No.
You can look online to find a ninjutsu dojo near you. You could also use YouTube to find videos of ninjutsu techniques and learn from that.
Ninjutsu is taught today through the Bujinkan, which is a collection of nine ryu-ha (lineages) - 3 specifically Ninjutsu and 6 being of Samurai origin. There are quite a few Bujinkan training locations in Southern California - some actual dojo's and others training groups that meet in public places (like parks). If you're close to Moorpark, CA, there is a Ninjutsu dojo, called Todai Dojo. They have a website, Moorpark Ninja).
Ninjutsu, or the art of the ninja, involves a large number of varied disciplines. In addition to armed and unarmed combat, the disciplines of ninjutsu also cover disguise and impersonation, and espionage. One can learn the martial arts skills from various dojos (though the authenticity of instruction may be questionable) in the US or UK - alternatively, one can seek instruction in Japan (though acceptance in a dojo may be unlikely).
there are ninjutsu schools in Egypt
Depends on what school of learning you follow. In one school of ninjutsu, you must travel to Japan and go to the Hombu dojo. There the "sakki test" is administered. If you pass, you become a fifth degree blackbelt in Ninjutsu. However, you do not have to become registered to be a ninja (or at least a ninjutsu master - becoming a true Shinobi is another story entirely. If you want to become a true ninja, you do not want your identity revealed, and so you don't register. Instead, you find a Jonin who is recruiting and you agree to become a Genin.). All you have to do is master the art of ninjutsu - then learn to live for the secret aspects of war: assassination, spying, etc.
