Why Are Japanese Cashiers So Good at Tetris? (The Supermarket Masterclass)

The Art of the Basket

When a Japanese cashier scans your items, they don’t just throw them into a bag. If you use a supermarket basket, they meticulously transfer the scanned items into a second, different-colored basket. Heavy items like milk go perfectly at the bottom, while fragile eggs and soft bread are gently placed on top.

The Eco-Bag Magic

Many shoppers in Japan now bring a “My Basket” or a large eco-bag that fits perfectly inside the store’s shopping basket. When you hand this to the cashier, they will pack your groceries directly into your bag with astonishing speed and architectural precision.

The Bagging Desk (Sakka-dai)

If they don’t bag it for you, they hand you the perfectly organized basket to take to a dedicated packing table called the “Sakka-dai.” Here, you can take your time packing your own bags without the pressure of the next customer glaring at you from the line.
