がま口 (Gamaguchi) — The Wallet with a Big Mouth and Even Bigger Personality 👛
Share
If you’ve ever used a がま口 (gamaguchi), you know the feeling.
Click. Open wide.
Clack. Shut tight.
It’s dramatic. It’s satisfying. And it’s been part of everyday Japanese life for over a century.
👛 What Is a がま口?
A gamaguchi is a clasp-style pouch or wallet with a rounded metal frame that snaps open and closed. The name literally means “frog mouth” — because when it opens, it looks like a frog about to croak.
Once you see it, you can’t unsee it.

🕰 A Practical Idea That Stuck
Gamaguchi became popular in Japan in the early 1900s, when Western-style coin purses were introduced. Japan adopted the mechanism — then made it better.
Why it worked:
- Opens wide so you can see everything
- Closes securely with a firm snap
- Durable, repairable, and long-lasting
Simple mechanics. Smart design.
💰 The Wallet That Eats Everything
Coins, bills, receipts, charms, secrets — gamaguchi doesn’t judge.
You drop things in, and it just accepts them.
Open mouth. No questions.
That’s part of the charm: it feels almost alive, like it’s always ready to eat just one more thing.
🎒 From Coin Purse to Everyday Icon
Today, gamaguchi come in all forms:
- Tiny coin pouches
- Long wallets
- Bags
- Cases for glasses, makeup, or tools
You’ll find them in traditional fabrics, bold modern prints, and playful character designs. Old-school shape. Endless reinterpretation.
