What do people get wrong about the household first-aid box (kyūkyūbako)?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Most Japanese homes keep a first-aid box, historically restocked by a visiting salesman (the "okigusuri" system that still exists in some regions). What goes in it, and what does not, reflects a country where a clinic is usually nearby and self-medication is regulated.
A typical box
| Category | Contents | Note |
|---|---|---|
| Wounds | Adhesive dressings (several sizes), sterile gauze, non-stick pads, tape, elastic bandage, hydrocolloid dressings (widely used), disinfectant or saline, tweezers, small scissors | Wash wounds under running water first — the current guidance |
| Fever / pain | Thermometer, acetaminophen (adults and a children's formulation), cooling gel sheets | Aspirin not given to children |
| Stomach | Oral rehydration solution (sachets or bottles), antidiarrhoeal only as directed, digestive aid | ORS matters for children and elderly |
| Other | Antihistamine (OTC), eye wash, motion-sickness tablets, hot/cold packs, disposable gloves, mask | — |
| Paper | Copies of health-insurance cards, clinic and pharmacy numbers, #7119 / #8000 / 119 written down, medication list | For anyone in the house — or a babysitter |
| Check | Every 1 March and 1 September (with the emergency kit); discard expired items | Dates on OTC boxes |
- OTC medicines in Japan are classed 1–3 (see the OTC article); keep them in their boxes with the package insert — dosage and age limits are printed there.
- Children's medicine is dosed by age and weight; keep a children's acetaminophen product rather than splitting adult tablets.
- #7119 (emergency consultation), #8000 (children, nights and weekends) and 119 (ambulance) are the three numbers; poison information: Japan Poison Information Center 072-727-2499 (Osaka) / 029-852-9999 (Tsukuba).
- The okigusuri (placed medicine) system — a box left in the home and restocked by a visiting vendor, paid for on use — dates from the Edo period in Toyama and still serves rural households.

Misunderstanding 1｜Stock it like a pharmacy
A clinic is usually within walking distance and open six days a week. The box handles the first hour; it is not for treating illness at home over days.
Misunderstanding 2｜Disinfectant first on every cut
Current guidance is running water first, then a clean dressing; strong disinfectants on healthy tissue are used less than a generation ago. Deep, dirty or animal-bite wounds go to a clinic.
Misunderstanding 3｜Adult medicine, half dose, for children
Children's formulations exist for a reason (dose by weight, safe ingredients). Keep one, with its insert, and check the age limit.
Misunderstanding 4｜The box is set up once
Dressings dry out, tablets expire, children grow into new dose bands. Twice a year, with the emergency kit (1 March, 1 September), is the household rhythm.
Misunderstanding 5｜Everyone knows where it is
Put it where a guest or babysitter could find it — a labelled box in the kitchen or living room, out of children's reach, not in a bedroom drawer. Tape the three emergency numbers to the lid.
