Mainichi is a wonderful thing, as this passage demonstrates:

Take the Shigurechausu, or time of thin rain and tea. This is a position where the woman gets on top. If the woman shifts to her side while riding atop the man, the position turns into the goshoguruma, or ox-drawn cart like those used by ancient royalty. If you’re both looking in the same direction while being sideways, that is, insertion from the rear while both are lying side-on, it’s called the mado no tsuki, or moon window. Turning the woman in the opposite direction gives you the Tsubame Kaeshi, or inverted swallow (as in the bird)…

I wonder if they’re hiring translators. It might be worth dropping out of law school.
