What are the common misunderstandings about looking after a leather jacket?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
A leather jacket is talked about as "something you wear for decades", yet "it went mouldy", "it went stiff" and "it shrank at the cleaner's" are common failures. Japan's humidity is the key factor. Here we sort out the types of leather, daily care, storage and cleaning with that climate in mind.
Care and storage
| Situation | What to do | Why |
|---|---|---|
| After wearing | Brush off dust with a soft brush or dry cloth; hang on a broad, padded hanger overnight in the shade | Lets sweat and moisture out |
| Rain | Press dry at once with a dry cloth, reshape and dry in the shade. No hairdryer or heater | Sudden heat stiffens and shrinks leather |
| Once or twice a year | A thin layer of leather cream (a "delicate cream" or similar), tested first on a hidden spot. Not on suede or nubuck | Replaces oils |
| Storage (spring to autumn) | Breathable non-woven cover, broad hanger, control humidity in the closet (dehumidifier packs, open it now and then), keep moth repellent from touching the leather | Mould is the greatest enemy |
| If mould appears | Wipe with a dry cloth and air outdoors in the shade. Rubbing alcohol (消毒用エタノール, shōdoku-yō etanōru) may lift the colour — test on a hidden spot. Widespread mould: specialist leather cleaner | — |
| Cleaning | Not an ordinary dry cleaner but a leather specialist (皮革クリーニング, hikaku kurīningu). Several thousand to over ¥10,000; ask them to explain the risk of shrinkage and colour change | Solvents and water alter leather |
| Creases and stiffness | Wearing it brings it back. Steam only lightly, held off the surface (not suitable for every leather) | — |
- Leather jackets are covered by the Household Goods Quality Labelling Act, so they carry the type of leather (cowhide, sheepskin, horsehide, etc.). Sheepskin (lambskin) is soft but damages easily; cowhide is tough.
- The conditions for mould (humidity above 70%, 20–30°C / 68–86°F) are easily met in a Japanese closet (see the article on closet humidity). Take the jacket out and air it once before the rainy season (tsuyu) and once in autumn.
- Cleaning problems (shrinkage, colour change) are among the complaints received by the National Consumer Affairs Center of Japan, and leather is classed as a special item under the industry's "Dry-cleaning Accident Compensation Standards" (see the dry-cleaning article).
[Verify] Check the labelling duty against Consumer Affairs Agency materials, and the leather-cleaning cautions against the Japan Federation of Dry Cleaning Associations and the Japan Leather and Leather Goods Industries Association.
Misunderstanding 1｜Leather is tough, so it needs nothing
Mould in humidity, cracks when dry, fading in sunlight. Brush and air after wearing; cream once or twice a year.
Misunderstanding 2｜It is safe in the closet
A Japanese closet meets all the conditions for mould. Breathable cover, dehumidifier packs, air it now and then. Never plastic.
Misunderstanding 3｜Dry cleaning will bring it back to new
Ordinary dry cleaning is unsuited to leather; risk of shrinkage and colour change. Go to a leather specialist and have the risks explained.
Misunderstanding 4｜Dry rain off with a hairdryer
Sudden heat stiffens, shrinks and cracks the leather. Press dry, reshape, and air in the shade for one to two days.
Misunderstanding 5｜More cream makes the leather softer
Too much makes it sticky, feeds mould and dulls the colour. Thinly, once or twice a year. Not on suede.
