead
For the following items, capacity and reliability directly affect your safety, so a dedicated product is worth it. The reasoning is covered in detail in What Not to Buy at the 100-Yen Store.
Power bank: capacity and safety matter most. One high-capacity unit that recharges a phone several times is the anchor of your kit. Power banks
Emergency radio: your information lifeline in a blackout. Hand-crank models with a built-in light are the standard choice. Emergency radios
Long-life water and bulk emergency food: easier and more reliable to buy in volume online. Long-life water
Headlamp: hands-free light is the workhorse of any evacuation. Check runtime and water resistance. Headlamps
A 3-step plan for 100-yen prep
- Bring a list: check what you are missing with the Go-Bag Checklist before you go - it keeps impulse buys in check.
- Start with consumables: wet wipes, trash bags, batteries - things you replace anyway are a perfect match for 100-yen stores.
- Upgrade the core: power bank, radio and water from dedicated brands. Your total cost still stays low.
