How and why in the H - E - double hockey sticks do you know that? :o)
My screen name (chajin=person who studies Japanese tea ceremony) should give it away :-) OK, it's a bit more complicated than that.
There is another word for "dawn" in Japanese, akebono 曙, with the sun kanji on the left, and on the right the sun at the bottom ready to rise above the horizon of the earth, with the moon (written sideways) still in the sky.
I know this one for two reasons. One is that there is a particular type of lacquering by that name, which is dark with faint red streaks, like the first light of the dawn, one of the many types of lacquering used in tea containers.
The other reason is that Akebono was the "ring name" of the first Hawaiian to achieve the top sumo rank of yokozuna, in the 1990s, though he was broke when he retired from the ring, and has become of all things a professional wrestler, a living example of the tragic movie Requiem for a Heavyweight.
