Uchidachi:
tombo – kirisage – torii – tombo
Shidachi:
mukei – massugu – seigan – yokoraitō – kobouchi – menuchi – massugu – mukei
Sangaku teaches us matsukoto; to entice the opponent to attack. It also teaches us the principle of sassōkoto, to open up a striking surface on our body and through the choice of position, kurai, to counter the attack while moving so that the opponent misses his target and we hit ours.
In four waza, uchidachi initiates from tombo no kurai while shidachi starts from mukei no kurai, which is the kurai that we usually start from. Shidachi then assumes massugu no kurai. A few steps before maai, he steps back with his left leg to seigan no kurai. When uchidachi reaches issoku ittō no ma and launches a strike, shidachi straightens his body by stepping back with his right leg next to his left, his right foot lightly touching the ground, and lifts his sword to yokoraitō no kurai. In the same movement, shidachi steps to the right with his right foot and rotates his left shoulder joint and slashes kobouchifrom seiraito no kurai, locking the opponent's sword, hands and arms with kuraizume. At the same time, the left leg also follows and the shidachi creates a new center line against the uchidachi.
From this position, the shidachi has won because the opponent cannot fend off an attack, usually with a tsuki. This thrust is not practiced in waza because it is dangerous, even when using blunt bamboo swords. During the first three waza, the uchidachi retreats and the shidachi steps forward and strikes the head with the menuchi. The strike is intercepted by the uchidachi with torii no kurai. The strike is called nikiri, to advance with a subsequent new attack.
Uchidachi returns to the starting position in tombo no kurai; the shidachi in massugu no kurai and ends in mukei no kurai.
