Tissier’s demonstration is particularly smooth as he brings Uke‘s striking hand quite low before he flips his hand over to grab securely.

Both Doshu and Tissier start yonkyo with the same movement as ikkyo (slide out and step in deep right away).

Yonkajo Osae

I started comparing Yoshinkan versions to Aikikai versions so I will do the same with yonkajo. You will notice that in the clip below Shite starts yonkajo with the same footwork as ikkajo: shuffle sideways and in. One neat addition they do is a (kind of) nikyo pin after Uke is down. I say ‘kind of’ because he does not clamp Uke‘s shoulders with knees but instead leaves one leg up.

I’ll also point out that the Yoshinkan Shite initiates the attack – he strikes before Uke can.
