In rainy Japan, you cannot avoid a leather bag getting wet at some point. "What do I do once it's wet?" and "does waterproofing spray damage leather?" are asked in every country. Once you know what a rain mark actually is, the way you respond changes.
| Situation | Do | Don't |
|---|---|---|
| Just wet | Press with a soft dry cloth to lift the water (don't rub). If only part of it is wet, lightly dampen the whole bag with a wet towel to remove the boundary (prevents rain marks) | Leaving it, hair dryer |
| Drying | Stuff it with paper to hold the shape; 1–2 days in a well-ventilated shady spot | Direct sun, heater |
| Once dry | A thin layer of leather cream (the oils have been lost) | Over-applying |
| Prevention | Fluorine-based waterproofing spray (フッ素系防水スプレー), outdoors, 30 cm away, two thin coats. Test on a hidden spot | Spraying indoors (inhalation accidents) |
| By material | Suede and nubuck: a spray made for them; patent leather: no spray, just wipe; synthetic leather: resists water but hydrolyses | Cream on suede |
[Verify] Check waterproofing-spray accidents against the National Consumer Affairs Center's published material. Care methods are based on guidance from the Japan Leather and Leather Goods Industries Association and others.
Leather is animal skin; getting wet does not in itself destroy it. The issues are how it dries and its oils. Handled properly, it usually recovers.
A patch that dries on its own leaves a rain-mark edge. Dampen the whole bag lightly, then dry it evenly — the method the leather industry also describes.
Sudden heat hardens, shrinks and cracks leather. Air-dry for 1–2 days.
Fluorine-based leather sprays are designed to repel water while letting the leather breathe. Silicone-based sprays can block breathability, so choose one labelled for leather and test it on a hidden spot first.
With waterproofing spray, a bag cover (or rain cover), and knowing what to do when it gets wet, it can be used every day. Switching to patent leather, synthetic leather or nylon on rainy days is another habit shared among people living in Japan.
