The techniques in Tsuzukiwaza 14 are carried out sitting (Suwariwaza), only the shihonage at the end is in standing. The attack is Ryotetori. In Kokyunage 4, the first attack takes place while sitting, the second from standing. After the first Kokyunage 5 follows the first Kokyunage 6. That is, Uke falls with Kokyunage 5 (hakucho no mizumi) into the area behind Nage and then attacks from the back.
Suwariwaza is a traditional Japanese form, as people sat in Seiza on the tatami. It is a good exercise for acting when sitting and may even be practical.
Uke wants to overthrow the seated Nage. To do this, he blocks his arms and presses them against his thigh. Then he can push him with his head or torso. When Nage fights back with arm movements, a combat arises. Instead, Nage only puts his wrists in Nikyo form, and sends his Ki to Uke's shoulders. This creates a connection to Uke.
