When the rainy season or typhoon season rolls around, there’s nothing worse than showing up to class or the office completely soaked—it can make the whole day uncomfortable. That’s why having reliable and practical rain gear is more important than ever!

In this post, we’ve rounded up some popular and useful rain essentials—from raincoats and waterproof shoe covers to stylish Japanese outerwear. We’ve also included some handy tips on what to look for when choosing your rain gear!

Water-Repellent (撥水) vs. Waterproof (防水): What’s the Difference?

When shopping for rain gear, you’ll often see labels like “water-repellent” and “waterproof”—but what exactly do they mean? Don’t get them mixed up! Picking the wrong one could leave you soaking wet.

Water-Repellent: Lets Water Roll Off the Surface

Water-repellent treatment is applied to the surface of the fabric, allowing water droplets to slide off—much like how rain rolls off a lotus leaf. However, since the fabric still has tiny gaps, water may seep through the seams or after prolonged exposure to rain. Plus, the water-repellent effect can gradually wear off after repeated use or washing.

Waterproof: Completely Blocks Out Moisture

Waterproof designs usually involve adding a waterproof membrane to the inner layer of the fabric or applying a special waterproof coating. This helps prevent water from seeping in through the surface or seams, making it ideal for extended exposure to rain or situations that require strong protection. However, damage to the fabric or long-term use may reduce its effectiveness, so hand washing and gentle care are recommended.
