Irimi

'Irimi' means enter in Japanese.

• When an attack comes head on, in Aikido we instantaneously slide to the side, enter the opponent's dead angle and avoid the blow.

Do we have the courage to enter new territory?
Go into the unknown, where we are not clear where is the beginning or where is the ending.
What is clear is our intention,
Though we know not how to achieve it yet - Azim Pawanchik

As soon as
The enemy before me
Attacks with his sword
I am already
Standing behind him

When enemies
Rush in to strike
Take one step in
To the side,
And cut deeply! - Morihei Ueshiba
