Re: Kanji in my Gi (need your help and opinion)
I would suggest that it is from a school, the Izumi being a district and the Kita being the school (e.g. Izumi Kita High School)
I would not be surprised if it is in fact a judogi from a school club.
My take: you might remove the emboidery with an un-picker (a lot of time), or put a patch over it. That, of course, is merely my opinion.
Hope this helps.
