Shinya Aoki & Imanari GIGAPACK!
Salepage : Shinya Aoki & Imanari GIGAPACK!
Here you will find all three of Shinya Aoki’s grappling instructionals along with Imanari’s disc.
See the .txt file for the chapter listing.
They are all in Japanese; I was only able to find the first disc with a subtitle file. No worries, each technique is shown multiple times from multiple angles.
