The reel above, published 28 September 2026, puts unlabeled grapes on the belt. The register cannot scan a bag with no barcode. The question that finds the weighing is 計量はどこですか? This page is that question, the sticker a scale prints, and the packs that skip it.
What does 計量はどこですか mean at a Japanese supermarket?
計量はどこですか? (keiryō wa doko desu ka) means "Where do I weigh this?" 計量 (keiryō) is weighing. The word is four beats, ke-i-ryo-o, and the romaji marks the long o. は (wa) marks weighing as the topic. You write it は and you say wa. どこ (doko) means where. です (desu) is the polite "is," and か (ka) makes the question. The polite full line puts すみません (sumimasen) in front: すみません、計量はどこですか? The すみません guide is that opener on its own. You are asking where the weighing happens. You are not asking the price, and you are not asking anyone to ring the grapes up yet.
What do you do at the scale once you find it?
Bag the loose fruit, set the bag on the scale, press the icon that matches what is in the bag, and stick the printed barcode on the bag. Then the register can scan it. Teraoka Seiko's patent JP7176740B2, filed 11 January 2019 and granted 22 November 2022, describes two ways a supermarket produce aisle handles that pile. Loose vegetables and fruit sit with no price and no barcode. In one way, you bag them, and the cashier weighs the bag at the register and presses the key for that item. The other way uses a machine beside the piles. You bag the produce, set it on the scale, pick the icon on the touch panel, and the scale prints a barcode label. You stick that label on the bag before you join the line. Teraoka's SM-6000 product page, checked 1 October 2026, is a self-service scale for the case where the customer does the weighing and the price labeling. The page says the scale can subtract the container's weight, and a paper bag is one of the containers it lists. If the clerk says they will weigh the bag here, hand it over and stay. A pack that already shows a barcode skips the machine. The bag in this step is the produce bag. It is not the shopping bag the cashier offers when you pay.
Which produce needs a sticker, and which already has one?
Loose produce with no barcode needs a printed sticker, or a cashier to weigh the bag. A tray, a net, or a bag that already shows a barcode goes straight to the line. The same apple can sit both ways in one aisle. One pile is loose. The next shelf is a four-pack with a label already on it. Read the price card before you print anything. A price per 100 grams, written 100gあたり (hyaku guramu atari), means the sticker price comes from the weight. A price per piece, 1個 (ikko), can still need a printed barcode when nothing is stuck on the fruit, because the register reads barcodes, not the pile. If a sticker is already on the pack, do not print a second one. A second sticker can make the scanner read the wrong code. Pre-packed meat, fish, and side dishes almost always carry a staff label from the back room. Leave those labels alone. The scale on this page is for the unlabeled pile.
How is 計量 different from はかり and 量り売り?
計量 (keiryō) is the act of weighing, and it is the word in the question. はかり (hakari) is the scale itself, the machine. はかりはどこですか? (hakari wa doko desu ka) asks "where is the scale?" and staff understand it. The sign and the reel use 計量, so that is the line to learn. 量り売り (hakari-uri) means sold by weight. 量り comes from 量る (hakaru), to weigh. ばら売り (bara-uri) only means sold loose, not sealed in a fixed pack. Loose is not always by weight. Bananas sold by the bunch are ばら売り and may still be a count, not a weight. Use 計量はどこですか? when you need the place that prints the sticker or weighs the bag. Use これは量り売りですか? (kore wa hakari-uri desu ka) when you are asking whether the price depends on the weight.
What do you say if the cashier sends you back?
Say すみません、計量はどこですか? The bag has no barcode, so the scanner has nothing to read. In the reel, that is the grape bag, and the people behind you wait. A common answer is あちらで計量してください (achira de keiryō shite kudasai), "please weigh it over there." あちら (achira) is the polite "over there," and the clerk will usually point. してください (shite kudasai) is "please do." If the register can weigh it, you may hear こちらで計量します (kochira de keiryō shimasu), "we will weigh it here." こちら (kochira) is "here," on the staff side. Then you wait. You do not walk off to find a second machine. When you are handing the bag to a person, the other line is 計量お願いします (keiryō onegai shimasu), "please weigh this." お願いします (onegai shimasu) means "please." That line asks the person to do the weighing. どこですか asks where it is. Some shops never put a customer scale in the aisle. Staff label the produce, or the cashier enters the item. The question still works. It tells them the bag has no sticker, and they show you which path this shop uses.
What if you are scanning with a store phone instead of a scale?
That phone is a different machine, and 計量はどこですか? is the wrong question for it. Aeon Kyushu's notice of 10 February 2022, for the Regi-Go start at Aeon Saga Yamato on 17 February 2022, says you scan barcodes with a store phone or your own phone as you shop. Vegetables and fruit with no barcode are entered by scanning the shelf card's barcode, or by picking the item on the touch panel. No weighing sentence comes up in that notice. If a clerk handed you a phone at the door, stay with that phone and the shelf card. If nobody handed you a phone and the grapes have no sticker, you are on the scale path, and the question on this page is the one to use. Paying comes after either path. The card guide covers the register once the barcode exists. A convenience-store counter is a third place. Konbini fruit is almost always packed already, and those phrases live in the convenience-store guide.
The grapes need a barcode, or a cashier with a scale, before the belt can take them. 計量はどこですか? (keiryō wa doko desu ka) asks where that weighing is. Bag the loose fruit, press the matching icon, stick the label on, and then join the line. If they say they will weigh it here, hand over the bag. A pack that already has a barcode skips the scale.
