My UK blood could never never grow accustomed to the bright Japanese sun, so sunglasses are a must for me, but be sure to take them off when ever you are on school grounds and whenever talking to someone face to face. I will say that it was hard for Japanese people to understand that I didn't wear sunglasses to look cool, but to be able to see without squinting all day. If you don't need them, though, I wouldn't bring them, like Nyororin said.
