Glaucus
Omono
This is the festival organized by the Japanese Satsuki Association (the enthusiasts/hobbyist club).
The video is 4K 30 minutes professional grade, so basically perfect camerawork (gyroscope, panning) and quality.
Plaques that show the bonsai artist, cultivar, and what award they won are shown, but of course hard to read.
Apparently, the person who recorded this video also has this instagram:

In case you want a wrap up of the Kokufu.
