Kami verneration was already part of Japanese culture for centuries. There were local shrines and cults everywhere with most attached to Buddhist temples. Tengrism is completely artifical with no connection to everyday religion in Turkey or to ancient pre-Islamic Turkish beliefs. Its what historians call an invented tradition. There is no connection between modern Tengrism and what a Turkish nomad might have believed 2,000 years ago. The word Tengri or Tankari doesn't even refer to a seperate deity, its just a generic name for God used in Chaghtay Turkish as a synonym for Allah or the Chinese idea of Tian or Heaven.

Your assuming that there's an easy distinction between Islamic and pre-Islamic ideas, when in fact religious and spiritual ideas move around a lot and mix together and evolve all the time. You can't untangle them so easily. Shinto and Buddhism are still not totally seperate even today. An outsider might look at Afghan villagers appeasing mountain spirits and see it as preserving some pre-Islamic belief, but those villagers don't see it that way. Half of those "pre-Islamic" things you've listed are just mundane cultural variations not even distinct rituals linked to beliefs. Search for an authentic pre-Buddhist or pre-whatever tradition and you won't find it because everything is already mixed up anyway.
