Collecting eki stamps with kids: Japan’s free station-stamp game

Here is the best free activity in Japan you’ve probably never heard of: eki stamps. An eki stamp (駅スタンプ, “station stamp”) is a rubber stamp kept at the station itself, each one a unique design showing a local landmark, mascot or the station’s own character. They’re completely free, they’re at most Tokyo Metro stations and many JR and Toei ones too, and for a child they turn an ordinary day of trains into a running treasure hunt — with a hand-stamped souvenir to take home.

We think it’s one of the single best things you can do with kids in Japan on a budget. Here’s how to make the most of it.

Why it’s brilliant with children

• It’s free, and it’s everywhere you’re already going — no tickets, no detours.
• It turns transit into a game: kids who’d normally groan at “one more train” start asking to stop at the next station.
• It’s a real, personal souvenir — a book of stamps from exactly the places your family went, worth far more than a fridge magnet.
• It quietly teaches map-reading, patience and a sense of place, and works for a wide age range — from a toddler pressing with help to a teen curating their own book.

What to bring

Almost nothing — that’s the beauty of it. A small blank notebook does the job; unlined or plain paper shows the designs best. If you want to make it special, stationery shops and some station stores sell dedicated stamp notebooks (a “stamp book”), and giving each child their own turns it into a personal keepsake and heads off squabbles. That’s it: the ink pads live with the stamps.

Where to find the stamp

Most eki stamps sit just outside the ticket gates, on a little stand or counter, or at the station office / staff window. Occasionally one is inside the gates or kept behind the counter, so if you can’t see it, ask a staff member — “Eki stamp wa doko desu ka?” (where is the station stamp?) works, and staff are used to the question. A few stations don’t have one, so treat each find as part of the hunt rather than a guarantee.

Simple tricks that make it work

• Do a test press on a scrap page first — inking varies, and a quick practice avoids a smudged keepsake.
• Press straight down firmly and lift cleanly; don’t rock the stamp.
• Give it a moment to dry before closing the book, or slip a scrap of paper over fresh ones.
• Date each stamp and jot the station name — future-you will love the little travel diary it becomes.
• Keep the book in a zip-lock bag so it survives bags, rain and juice cups.
• Be quick and tidy at busy gates — it’s self-serve, so stamp and step aside so you’re not blocking commuters.

Good to know

The stamps are a long-running tradition and the networks refresh them from time to time — JR East, for instance, has rolled out renewed stamp designs — so the exact artwork can change between visits. Alongside the classic physical stamps, railways occasionally run limited-time “stamp rallies” (collect stamps at a set of stations for a small prize) and some digital, app-based versions; the everyday, free, ink-and-paper stamps at the stations are the ones to build your family hunt around. However you do it, a stamp book is the cheapest, most personal souvenir your kids will bring home — and a lovely record of every station your trip ran through.
