The Cash Tray: How to Use It at Japanese Registers

Most Japanese cash registers have a small tray for cash. You put money in the tray, not the clerk's hand. Skip it and you disrupt the rhythm.

Extending your bills and coins directly across the counter, hand to hand

When you try to hand cash directly to a Japanese clerk, you can create a small moment of confusion. Where there's a tray, many clerks expect the money to go in it rather than into their hand. They'll often gesture at the tray silently, or accept the cash and then place it in the tray themselves. Either way, you've introduced a small hitch into a transaction that was supposed to be frictionless.

Place the cash neatly in the tray, bills flat, coins on top

Look for the small tray on the counter, usually right by the register. Place your bills flat in the tray (folded bills go flat, not creased), coins on top of the bills or in a small pile, and slide the tray slightly toward the clerk. They take the tray, count the money, and usually put the change and receipt back in the tray for you to retrieve.

Grabbing coins and bills out of the clerk's hand for change

Holding your palm out and waiting for the clerk to drop coins into it

Same problem in reverse. When the clerk gives you change, they often place it in the tray rather than in your hand. Holding your palm out expecting them to drop coins into it creates the same confusion: they're aiming for the tray, you're aiming for a hand-off, and the coins end up in a weird half-exchange.

Wait for the change to land in the tray, then pick it up

The clerk will usually set your change, receipt, and any small items (like a handful of loyalty points coupons) in the tray. Wait for them to finish, then pick everything up from the tray yourself. If they also hand you a shopping bag, that comes directly—but at a register with a tray, the money part of the exchange usually goes through it.

Registers where you pay into a cash machine yourself

Holding out your cash or using the tray when the clerk points you to the machine

Some convenience stores and supermarkets use registers where the clerk scans your items, but you pay at a cash machine beside the register. 7-Eleven, for example, began introducing this kind of register in 2020. If the clerk gestures toward the machine and you hold your bills out to them or put them in the tray anyway, the clerk has to stop and redirect you, and the line behind you waits.

After the scan, if you're pointed to the machine, put the cash in yourself

Let the clerk scan your items first. If they point you to the machine next to the register, feed your bills and coins into it yourself. The machine counts the money, and your change comes out of the machine, not from the clerk. Pick it up there, and you're done.

Overthinking the tray and causing friction

Hesitating, asking 'tray?' and looking confused while the clerk waits

Sometimes tourists who've read about the tray rule overthink it at the register. They freeze, look around, try to ask if they should use the tray, and make a bigger deal of it than necessary. The tray is obvious when you see it—a small, shallow tray right in front of you. Clerks deal with both 'tray users' and 'direct handers', and will usually just carry on with whatever you do.

Just put the cash in the tray with zero ceremony. No words needed

This isn't a test. Put the money in the tray, wait for the change, take the receipt, say 'arigatou gozaimasu,' leave. The whole interaction is mechanical. The tray rule is a small lubricant for the machine, not a formal ritual you have to perform correctly.

Why a little tray runs cash transactions

The money tray—called karuton (カルトン, from the French carton) or simply a change tray—sits on most Japanese cash registers for two main reasons: avoiding hand-to-hand contact and keeping coins under control. It keeps a little distance between clerk and customer, and with six denominations of coins in circulation, laying everything out on one surface keeps coins from scattering and lets the clerk check the amount at a glance.

The system predates the pandemic by decades—trays like this spread to banks and shops in the early Showa era. COVID just gave it a fresh boost.

Where there’s a tray, cash goes in the tray. Where the clerk points to a machine, cash goes in the machine. That’s the whole rule.

A few “nice to know” extras

  • Paying by card — Credit cards are usually handed to the clerk, or inserted or tapped at a terminal on the counter. Some terminals can switch to English.
  • IC cards and QR payments bypass everything — Tap your Suica or scan PayPay and the tray simply sits there empty.
  • Coin counting takes a beat — If you dump a fistful of 1-yen and 5-yen coins into the tray, the clerk will count them carefully. Don’t hover. Let the count finish, then the transaction moves on.
  • The tray doubles as an object handoff — Receipts, coupons and other small items sometimes come back in the tray alongside your change. Scoop it all up together.
