Official-source starting point
Yokohama guidance separates spray cans into a transparent or translucent bag and asks residents to empty contents safely away from fire.
Owned safety seed
Yokohama spray-can disposal guide
A focused safety guide for Yokohama residents unsure whether spray cans need puncturing, can/bottle collection, or burnable-waste-day separation.
Demand evidence
Why this surface exists
Search confusion
Search results show residents asking whether puncturing is needed and whether spray cans belong with cans, bottles, and PET bottles. The weekday and safety steps get mixed together.
This validation step
Sort Day does not replace official guidance. It measures municipality, spray-can condition, confusion reason, and contact as source=yokohama-spray-can-disposal.
Operating flow
Three steps without mixing hazards
Identify the can and contents
Separate aerosol cans, cassette gas cylinders, styling-product cans, remaining contents, and cap handling.
Keep puncture guidance official
Never push unsafe puncturing. The page keeps residents pointed to the latest Yokohama source.
Separate from normal cans
Do not mix can/bottle/PET recycling with the spray-can-only bag workflow.
