Yonder, Facing
A drop hits your mustache. Where did it come from? "Ah, it came from yonder," you say, facing that way.
Yonder is a bit of a weird word, but it fits the meaning of this kanji quite well. You'll have to trust me that it's more useful in Japanese than it is in English. When you imagine through this mnemonic, make sure the drop comes from the side and hits you in the mustache with quite a bit of force. That means it came from a far distance thus making you look over "yonder."
こう
む
なた
Who shot this drop at you from yonder? You look over yonder, and see a figure. It is こういち.
"Who is that over yonder!" you yell. "It is I, (こういち)," he yells back. "I shot at you over yonder because you weren't doing your kanji reviews often enough and you're taking up space on our database." "But I'm paying you!" "Oh, that's true. Well, I'm going to walk over yonder and leave you alone, then."
