Do Gaijin Houses have laundry machines?

Most guest houses have laundry machines. They are usually coin operated. This can range from 100 yen to 300+ yen. In Japan it is rare for people to use a Dryer. Most people hang there laundry either in their room or on a balcony. Yes their underwear too! Coin operated dryers can become VERY expensive ranging at about 100-300 yen for 15 minutes, and usually take over an hour to dry your clothes.

You will also need to purchase your own laundry detergent, softener, etc.
