As I mentioned on another thread, I find it remarkable the focus on IT/IP/IS is mainly concentrated in/on the US.
In fact, no European resident is noted on that list, or African, Russian, South American etc. for that matter.
... Checking out German and French martial arts forums might be good idea.
IT/IP/IS is no issue in german martial arts forums. At least not in forums concerned with Japanese martial arts.
I learned the vocbulary here on aikiweb. An I don't know whether there are teachers over here in Europe, teaching something, you would call IS or IP.
