Humidity and cleaning the bathroom

Japan is a very humid country, especially in the summer. If you're in central Japan, for example Tokyo, in July-August, don't expect to be able to walk more than 10 meters without being soaked in sweat. Japanese people call this 蒸し暑い (mushi-atsui), pretty much meaning humid and hot.
That was a big reason for me to go to Sapporo, on Hokkaido in the north of Japan. The climate is quite a bit cooler and a lot less humid here, also it's always windy which is nice in the summer, but not so nice in the winter.
However compared to Sweden, even Sapporo is a lot more humid, which has some consequences.

• Everything here in Japan is packed in lots of plastics. If you buy a pack of cookies, of course it comes in a plastic bag like anywhere in the world, but here, each cookie is in a small plastic bag of it's own also, or there's one of those small bags included that absorbs moisture, that only comes in shoe boxes in Sweden. Partly because of the humidity but also because Japanese people are obsessed with having all food very fresh.
  It becomes a lot of plastics, I am telling you. Just too bad that you can only throw away plastics once per week here in Japan. All refuse is sorted into burnables, non-burnable and plastics and has specific days when you're allowed to throw it. So you need to keep your garbage in your apartment until the day when it's supposed to be thrown.
  

• Here in Sapporo, the laundry might be dry after about 24 hours if you're lucky. Sometimes 24 hours is not enough. I wonder if it's possible at all to get your laundry dry in southern Japan in the summer?

• There's always some funny pink stuff growing on the floor in our bathroom. The Japanese bathrooms are entirely made of plastic and has a bath tub and a shower next to it. Japanese people love taking a bath, but showering in the bath tub is not okay. Anyway, the floor's surface in our bath room is not even, which is good since a perfectly flat plastic surface would be a lot more slippery. However, the cute little pink colored stuff loves the small bumps in the floor, combined with the humidity and no window in the bathroom, it's obviously very good conditions to grow quickly, and it's an absolute pain in the ass to get rid of. We have some kind of bathroom cleaner, on the bottle it says you're supposed to just spray it on, wait a few minutes and wash with water and you're bathroom is clean (not that I can read it at all, but my girlfriend says so). Hah! More than one hour of rubbing the floor like a maniac with a sponge is what it takes to get rid of the pink bastards. And within a week they'll be back again...
