[quote=Niall Matthews;264341]In other budo there doesn't seem to be any confusion about what kubi nage is - it's basically all the same technique. It's a throw from a controlling headlock. The judo version here is a slight variation (from tai otoshi with an extended leg); the sambo and BJJ variations are orthodox koshi waza (koshi nage in aikido).
In Yoseikan Budo, kubi nage is the Judo version described here. Basically it's tai otoshi from a headlock.
