Why Custom Keychains Are the Hottest Merch Item in Japan & Korea

In Japan and Korea, small accessories are big business. From anime conventions in Akihabara to K-pop fan clubs in Seoul, soft PVC keychains have become the default merch item — and the trend is spreading to Western collectors. Here is why, and how to ride it.

The culture of "small goods" (kogoods)

In Japanese fan culture, kogoods — small merchandise like keychains, badges, and acrylic stands — are a multi-billion-yen category. Fans buy them to decorate bags, desks, and phones. PVC charms are the favorite format because they are soft, collectible, and can be produced with incredible detail.

K-pop and the "official merch" economy

Korean entertainment companies sell official character merch — keychains, dolls, and photocards — to highly engaged fan bases. Official keychains sell out in presales, and the same manufacturing know-how serves brands that want original, non-licensed characters inspired by this aesthetic.

Why PVC wins in this market

• Detail: complex hair, outfits, and expressions can be sculpted into 3D PVC.

• Cuteness: soft-touch material and rounded shapes match the kawaii aesthetic perfectly.

• Collectibility: fans collect series — different colors, poses, and limited editions.

• Giftability: small, light, and affordable — ideal for gifting between fans.

How to enter this market responsibly

Create your own original characters instead of copying licensed anime or idol imagery — this avoids copyright issues and lets you build a brand fans can genuinely own. Original mascot series, seasonal variations, and fan-club exclusive runs are proven strategies for both the Japanese and Korean markets.
