Taigi 29 - First Technique
The forerunner of Tsuzukiwaza 29 is Taigi 29, Tachi-Uchi, from Tohei Sensei. Tachi-Uchi 太刀打ち means "crossing the blades, fighting".
Yoshigasaki Sensei has split the first technique of this Taigi, Kote Uchi, into five individual forms. In this way, the logic of the techniques is better to understand. Kumitachi 組太刀 means "sword exercise with partner/in pairs".
