There are similarities too: The underlying gross -- meaning broad, not 'yuck' -- body movements are the same. The jiu-jitsu techniques add more pain by way of additional locks, strikes or strangles.
In class this week we looked at and practiced several of the judo hand-throws, immediately followed by one or more of their jiu-jitsu relatives:
- Tai otoshi (Body drop, Judo): Throat Attack & Double-strike turning throw (Jiu-jitsu)
- Uki otoshi (Floating drop): Lapel choke takedown & Sleeve pivot throw
- Kuki nage (Minor floating throw)
- Hiji otoshi (Elbow drop): Defence against a straight-arm choke from the front
- Mochiage otoshi (Lifting drop)
- Sukui nage (Scooping throw)
- Sumi otoshi (Corner drop): A follow-on to the Come-along armbar
- Obi otoshi (Belt drop)
- Kata ashi dori (Single leg drop): Pressure-point take-down to the lower leg
- Ryo ashi dori (Double leg drop)
There are, of course, others.
