Ko-uchi-gake
(minor inner hook)
"After breaking Uke's balance to his right back corner, Tori
hooks Uke's right foot with his left from the inside and throws
Uke to the rear. Idealy Tori hooks Uke's leg with his instep of
his leftt foot and drives Uke to the rear."

This technique can be done either side (left or
right)
