👘 Japan’s Seasonal Wardrobe Switch: The Culture of Koromogae

As Japan transitions from spring to the humid rainy season, many households begin preparing for koromogae — a traditional custom of switching wardrobes based on the seasons.

If you’ve never heard of this practice, don’t worry. In this post, we’ll walk you through the background of koromogae, why it’s still widely practiced today, and what it says about Japanese culture.

🌿 What Is Koromogae?

Koromogae (衣替え) literally means “changing clothes.” In Japan, this refers to the seasonal switch of clothing — not just what you wear each day, but your entire wardrobe.

Typically:

・Summer clothes come out in June

・Winter clothes come back in October

This isn’t just a personal preference — even schools, government offices, and companies used to have official dates for switching uniforms. The tradition is still alive, especially among families and schools.

🏯 A Tradition Rooted in History

The origins of koromogae date back to the Heian period (794–1185), when nobles would change the color and material of their clothing to match the season.

Later, during the Meiji period, this practice became systematized — public servants and students were instructed to change uniforms on set dates (June 1 and October 1), a system that still influences modern customs.

☔ Why It Matters Before the Rainy Season

Japan's rainy season (tsuyu) begins in June. With the rise in humidity, it's important to store away winter clothes properly to prevent mold, odor, or damage.

That’s why koromogae is not just about fashion — it’s a seasonal ritual of refreshing your living space.

Typical steps include:

・Washing or dry-cleaning winter clothes

・Adding dehumidifiers or natural moisture-absorbing items like charcoal or washi paper

・Folding items in breathable cloth bags (some use furoshiki – traditional wrapping cloth)

🧺 More Than Just Cleaning — It’s Cultural

For many Japanese people, koromogae is also a time to reflect and reset. The idea of “living in harmony with the seasons” (kisetsu o tanoshimu) is deeply rooted in daily life — from food and fashion to home decor.

Even today, Japanese homes are often designed with seasonal living in mind: sliding doors, breathable materials, and flexible storage that make wardrobe changes feel natural.

🎐 Try It Yourself!

While Japan has four distinct seasons, the idea of rotating your wardrobe — and mentally preparing for a new season — can be meaningful no matter where you live.

Next time you feel a seasonal shift, consider:

・Refreshing your closet

・Letting go of what you no longer need

・Adding small seasonal touches to your home or routine

You may find that this simple practice brings a surprising sense of renewal.
