A while ago I said I'd cover bathrooms. Well, here it is. First the bath.

We have a gas water heater. To turn it on you have to turn on the gas flow (the little black knob of the far left), light the pilot (the big white knob on the left to 1) and once the pilot is lit you have two choices. Turning the knob to 2 causes the water coming from the shower head or the faucet to be hot. Turning the knob to 3 reheats the water in the tub. It's common to leave bathwater standing for a few days with the cover on it reheating as needed. As a further bonus this water heater also heats the water in the kitchen sink.

If you've never used gas you may not be familiar with the trickeries of pilot lights. They don't like to stay lit, particularly when it's cold. They're also really hard to see. Much swearing goes on while crouched, shivering, holding a towel over my head to block the sun and trying to light the pilot for the twentieth time. It can take upwards of five minutes on its very stubborn days.

Ok, now the toilet. By Japanese standards we have a very plain toilet. For the goods on the fancy ones you should check out this
article. The seat and all are pretty standard fare. Up top though, things are a bit odd. The two things you should notice are the flushing mechanism and the sink. The flushing mechanism can be turned in one of two directions. Your options are 大-dai (big) and 小-shou (small). They refer to the size of the flush and their purpose should be obvious. If you ever intend to come to Japan I
highly recommend you remember this to save yourself a few moments of uncomfortable confusion.

The faucet is actually a pretty cool idea. The clean water which refills the cistern is routed through a faucet and sink so you can wash your hands. Much better than hooking up an independent sink. As you've noticed the toilet and bathing areas are in different rooms. This makes perfect sense as only a filthy animal would bathe itself in the same place that it defecates. Oh, wait...
