Ballpark Estimate: $6,000
If you can do a cartwheel, a chin-up, and are really good at sneaking around, odds are, you can become a Ninja. Before trivializing the above admissions criteria, consider who it excludes: the overweight, the uncoordinated, the weak, and the loud.
To become a Ninja, there are two categories of expenses- training and gear. While the gear is undoubtedly cool and sexy, you need the training first.
There are plenty of “Ninja Camps” that you can attend for a thousand dollars or so per weekend where you get a certificate and possibly some new skills. However, if you’re serious about true Ninjitsu training, it will take at least five years studying with a Ninjitsu expert to attain the equivalent of a black belt in Ninjitsu. This is assuming attending classes 3 times per week for 5 years, or about 500 classes. An average price for a decent martial arts school will cost at least $100/month. So, for 5 years of training, expect to spend at least $6,000 in tuition.
There is no doubt that Ninjas have the coolest weapons and gear in all of the martial arts world. From swords to throwing stars (shurikens) to grappling hooks, foot spikes and hand claws, Ninjas have it all.
