"Deaths allegedly caused by the use of "choke holds" (shime-waza).
As I explained at the time, the 2 papers by Koiwai are cited a lot in this context, but it is also a unofrtunate as the stuff is very misleading because what he looked at weren't at all actual judo shime-waza but all sorts of movements that included neckcranks in several cases even using a police baton. As such, the information is almost irrelevant for judo chokes, as the lever forces and use of a hard object produces all sorts of additional injuries. So it is, for example, also no surprise that one finds fractures of the hyoid bone, etc. In some of his cases the victim is also held down by multiple people.
I was the guest-editor-in-chief in 1992 to produce a volume on judo injuries and myself and Koiwai corresponded about him producing a paper with actual relevant cases but it never transpired. The USJI Medical Committee of which he was the Chair then invited me several times to their meetings but they had the annoying tendency of faxing me an invitation about 2 days before the meeting took place, which given the fact that I was based in Europe at the time, was completely unrealistic. Nevertheless, they did not seem to understand that. There wasn't Internet and cheap travel agencies in those days and having to buy an intercontinental plane ticket just 2 days before the trip cost a small fortune, which would have to come out of my own pocket. Organizing an international trip just 2 days before leaving wasn't common either. There was not Google Earth, nor easy ways to figure out what close hotels were, which airport to fly into, and even international phone calls cost a ton of money then. Maybe the difference was that given that Koiwai owned his own horse racing stables and was working for one of the top-paying US universities, in addition to his private practice, we were in different social layers apparently where things that might be realistic for him were totally unrealistic for me and for most ordinary people. To put it simple, I was the one who wasn't the millionaire, which he did not seem to get.
