toilet in Japan

You remember I told you before that the toilet in Japan are quite special.
And here some more proof!
In case you don't know what to do, here some visual explanation.
This was good because I was on my way to use them wrong :-)

the first one was maybe easy but then, ohhh my god somebody help!!
And if you press the wrong button there will be an alarm, yes yes, and this is always happening to foreigner!!!
You see the red button, very often you think this is to flush, but no no no!!!

And then that's not over, button to wash in front, on the back, to make music, for the temperature of water, the pression and I don't know what.
You can just spend hours in the toilet just trying everything.
Greaaat:-)
