    If rainfall continues for several days and you don’t have a drying machine at home, coin laundry should be your answer. Recently, coin laundries in Japan have become more comfortable and sometimes they even have a cafe and free Wi-Fi service included, so you can sip a coffee, read some books, or do some work while waiting for the laundry to finish. Some might have “a sneaker laundry” so you can easily wash your shoes as well.

    What to bring

    Detergent and softener are added automatically for most types of washing machines, but it might be better to bring your favorite ones if you are particular about it. It’s also better to bring a washing bag to prevent dryer damage. (You can find one in the 100 yen store.)

    Obviously, you need some 100yen coins as well. Some places might have a money changer but it’s better to bring several 100yen coins if possible, just to be sure you have some change.

    It takes about 30 minutes to finish one laundry and usually costs 400 yen to 700 yen. If you use a drying machine, it costs about 100 yen for 10 minutes.

    Dehumidifiers with clothes drying function

    Dehumidifiers are by no means cheap, and some of them can make your electricity bill skyrocket, so it’s important to do your research before buying one. Essentially, there are three types of humidifiers in Japan. Ones are meant for winter since they make rooms hotter and because they target condensation, others are meant for summer since they make temperatures stay almost the same, and others are called “hybrid” because they have both functions and can be used year-round.

    A/C units also have a dehumidifying option, but depending on where you live it might not be enough. The great thing about dehumidifiers is that they also come with a clothes-drying function.

    So, knowing all of these, there is no need to put of doing your laundry!
