The Kodokan has numerous materials detailing the canonical versions of their shime-waza along with several variations. However, there are a large number of competition chokes (and novel chokes imported from BJJ) which are not covered. How are these classified?
Below is a list of chokes and how they fall into the 12 current Kodokan shime-waza classifications. Note that like with certain throws, there is often debate as to whether certain choke applications fall into one category or another (e.g. okuri-eri-jime vs kata-te-jime).
- Techniques denoted with an asterisk are not competition legal (* † ‡).
- Letter superscripts represent examples in competition ( a b c ).
- Number superscripts represent referenced materials ( 1 2 3 ).

1. Rolling entry sometimes referred to as kaiten-jime / oten-jime. Often misspelled "othen-jime", presumably from misreading "oh-ten" (大転, "big turn") as "o-then".
2. Ude-shibori seems to be just an alternate reading of the same characters for ude-jime (reading 絞 as shiboru as opposed to shimeru).
