Is it in nage no kata? Which set is it in? You mentioned Kata so I'm only thinking in the nage no kata, maybe that's throwing me off.
Possibly uchi Mata?
EDIT: Matt D'Aquino on Uchi Mata
University of Judo - Essential Uchimata setups: http://youtu.be/grz2X63WGe0
It isnt tai otoshi as there is no knee drop.
I thought of the throw as harai like as i load up uke on hip and kick leg back, but the throw itself isnt harai.
This is a good video, I like his setups a lot. Embedded for you:
O Guruma maybe?
it's much easier if you spin into it. it's hard as fuck to hit statically. you've gotta lead them to that side and basically do a sidekick.
it sets up like this in real time, but usually with a faster spin. you're basically trying to get out in front of the circle.
it feels 'wrong' to me too. like if uchimata or harai or osoto are thrown from 12:00-6:00, this damn is like tilting it all that 45 degrees and throwing from 9:00-4:00
Thinking "hip throw" helps me with harai. I like Hane Goshi too, seems like I hit it better.
