Japan is one of the world's biggest consumers of umbrellas: around 120–130 million a year, many of them the clear plastic kind (ビニール傘, binīru-gasa) sold at every convenience store. Here is the know-how for keeping an umbrella out of the bin, and how its water repellency can be brought back.
| Item | Figure / content |
|---|---|
| Umbrellas consumed in Japan per year | About 120–130 million (estimate by the Japan Umbrella Promotion Association). More than one per person per year |
| Share that are disposable plastic umbrellas | Estimated at around half |
| How the repellent finish works | Fine fluorine- or silicone-based pile on the fabric surface repels water. When dirt and friction flatten the pile, it stops working |
| How to revive it | ① Dry it ② Hairdryer on warm (low), held 10–20 cm away (raises the pile) ③ Water-repellent spray (outdoors) |
[Verify] Check the consumption figures against material published by the Japan Umbrella Promotion Association (JUPA). The explanation of repellency is a general one from textile finishing.
An umbrella with solid ribs and fabric can last 10 years with care. The mass disposal of plastic umbrellas is raised as a problem in Ministry of the Environment material too.
Dirt and flattened pile are the main cause. First dry it and use a hairdryer on warm. If water still does not bead, repellent spray.
Closed while wet, the inside never dries: mould, rust and smell. Open it in the entrance hall to dry. If you want to dry it in the shared areas of a block of flats, check the building's rules first.
You can rinse the fabric and wash it lightly with a sponge and diluted neutral detergent. Rubbing removes the repellent finish, so only press. Wipe rust on the ribs with a cloth and dry.
A single broken rib can be fixed with a splice piece (a repair part). The parts are sold at 100-yen shops and DIY stores, and some shops and repair events take umbrellas.
