Ninjas are masters of spying, sabotaging and assassinating. Ninjas are recruited from stealth chain building, such as a Gambling Hall, each one allowing the recuitment of one extra ninja. Ninjas can be used for:
Ninjas can make rival generals or agents "Disappear".. for a small price, of course. To assasinate, select your ninja and right click on the soon-to-be victim. A panel will appear with the targets and the chance of success of each one. The percentage depends on the skill of the ninja and of the target; Daimyos will be harder to kill than monks, for instance.
Every army, fleet, agent or anything belonging to you will uncover information about rivals if they are in close range. Ninjas can reveal more details than other agents or armies.
Ninjas have a large line of sight, they can go discovering the map or improve the line of sight of an army or castle. If a ninja is embedded into an army, it increases it's movement ability and protects it from being demoralised by enemy monks or missionaries.
Ninjas can damage enemy buildings. Select your target wisely. If you wish to cause unrest you may want to target temples, but if you destroy a farm, they will lose money and may be unable to pay the upkeep for their armies, for instance.
Ninjas can also sabotage armies, poisoning food and water supplies. The army will recieve slight casualties and not be able to move for a turn.
If a ninja is garrisoned in a castle, he will police the streets and make sure no enemy agent is freely walking the streets undetected, and may even get the chance to eliminate them. He also increases the line of site of the castle. It is free, but your agent gains very little experience while doing this.Ninjas gain experience through successful subterfuge. Each rank gives the ninja more points to spend on improvements and a total of three retainers. Sabotaging buldings or small armies are a good way to train your ninja up, as they are cheap and do not have many risks.

The Hattori Clan is a specialist ninja clan, and get extra benefit for their ninjas. The higher rank the ninja is, the better it will be. But you cannot gain all the skills, and you will have to chose what your ninja specialises in. Shall he be a knife in the dark, killing many? Or maybe spying on the enemy? The choice is yours.
It may be a good idea to keep your ninjas close to each other. One can scout the field and clear the way for another to enter and kill the target.
