Although almost everyone in Tokyo has a washing machine, very few people seem to have dryers. Laundry is usually hung outside to dry.
In apartment buildings, that means hanging your undies out on the balcony and draping futons over the railing or out windows. Sunny days look a little bit like a bazaar with clothes flapping in the high rise breezes. Several buildings in our neighborhood have communal space for laundry on the roof--they're completely caged in to keep things from blowing into the streets below.
I have a dryer but I still like to dry things outside. I'm amazed at how quickly towels dry in the sun. Half the time of doing them in the dryer. Sheets are dry in 30 minutes on a breezy day. And despite the polluted Tokyo air, things dried outside smell fresh.
Hanging my laundry is like therpy to me. It gives my great comfort to see my laundry blowing in the breeze!!
Smell fresh - except in the months of June, July and most of winter...washing can be a pain when you don't have a dryer...
I LOVE sundrying sheets and towels especially. Nothing better than that fresh smell getting into bed at night. :- )
I miss my gas dryer that I left in my home in Bunkyo. Sun drying is not bad, though, here in Kyushu as long as it dosen't rain like today.
