Kigami's credited for layout(solo) and key animation in this movie.
I guess he's at least responsible for the rough animation of these scenes.

I really liked how the film was ambitious in 3D camera panning. Makes me wonder if there's other traditionally animated media that employs background animation most of the time.

Aside from those animations for 2D video games there's Osamu Tezuka's Jumping.

The Captain Power series of training videos feature 3 episodes of non stop background animation. There's some looping and reusage, but there's a lot of impressive work there. A young Shinya Ohira was one of the ADs. http://youtu.be/1FAuDYqaW58?t=2m5s
