Smart Ways to Use Japanese Coins
A Practical Guide to Spending 1-Yen to 500-Yen Coins Before Leaving Japan
Hello, this is Kori.
If you’ve ever traveled to Japan, there’s a moment you’ll probably recognize instantly.
On the first day of your trip, you buy a drink at a convenience store and hand over a ¥1000 bill. The cashier smiles politely and returns a handful of shiny coins. The sound of them jingling in your wallet feels oddly satisfying.
But by day two or three, that pleasant sound turns into something else.
Your pockets start sounding like maracas every time you walk. At checkout counters, you find yourself digging frantically through coins before eventually giving up and handing over another bill — which only makes the problem worse.
Then, on the flight home, you discover a pocket full of ¥1, ¥5, and ¥10 coins and promise yourself:
“Next time, I’ll definitely spend all of these before leaving.”
So today, let’s solve that problem once and for all.
Here are some practical, real-life tricks to spend Japanese coins efficiently and lighten your wallet before your trip ends.
Understanding Japan’s Coin Culture
Japan still has a relatively strong cash culture, even though contactless payments have grown quickly in recent years.
Small restaurants, local shops, and shrines often prefer or require cash. Because of that, travelers inevitably accumulate coins.
Before trying to spend them wisely, it helps to understand how each coin is commonly used.
| Coin | Material / 특징 | Practical Use |
|---|---|---|
| ¥1 | Aluminum (extremely light) | Cannot be used in machines; useful for exact change |
| ¥5 | Brass with center hole | Often used as shrine offerings |
| ¥10 | Copper | Minimum coin accepted in most machines |
| ¥50 | Nickel with center hole | Used in vending machines and coin lockers |
| ¥100 | Nickel | Most commonly used coin in Japan |
| ¥500 | Nickel-brass | High value coin, useful for meals and shopping |
One key thing to remember:
¥1 and ¥5 coins usually cannot be used in machines.
1. Use Convenience Store Self-Checkout Machines
The fastest way to get rid of coins is surprisingly simple.
Convenience stores.
Major chains like
- 7-Eleven
- Lawson
- FamilyMart
often use automated payment machines.
Here’s how it works:
- Scan your items
- Choose “cash”
- Pour your coins into the machine
Yes — literally dump them in.
The machine counts everything automatically, including small coins like ¥1 and ¥5.
This makes it the easiest place to empty a heavy wallet without holding up the line.
Large supermarkets like Don Quijote or LIFE also have similar machines.
2. Recharge Your Suica or Pasmo Card
One of the smartest tricks during a Japan trip is converting coins into transport credit.
Japan’s IC cards such as:
- Suica
- Pasmo
- Icoca
can be recharged at train station machines.
Most machines accept:
- ¥10
- ¥50
- ¥100
- ¥500
So if you have a pile of coins, simply:
- Insert your IC card
- Choose “Charge”
- Feed the coins into the machine
Your loose change instantly becomes digital travel credit.
You can later spend that credit on:
- trains
- vending machines
- convenience stores
- airport shops
Just remember:
¥1 and ¥5 coins cannot be used in recharge machines.
3. Use Mixed Payment at Airport Shops
If you still have coins at the airport, don’t panic.
Japan’s stores are very flexible with split payments.
You can simply say:
“Use the coins first, and I’ll pay the rest by card.”
The cashier will count your coins and deduct them from the total.
Then the remaining balance can be paid with:
- credit card
- travel card
- digital payment
This is one of the best ways to eliminate every last coin before leaving Japan.
4. Turn Coins Into Travel Fun
Instead of stressing about coins, you can also turn them into small travel experiences.
Capsule Toys (Gachapon)
Many machines cost:
- ¥100
- ¥200
- ¥500
Perfect for spending coins while collecting fun souvenirs.
Shrine Offerings
In Japan, the ¥5 coin has a special meaning.
It’s pronounced “go-en,” which sounds like the word for good fortune or good relationships.
Because of this, many visitors place a ¥5 coin into shrine offering boxes when making a wish.
Pocket Change Exchange Machines
Some airports and malls have machines called Pocket Change.
They convert leftover foreign coins into:
- e-money
- gift cards
- digital credits
The fee can be slightly high, but it’s still useful if you have many coins left before departure.
A Hidden Rule You Should Know
Japan has a legal rule regarding coins.
You cannot use more than 20 coins of the same denomination in a single transaction.
For example:
Trying to pay ¥210 using 21 ¥10 coins can legally be refused.
Some machines will even reject excess coins.
So the best strategy is simply to use coins gradually during your trip.
Kori’s Thoughts
Japanese coins might feel annoying at first.
But once you understand how they work, they actually become a fun little puzzle during your trip.
Using the exact coins for a perfect total — down to the last yen — is strangely satisfying.
Next time you travel to Japan, try combining these three tricks:
- convenience store self-checkout
- Suica recharge
- airport mixed payment
With these, your wallet will be lighter and your trip will end on a neat, satisfying note.

Most banks outside Japan do not accept foreign coins. Even if they do, the exchange rate is usually extremely poor. It’s generally best to spend all coins while still in Japan.
Q2. Can ¥1 or ¥5 coins be used in vending machines?
No. Most vending machines and ticket machines only accept coins starting from ¥10.
Q3. What happens if I insert too many coins into a self-checkout machine?
Japanese law allows only up to 20 coins of the same denomination per transaction. If you exceed that number, machines may reject the extra coins.
