Re: Kanji in my Gi (need your help and opinion)
It's pretty common in Japan for people to wear gi that have either their own name or the name of the club/dojo where they train. Since 泉北
is a place name it might also be the name of a dojo/club/or organization. I have also seen people wear gi and hakama that have the kanji for a name other than their own; probably bought 2nd hand I would assume.
