This is a very strange way of remembering this Kanji, but I thought I would share it with others. When I was in high school my Japanese language teacher would always try to come up with really crazy and weird ways of remembering Kanji characters, this one stuck with me. So for "¤Ð¤ó" which means evening and night, she suggested we think of it as after the day ("¤Ò" radical) you can eat your fish ("¥¯" looks like a fish) from your obentoo box on the table (bottom part looks like table legs). Well, that last bit might be a stretch, but otherwise it works and I definitely have not forgotten this Kanji.
