OK, if you look through this thread you will see that twice (and 2 different) Hoya exec's state that Hoya "ownes" Tokina.

My guesstimate is since Tokina/Kenko are a LTD. company their "private stock" may well be owned by Hoya in a majority stake. This appears to be one of those more convoluted relationships.
For $443 US you may be able to find out for sure.

Ogl I used to strongly believe the same thing (Tokina independence) but that wall is crumbling a bit. It still may be true but the pendulum is swinging to some sort of "ownership".
Both Tokina and Kenko are pretty dependent on Hoya...
