Half-used cosmetics, old sunscreen, nail polish, aerosol cans — many people are unsure how to throw them away, and foreign residents often ask which bin cosmetics go in under Japan's waste-sorting rules. Sorting rules are set by each municipality (市区町村) and differ from town to town. Here we set out the general principles and how to handle the hazardous items (aerosols, nail-polish remover).
| Item | Contents | Container | Watch out for |
|---|---|---|---|
| Toner, milk, other liquids | Soak into newspaper or old cloth and put in burnable waste (可燃ごみ). Do not pour down the drain (oils and other ingredients) | Plastic → plastic recycling or burnable; glass → glass; pumps sorted separately (metal spring) | Some municipalities allow small amounts to go with burnable waste |
| Creams and solids (lipstick, foundation) | Wipe onto paper and put in burnable waste | As above | — |
| Powders | Bag it and put in burnable waste | — | Stop the powder flying about |
| Nail polish and remover | Soak remover into paper, let it dry outdoors, then burnable waste (flammable and volatile). Let nail polish harden, or wipe it onto paper | Glass bottles go with glass (some municipalities class unwashable bottles as non-burnable) | Keep well away from flames; ventilate |
| Perfume | Soak into paper and put in burnable waste. For large amounts, ask the municipality | Glass | High alcohol content; keep away from flames |
| Aerosol cans (hairspray, antiperspirant, sunscreen) | Use up the contents (outdoors, away from flames). Whether to puncture depends on your municipality's instructions (more and more now say "do not puncture") | Varies by municipality: aerosol collection day, non-burnable, or recyclables | Fires in collection trucks from cans with contents left inside happen across Japan |
| Hair dye | Do not mix parts 1 and 2; soak each into paper and put in burnable waste | Containers sorted by material | Mixing causes a reaction and heat |
| Unopened or barely used, still fresh | Consider reuse (collection boxes, donation) | — | Some shops and organisations collect them |
[Verify] Your own municipality's sorting rules take priority over everything here. Check the aerosol-fire cases and warnings against Ministry of the Environment materials.
In most municipalities, empty the contents and sort the container by material. Soak liquids into paper and put them in burnable waste.
Oils and other ingredients burden sewage treatment; remover and perfume are flammable. Soak into paper.
Many municipalities have switched to "do not puncture" (to prevent accidents while puncturing). Using up the contents is common to all. Check your municipality's instructions.
Mixing parts 1 and 2 causes a reaction and heat. Soak each into paper separately.
Unopened items in good condition can be collected or donated (in-store at makers, NPOs). Opened items cannot be reused for hygiene reasons, so buying less in the first place is the real fix.
