On my old hakama, soon to be retired, I have my last name, but somewhat phonetically done in kanji. It reads "shin bu son" for "Simpson", but the kanji translates roughly to "grandson of true warrior" and was done to remember my Grandfather who I never got the chance to meet. My belt is blank.
I find names on gi's helpful, rather than egotistical. It's very helpful at a big seminar too, kind of like name tags at a party. Although I don't have my name on mine, my wife is threating to write it on the inside of the collar, like at camp, if I leave it around the gym again.
