How to Use a Japanese Washing Machine: A Translation Guide
Moving into your Japanese apartment is exciting—until you stare blankly at the washing machine, covered in kanji you can't read. Don't worry; you're not alone. This guide breaks down every common button, setting, and symbol you'll encounter so you can tackle laundry day without accidentally shrinking your favorite shirt.
Understanding the Basics
Most washing machines in Japanese apartments are top-loading units with a built-in spin dryer (not a full tumble dryer). Water flows in from a hose connected to your sink or wall tap, and drains through a hose into the floor drain.

Final Tips for Laundry in Japan

- Drying indoors: In humid seasons (梅雨/tsuyu), use a fan or dehumidifier to dry clothes faster
- Trash your lint: Don't forget to clean the filter regularly!
