Judo shime-waza comprises three types of technique:
The most famous of the third type is the (competition-banned) do-jime, but it is also possible to submit an opponent via a similar mechanism in a kesa-gatame hold.
Apart from these two shime-waza, are there any other body constriction techniques in judo?
Yes, there are other constriction techniques. These are a few examples, not meant to be exhaustive. As a philosophical matter, I think you should always be looking to further break uke's structure and constrict their movement and breathing; this is maximum efficiency.
yoko shiho gatame: Tori is on the side with extended legs, one arm around the head, and the other arm through uke's legs high on the thigh grabbing uke's belt. Tori presses down with the chest on uke's chest while pulling both arms toward's tori's hips. The dual action increases pressure on uke's chest. This arm action is a common warmup drill where you lie face down on the mat and pull yourself across the mat using your arms but not legs, sometimes called chest pulls or Mat putzen (mat cleaning because it has the effect of sweeping the mat area).
kuzure tate shiho gatame: Tori ends up on top, with tori's left arm between uke's left arm and head, grabbing uke's belt behind uke's back. Tori's head helps to control uke's left arm and tori's right hand is free to brace against bridging. Constriction is most effective when tori traps uke's right arm across uke's body between tori's and uke's bodies. From this position, tori presses down with their chest while simultaneously pulling with the left hand belt grip.
Tori can achieve this position by transitioning from a kami shiho gatame with both arms underneath uke's arms grabbing uke's belt. Tori then sits their left leg through on the right side and then steps over uke's body with the right leg to end up astride, maintaining the belt grip with their left hand throughout.
ushiro kesa gatame: this is very similar to kesa gatame in application, but I think this is even more effective in the reverse position. Tori twists while winding uke's arm and body to constrict.
I do not expect these constrictions to result in a submission or unconsciousness; they are more demoralizing and uncomfortable.
