Part 17 of the Yasuda Ryu Ninjutsu Densho (From Soke’s book Ninpo Taizen)

For parts 1 through 16 please see my previous blog post in the translations section.




When the scouts are doing shinobi activities, other than when they should be infiltrating a castle, it is good for the shinobi to have three days of food (Summer. Winter are different). As a rule, after the fact, the main troops will help (with food). Don’t forget! Your communications with the main troops. When infiltrating it is good for the scouts to inform the main troops of their movements.

The purpose of infiltration activities is for attacking. Aside from hiding oneself in the enemy’s sphere of influence to gather intelligence for five years, ten years, twenty years and informing the allies, there are movements for attacking immediately. For the shinobi it is better to be prepared well ahead of time. However, the shinobi who infiltrates the enemy’s lands often meet with the enemy (informants), and at times allies are betrayed. Be careful of this. Also, there are often times when the enemy’s generals know the missions of these people (informants) and monitor us until the time of our attack. Be careful of this.
