Jiki in Japan
There are several surviving lines of Jiki Shinkage-ryu in Japan. Kashima-shinden Jikishinkage-ryu does not have a soke, rather shihan with complete transmission taught indepenently but collaborated at times with one another, to greater or lesser extents as they so chose.
I have collected below links to video clips from different groups that are available online. Most of the footage below concerns groups that flow down from the teaching of Kawashima Takashi and Ōnishi Hidetaka. There is one old Scanned film available of Onishi Hidetaka practicing Hojo and a short clip of opening enbu ceremony conducted by Kawashima Takashi.
Namiki Lineage
Some films related to groups from Namiki Yasushi's Tokyo dojo, inherited first by Ito Masayuki and then Yamada Himeji, can be found below:
Namiki Yasushi and Ito Masayuki are the teachers Dave Hall trained with in Japan. The Sounkai specifically is the line of Namiki Yasushi through his sons, which split from Yamada's dojo after the death of Ito Masayuki:

Hayakawa Lineage
Jikishinkage-ryu Sohonbu is led by Wakayama Satoru, who is recognized by the Nippon Kobudo Kyokai and is the successor to Iwasa Minoru, who led Jikishinkage-ryu Hyakurenkai:
- 33rd Annual Kobudo Enbu, 2010
- Meiji Shrine Demonstration, 2015
- 43rd Annual Kobudo Enbu, 2020
- Chiba dojo enbu in 2010
- Hyakurenkai Enbu in 2015
These are major events and so the video footage is of higher quality. The Mino-den Jikishinkai, which is a related group, also has video available:

I'd characterize the Mino-den practice as intense to the point of sacrificing too much in terms of posture and body organization for power and speed in my opinion.
