Koromogae (衣替え) is the Japanese custom of swapping the wardrobe over between seasons. It is usually thought of as a swapping job. In practice it is a job of preparing clothes for storage — and in a climate as humid as Japan's, that preparation decides what you find when you open the box.
| Step | Stage | Basis |
|---|---|---|
| 1 | Wash everything you are putting away | Invisible sebum and sweat cause yellowing and odour during storage |
| 2 | Dry completely | Sealed away damp, bacteria start to multiply in about 5 hours (findings on the bacteria behind the "indoor-drying smell", 部屋干し臭, of laundry dried indoors) |
| 3 | Check for damage and fit; decide what to let go | Saves storage space |
| 4 | Put away on a low-humidity day, with air able to circulate | Do not seal moisture in with the clothes |
For washing, follow the care label (Japan uses the international JIS L0001 symbols, in force since December 2016; the August 2024 revision brought the set to 43 symbols).
[Verify] The care-label system is from Consumer Affairs Agency material. Check before publication.
Invisible sebum and sweat remain. They are generally described as the cause of yellowing and odour during storage.
Seal things up on a humid day and you seal in the moisture too. Choose a dry day.
Some materials lose their shape. Check the care label.
Some moth repellents (防虫剤, bōchūzai) cannot be used together. Check the label and keep to the stated amount.
The climate is changing. There is no need to fix the number of times or the timing.
