I found ae86lan adding these videos to his favorites on Youtube. The three videos are footage of touge runs in May 1990 with mainly AE86s, AE82s and Starlets. I must warn that there is hardly any drifting involved in these videos: most cars car grip driving up and down the touges around Chichibu.

Here is another video from that very same night:

And last but not least, another one from a different night going up and downhill:
