Hane Goshi Gaeshi (跳腰返 : はねごしがえし) is a throw in judo and is categorized as a foot technique, Ashi-waza. It is one of the techniques adopted later by the Kodokan into their Shinmeisho No Waza (newly accepted techniques) list.
Uke attacks Tori with right hane goshi, as he does so Tori counters by hooking his left leg around Uke's lower left leg and reaps it to the right.
Alternatively, lift Uke up and reap his legs to your left with your right leg. Similar to harai goshi gaeshi, the counter to the sweeping hip throw.
