Umbrella Etiquette (傘立てマナー - Kasatate)
The rule of placing your wet umbrella in the rack or using a disposable plastic sleeve at store entrances. Prevents slippery floors and guards against umbrella mix-ups.
Rooted in keeping shared floors clean and dry. Since clear vinyl umbrellas look identical, taking the wrong umbrella by mistake is extremely common; adding unique markers is highly recommended.
Ask a store representative if you should leave your umbrella outside in the collective stand or use a bag.
