What Not to Buy at the 100-Yen Store
Saving money is smart; skimping on your lifeline is not. Five items worth a proper upgrade, with reasons.
The test: what happens if it fails?
As covered in Disaster Prep from 100-Yen Stores, consumables and small items are perfectly fine there. The dividing line is simple: if the item stops working, is there a substitute? Cheap wet wipes never ruin your day; a light that dies within hours of a nighttime blackout has no substitute. These five deserve dedicated products.
1. Power bank
In a disaster your phone is your contact line, news source, flashlight and map all at once. Budget power banks often cannot fully recharge a modern phone even once. With blackouts that can last days, a high-capacity unit that recharges your phone two or three times is the realistic choice. Also check for the PSE safety mark required in Japan.

2. Emergency radio
When a blackout coincides with network outages, radio can become your only news source. What matters is reception quality and redundant power: a dedicated emergency radio that runs on hand-crank, batteries and USB keeps working when everything else is dead. A 100-yen radio is an acceptable backup, not a primary. Emergency radios
3. Headlamp / primary light
During evacuation and nighttime tasks, light quality and runtime translate directly into safety. 100-yen lights excel as room-by-room backups, but your primary light should have published runtime, brightness and water-resistance figures. A headlamp that keeps both hands free is the best first choice. Headlamps
4. Long-life water and bulk emergency food
You can buy water and food at 100-yen stores, but multiplying household size by days quickly becomes a volume problem. Long-life water and emergency food sets are more reliable - and often cheaper per unit - bought in bulk online. Work out your required amounts with the Home Stockpile Checklist. Long-life water
5. First aid and daily medication
Individual bandages from the 100-yen store are fine, but prescription and chronic-condition medicine has no substitute. Keep a copy of your medication notebook and never let your usual medicine run low. A pre-organized first aid kit also saves precious search time. First aid kits

Frequently asked questions
On a tight budget, what comes first?
A high-capacity power bank. It supports communication, information and light with a single purchase.
Are my 100-yen lights wasted?
Not at all. Use them as backups in every room, hallway and toilet, alongside one dedicated primary light.
What is the PSE mark?
A safety label under Japan's Electrical Appliance and Material Safety Act. Check for it when buying power banks.
Can a radio app replace a real radio?
Apps like radiko work only while the network does. An over-the-air radio keeps working through network outages.
How is long-life water different from regular bottled water?
It is produced and bottled for extended storage. Shelf life varies by product, so always check the label.
Where should I buy emergency toilets?
Try one from the 100-yen store, then stock the real quantity in bulk online. The common guide is 5 uses per person per day.
