One of my favorites has to be:

物理

Pronounced "butsuri." It means Physics. The characters roughly translate to principle of objects, which is why I like it. The word "Physics" in English comes from Greek, if I'm not mistaken, which makes it harder to know the meaning of the word without looking up its root. For Japanese, the meaning is right in front of you!

I also like it because I have a huge interest in Physics.
