(ant)
I've always liked ants, because they are one of the strongest animals in the world based on their size. I love how the kanji means "righteous insect" and refers to how ants work together - somehow it seems like a very Japanese way to describe the insect. I also love this kanji because when I began studying Japanese, I listened to a Japanese band called Ali (蟻) Project and learned a lot from their music. So, this one has got to be my favorite!
