The Complete Guide to Japanese Coin Laundries and 3 Hidden Manners

🇯🇵 Japan Travel & Life Hack: 100% Utilization of Coin Laundry

If you travel or live in Japan for an extended period, you'll likely use a Coin Laundry (Koin Randorī) more often than you expect. It's incredibly convenient for large loads or drying, but it has some distinct characteristics and manners that differ from self-service laundromats in other countries. Here is my complete guide to using a Japanese coin laundry and three easy-to-miss etiquette tips.

💡 Key Features of Japanese Coin Laundries

1. Washer-Dryer Combos are Dominant

Many modern Japanese coin laundries feature large machines that can complete both washing and drying in one go. You put your clothes in, select a course, and the machine handles the rest.
Automatic Detergent Injection: Most systems automatically inject detergent and softener, so you usually don't need to bring your own. (Some older locations still have slots for personal detergent, though.)

2. Accepts Paper Bills:

While other countries rely on coins or cards, many Japanese coin laundries require you to insert a 1000 yen bill directly into the machine or use a change machine to get coins. Make sure to carry smaller bills or coins with you.

📌 4 Steps for Perfect Coin Laundry Use

Sort and Check Weight: Divide your laundry by weight and load capacity. Overfilling the machine can lead to poor washing results.
Machine Sanitization (Optional): If you are conscious about hygiene, you can press the '槽洗浄 (Tub Cleaning)' button or run a quick hot water cycle before loading your clothes.
Select Course and Pay: Most machines offer Standard (標準), Powerful (強力), and specialized courses like Futon (布団). Select your desired course and insert the fee.
Drying: Drying time is crucial. Too short, and the clothes will be damp; too long, and they might shrink. 30–40 minutes is a good starting point, and I recommend checking thick items mid-cycle and adding time if necessary.

🤫 3 Easy-to-Miss Japanese Coin Laundry Manners

1. Be Punctual:

Once your wash or dry cycle is finished, you must promptly remove and fold your laundry for the next person. Be mindful of your time, as someone may be waiting for the machine.

2. Respect Other People's Laundry:

If the previous person's cycle is done and they haven't returned, the basic etiquette is not to touch their laundry. If you are in a rush, politely place it on a clean basket or table, but never move it onto the floor or rush the process.

3. No Pet Items:

Washing pet items (blankets, clothes, etc.) is strictly prohibited in most coin laundries due to allergy and hygiene concerns. Always check the posted rules to avoid trouble.

By observing these manners, you'll ensure a pleasant and efficient coin laundry experience in Japan!
